Are Remote Car Starters Safe and Secure?

Remote Start Safety

Many consumers ask if a remote car starter affects the safety and security of their vehicle. A while back, we talked about warm-up thefts and how thieves prey on people who start their vehicles with the key to let them warm up in the morning. Leaving your key in your vehicle is, of course, begging for trouble, and a properly designed and installed remote start system is the perfect solution. Let’s talk about how car starters work in terms of theft prevention and the safety of those working on or around the vehicle.

Remote Started Vehicles Are Safe

Modern car starter systems integrate with the security and anti-theft systems built into modern vehicles. Digital communication on the CAN and LIN bus networks in the vehicle not only handles all the required authentic protocols, but many of the ignition and start commands can be issued by data as opposed to the conventional analog signal method from days gone by. This technology has eliminated the chance of a vehicle being “hot-wired” by crossing a few wires under the dash like in a scene from an ’80s movie or TV show.

Remote Start Safety
Most push-to-start ignition systems use complex digital commands to start the vehicle. This technology makes these cars almost impossible to hot wire.

Most car starters ensure that the doors are locked after the start process is complete. The systems also require the presence of a factory-issued wireless fob or the use of the key in the ignition. Finally, if the vehicle isn’t “started” with the key (either mechanically or electronically), the starter system will shut down as soon as the brake pedal is depressed. The latter scenario assumes that a thief was able to get into the locked vehicle.

Starter Safety for Mechanics and Technicians

If installed properly, a modern remote starter will include a hood pin or a tilt switch, or it will be integrated with a factory hood pin so the system is disabled when a technician or mechanic is working on the vehicle. Likewise, a properly installed starter system will include a valet switch or a way to put the system into a Valet mode using the remote. Once in Valet, the remote start functionality is disabled, but door lock and unlock functionality continues to work.

Remote Start Safety
Many new vehicles include a pin switch to detect when the hood is open. If installed properly, the vehicle cannot be started remotely with the hood open.

Another safety feature is over-rev production. If the engine speed exceeds a preset level before the ignition is turned on with the key or start button, the engine will shut down automatically.

Manual Transmission Starter Safety

Dozens, if not hundreds, of discussions have looked at the safety of remote car starters designed for use in vehicles with manual transmissions. The question of just how safe these systems are depends directly on the solution you purchase. A basic solution requires that you use some type of reservation mode. The process involves stopping the car and setting the parking brake, then sending the start command from the remote control to the vehicle. The owner can turn the engine off and exit the vehicle. The engine will continue to run. Once the lock button is pressed on the remote, the system shuts the engine down. If a door is opened before the car is started, the reservation mode is canceled.

Remote Start Safety
Many remote car starters are designed specifically to work with cars, trucks and SUVs equipped with manual transmissions.

Some companies take manual transmission starter safety even further by including a motion sensor with the system. If the vehicle moves when the engine starts, the ignition is disabled. Compustar systems include a sensor called the DAS2 that monitors motion, shock and glass breakage to ensure that the vehicle is safe and secure.

Choose Your Remote Starter Carefully

As we’ve said several dozen times, the performance and reliably of your car starter system depends on the products you choose and how those solutions are integrated into your vehicle. Lots of inexpensive products are available for every category of the mobile enhancement industry. Your satisfaction depends on your choice. In terms of a car starter, saving a few dollars may not be wise. Drop by a few local specialty mobile enhancement retailers to learn about the solutions that are available for your vehicle.

Stop Taking Car Audio Advice from the Internet

Car Audio Advice

For more than 20 years, car audio enthusiasts have been asking their peers for advice on the internet. These discussions and debates started on forums like Carsound.com and Termpro.com then moved to social media platforms like Facebook and Reddit. As more and more people joined in these discussions, the clarity, focus and information accuracy has suffered. Now, a simple question about upgrading speakers or adding a subwoofer to a vehicle could yield an accurate answer from an experienced professional or lead you in a completely wrong direction. Let’s take a quick look at the complexities of getting car audio information from online resources.

Who Are the Experts?

