It should come as no surprise that supply chain issues have wreaked havoc on the automotive industry. From the need to shut down production facilities to shipping vehicles with missing features or components, automakers’ inability to get the parts they need has changed the new vehicle buying experience. While the aftermarket can’t supply a body control module or ABS module, we can help with many components the OEM suppliers can’t deliver.

Missing Ford Bronco Features

The mighty Bronco is Ford’s answer to the Jeep Wrangler. But, sadly, its popularity has been hampered by suppliers’ inability to deliver vehicle components. One of the better-known issues is the missing subwoofer and amplifier. While a cursory inspection makes it look like a speaker and an amp are attached to the plastic enclosure, more research reveals that those components are nothing more than window dressing. For example, if you removed the subwoofer from the enclosure, you’d find it had no voice coil, tinsel leads or motor assembly.

Disassembling the amplifier shows that the circuit board isn’t populated with anything other than the input and output connectors. The large red X on the amplifier theoretically identifies it as a non-functioning unit.

According to many sources, Ford offers a discount to owners to compensate for that lack of functionality in the subwoofer system. A few dollars in your pocket might be nice, but it doesn’t make up for not having good bass in your audio system. Fortunately, the aftermarket can deliver where the manufacturer has fallen short. Drop by a local mobile enhancement retailer and talk with them about a subwoofer that will fit into the factory enclosure and a compact amplifier than can drive that sub. This might be an excellent opportunity to upgrade to a subwoofer solution that will make you smile. Ask about an upgrade to a subwoofer that can deliver much better low-frequency extension and excellent output.

We’ve heard that Porsche dealers are suggesting to clients that they forego buying premium audio systems because the amplifiers are in short supply. But, of course, the aftermarket can easily provide a high-quality amplifier with integrated digital signal processing to power all the speakers. In addition, you can upgrade the speakers to units with better clarity, improved low-frequency performance and enhanced output capabilities. Moreover, almost any specialty mobile enhancement retailer can make the audio system in a Porsche sound amazing.

Missing Heated Seats

According to many reports, Ford F-150s and Broncos and Chevrolet Silverados are being delivered without heated seats. While this is less of a problem if you live in Florida or Texas, for those of us in the North or Canada, getting into a vehicle in the winter brings an expectation of this luxury heating solution for our posteriors. Once again, an expert mobile enhancement retailer can install seat heaters in almost any vehicle that doesn’t have the leather or fabric glued to the foam. Most aftermarket heating solutions include a simple mechanical high or low switch that can be left on so that the seats start warming up as soon as the vehicle starts. Adding a remote car starter is an excellent investment to get the heat into the seat before you get to the vehicle.

Lighting Upgrades

Jeep supposedly has trouble delivering their LED headlight assemblies on the newer Wranglers. If you end up without LED lights, a reputable mobile enhancement retailer can help get you the lighting performance you want with a high-quality LED bulb upgrade. Make sure the upgraded bulbs are designed specifically for the light assemblies in the vehicle (projector or reflector) and that the hot spot is centered on the road well out in front of the vehicle. You don’t want the headlights to light up the area directly in front of the vehicle brightly. Also, ensure that the cut-off is appropriate and won’t blind oncoming drivers.

Ford Bronco Hard Tops

Tangential to those supply issues, there is another concern on the Ford Bronco: The optional hard tops from the factory supposedly have serious quality issues, including the fiberglass delaminating and cracking. But, once again, aftermarket options can fulfill your needs and help avoid the frustration of dealer claims that cracks in a component are somehow normal.

Companies like Rally Top, Anderson Composites and Advanced Fiberglass Concepts, to name a few, make aftermarket hard tops that don’t suffer from the same failures as the Webasto units that Ford offers.

Cordless Phone Chargers

There’s also talk that the 2022 Silverado was missing its cordless smartphone charging base. However, several aftermarket companies make wireless charging pads and even phone brackets. A local mobile enhancement retailer can mount one in your vehicle and wire it to activate when the engine starts. These are an excellent investment, especially if your vehicle has Apple CarPlay or Android Auto that uses a wireless data connection.

If you don’t have room for a dedicated charging pad, having a high-current USB charging port is another option. You can choose from USB-A or USB-C designs that include quick-charging capabilities to top off a modern phone or tablet quickly and efficiently.

Mobile Enhancement Retailers Can Install Missing Components

If your new car is missing a feature that should have been installed on the assembly line, or you want to upgrade your vehicle with a backup camera, parking sensors or a blind spot monitoring system, drop by a specialty mobile enhancement retailer today and talk with one of their product specialists. They won’t have a solution for every challenge, but they can likely resolve most issues so you can fully enjoy your vehicle.

If you’ve been paying attention to the car audio industry over the last decade, you know that the number of discrete channels available from quality amplifiers has increased steadily. Some better brands now have solutions with as many as 12 channels. So let’s consider why you might want more amplifier channels in your car audio system.

Car Audio Systems Using Amplifiers in Radios

The most straightforward