Before you decide to ask a question about modifying or upgrading your vehicle with new audio equipment, consider the expertise and training of the people you are asking. Are they hobbyists? Do they have hands-on experience? Have they attended manufacturer or industry training events? The relevance of this information depends on the age of the vehicle you are working on. If it’s a ’90s Honda Civic, then even a rudimentary understanding of physics may be adequate to supply you with usable information.

Car Audio Advice
If this is your idea of a car audio upgrade, please drop by your local mobile enhancement retailer for some advice.

If you are asking about a vehicle built in the last few years, specific knowledge of acoustics, advanced signal processing and detailed system testing methodologies are required. Upgrading a car or truck that uses MOST (Media Oriented Systems Transport), CAN (Controller Area Network) bus or A2B (Automotive Audio Bus) can be impossible without the correct hardware interfaces. The days of checking wires with a voltmeter are long gone.

Car Audio Advice
Companies like PAC Audio make interfaces for vehicles with CAN bus-controlled amplifiers.

What Are Your Goals?

One of the most common questions people ask online is, “How do I get better sound?” If you walk into the showroom of a professionally trained mobile enhancement retailer, the product specialist will likely reply by asking a series of questions. These questions are designed to help develop an understanding of your existing audio system and the specific aspects that you want to improve. The specialist may ask to have a listen to your vehicle so that you can provide examples of what you enjoy. As you can imagine, this is completely impossible through any form of online information exchange. Keep this in mind before purchasing an upgrade online.

Car Audio Advice
Auditioning car audio equipment is an important part of getting the right solution for your vehicle.

Troubleshooting Problems

Another popular series of online questions focuses on resolving installation issues. Problems with wiring, component mounting and system configuration are very popular. If you have a problem with a radio or amplifier not turning on, someone with basic electrical knowledge can likely provide you with a few things to check. You will, however, need a multimeter to perform the tests. Odds are, if you own the meter, you should already know enough about electrical theory to know what to test, but that’s not always the case. If you don’t own a meter, well, you need one. The same applies to figuring out why a radio might not turn on or why a speaker has stopped working. Having the right information without the right tools does you no good. Visiting a local car audio shop will likely save you a lot of time and hassle.

Car Audio Advice
Many professional installers have invested thousands of dollars in test equipment to ensure that they have reliable information for diagnosing issues.

Audio System Component Selection

Asking questions about which car audio components to buy is perhaps one of the worst things you can do to get good advice. First, the person answering the question needs to have a complete understanding of the application. Say you are asking about new speakers for a car. The answer needs to take into account the diameter of the existing speakers, the mounting depth requirements, the need for and availability of mounting adapters and spacers, and the capabilities of the person who will be performing the installation.

Next, the issue of quantifying the quality of a speaker is one that even many professionals struggle with. What makes one speaker better than another? Some of the criteria are simple and easy to understand. Power handling specifications are important but can be misleading if the specification isn’t quantified properly. You can learn more about this complex subject here.

Car Audio Advice
This frequency response graph of this 6-inch driver shows a roll-off that’s -3 dB above 100 Hz and a massive dip at 2.2 kHz. These issues need to be taken into consideration when designing the audio system.

Looking at speaker frequency response graphs can, in the eyes of someone with experience, tell you a lot about the speaker design. Ripples in the response measurements show where distortion may be occurring or where energy is stored and released by the driver as unwanted output. In terms of looking at graphs, more output isn’t always better. Finally, a look at the drivers’ Thiele/Small parameters and an associated simulation in computer software can tell a lot about the suitability of a driver for a specific application. For example, a small midrange driver with a high total Q-factor may not be suitable for use in a speaker pod on a dash or A-pillar.

Visit the Experts for Valuable Car Audio Advice

If you’re interested in upgrading the audio system in your car or truck, do some research. Start by finding out the car stereo shops in your area. Look to see if they have any Mobile Electronics Certified Professionals (MECP) on staff. MECP is a good starting point to ensure that you are talking to someone who has a commitment to product training and industry knowledge. Finally, ask to see examples of and hear their work. They should have demo vehicles available to audition. Only after you’re comfortable about the shop’s expertise should you begin the process of inquiring about upgrading your vehicle.

Product Spotlight: Compustar CS852-A Car Alarm System

Compustar CS852-A

A car alarm system like the Compustar CS852-A helps protect the contents of your car or truck and dramatically reduces the chances of vehicle theft. As a step-up solution from the CS697-A, this alarm system offers increased remote-control range and a high-output siren to ward off would-be criminals.

Reliable Vehicle Theft Protection

At the heart of the CS852-A is the Compustar CM2400 Security Control Module. This powerful yet compact microcomputer can monitor the doors, hood and trunk of your car or truck to alert you if someone has tampered with your vehicle. An integrated dual-stage shock sensor monitors the body of the vehicle for impacts. A mild impact will trigger a warning blast from the included high-output 105+dB siren. An impact from car door or an inattentive driver that will cause damage to the vehicle triggers the full siren. The system can also flash the parking lights and sound the horn to attract even more attention and scare off criminals.

Compustar CS852-A
The 105+dB siren included with the CS852-A helps scare away thieves to protect your car or truck.

Thanks to the included E-LOCK starter kill relay, hot-wiring your car by conventional means is nearly impossible. Even if you have unlocked the doors with the key, so long as the alarm is armed, thieves won’t be able to start the engine.

Can I Watch Movies in My Car While Driving?

Watch Movies

Can I watch movies while driving? It’s a common question at specialty car audio retailers all around the world. Multimedia receivers capable of displaying video have been available since the mid-’90s, and while TV tuners, VCRs, DVD players and digital media playback have progressed over the years, so too have state and provincial laws. Let’s look at where things stand in terms of watching movies and streaming or recording videos while behind the wheel.

The Laws on Videos and Movies While Driving

Though the wording may change in your state or province, law enforcement agencies are very clear on the rules about watching videos while driving. In most states and provinces, having a display within view of the driver that shows video while the vehicle is in motion is illegal.

Exemptions to Video-in-Motion Laws

Most states allow video displays in a vehicle, so long as they are not visible, in any way, from the driver’s seat. Laws do allow displays for GPS-based navigation systems, vehicle status displays and camera displays. Florida specifies that these add-on devices must not hinder the driver’s line of sight.

Watch Movies
Dashcams with video displays like the Momento M4 and M5 are allowable in most states and provinces, provided they don’t obstruct the driver’s vision.

Video event recorders such as a dashcam are also typically allowable. However, some states are very specific about their guidelines. Delaware requires that backing, parking, object detection, passenger monitoring must be disabled at speeds above 12 miles per hour.

What about Tesla and Land Rover Vehicles?

You may have heard late in September 2019 that Tesla rolled out Software Version 10.0 for its Model S, Model X and Model 3 vehicles. This software update includes a feature called Tesla Theater that allows the large display screen to show Netflix, YouTube and Hulu videos. They also added Cuphead to the collection of games in Tesla Arcade. Not surprisingly, these entertainment options are only accessible while the vehicle is parked.

Watch Movies
In vehicles capable of showing movies or streaming video on their displays, those features are automatically disabled when the vehicle is in motion.

Back in 2010, Land Rover equipped the Range Rover with a 12-inch touchscreen in the dash and a technology known as Dual View. When looking at the screen from the driver’s seat, you would see the usual radio or satellite navigation system display. A passenger looking at the same screen could watch his or her favorite DVD. This parallax barrier technology was also available in the 2009 S-Class from Mercedes-Benz.

Don’t Override Video Lockout Systems

If you have been shopping for a new multimedia receiver for your car or truck, the temptation to override the video-in-motion lockout is indeed tempting. Different radio manufacturers have different requirements to allow video to play while parked. Some require the parking brake to be set. Others use information from the GPS receiver to prevent DVDs or digital video from playing while the vehicle is in motion.

Watch Movies
Aftermarket multimedia receivers like the Sony XAV-AX8000 are capable of playing a multitude of digital media file formats – as long as you are parked.

If you’re traveling at 70 miles per hour, your vehicle is covering more than 100 feet per second. Also, consider how long it takes to stop when you slam on the brakes. A high-performance sports car like a 2019 Porsche 911 gt3 RS takes about 129 feet to come to a full stop from 70 mph. A big pickup truck like a Chevy Silverado takes roughly 178 feet in perfect conditions. Even a glance at a video display could have you on top of another vehicle, an animal in the road or a worst-case-scenario, a pedestrian.

Always Drive Safely

Whether you’re looking at a navigation screen or laughing at a friend’s joke, paying attention to the objects and vehicles around you while driving is your top priority. Watching a movie or the latest episode of Cletus McFarland on YouTube while driving is a really bad idea. Drop by your local specialty automotive enhancement retailer to find out what entertainment solutions are available. They will let you know what the local laws are about video-in-motion and help you choose a perfect and safe solution for your vehicle.

Why Can’t Car Audio Amplifiers be Smaller?

Small Amplifiers

Wouldn’t it be nice to have a really small car audio amplifier that would make lots of power and fit in the palm of your hand? Based on experience, we’ve come to expect that consumer electronics increase in power and capability while shrinking in size as new generations are released every year or so. For computers, Moore’s law has held true with a doubling of transistors in a computer processor every two years. That same philosophy doesn’t work for amplifiers. Here are a few things to think about before you rush out to buy a really small amp for your car or truck.

Car Audio Amplifier Efficiency

Mobile audio amplifiers need to have a heat sink because they are not 100% efficient. This lack of perfect efficiency means some of the power that goes into the amp is converted (or wasted) as heat rather than being output to your speakers. For a Class-AB amp, efficiency at 1/3-rated power might be around 35% and a Class-D amp would be up around 70%. Even at 70%, if the amp is producing 100 watts of power, it’s still turning 43 watts into heat.

Small Amplifiers
The Helix C Four uses a cooling fan to increase the thermal capabilities of a heat sink to prevent over-temperature shut-down.

This heat, if not controlled, will damage the components in the amp. To prevent this, amplifier designers attach heat-generating devices to a heat sink. Most modern amplifiers use aluminum extrusions to wick heat away from the transistors and MOSFETS that handle large amounts of current. The heat sink needs to transfer this heat into the air around the amp and as such, it needs to be a specific size for a given amount of energy transfer.

What Happens When an Amplifier Heat Sink Is Too Small?

Sadly, there are lots of amplifiers on the market that don’t have large enough heat sinks. What happens when these amplifiers get hot? Depending on how the amp was designed, it may simply turn itself off at a certain temperature. Some amps include circuits that reduce the voltage of the power supply in hopes of reducing the amount of power being wasted.

Small Amplifiers
The ARC Audio Moto720 is one of the most efficient amplifiers on the market. Only 8% of the power fed to the amp is converted to heat.

If you live somewhere that experiences high temperatures, or you listen to your music at high volume levels, have your local specialty mobile enhancement retailer help you choose an amplifier with a large enough heat sink that it functions reliably.

What Else Limits the Size of a Car Audio Amplifier?

Aside from needing enough space to physically house the power supply, signal processing and output devices, another factor that puts a limit on the size of an amplifier is having enough room for the various connections and controls required to make the amp work. Once a designer has found room for the power, signal and speaker connections, he or she needs to find room for sensitivity and crossover adjustments, as well as switches for crossover functions. Subwoofer amps often need a jack for a remote level control, and that space is part of the chassis design. If the amp needs bandpass crossovers, an infrasonic filter and signal routing switches, the end panels of the amp can very quickly run out of space.

Small Amplifiers
Like the new Audison SR amplifiers, many companies have moved to mounting the adjustment controls to a secondary circuit board on the top of their amplifiers.

Is a Small Car Audio Amplifier Better?

As we mentioned in our article about compact amplifiers, cramming a lot of circuitry in a very small space has some drawbacks. In almost every example we’ve seen, really small car audio amplifiers have worse signal-to-noise performance specifications than their larger counterparts. The last thing you want after having your mobile audio system upgraded is to hear hiss between songs.

Choose Reliability of Size

Unless you are trying to fit an amp into a very small location like the fairing of a motorcycle, you are always better off choosing a solution with a relatively large heat sink and, most importantly, great specifications. Drop by your local specialty mobile enhancement retailer today to audition the different amplifiers available to suit your car audio system upgrade.
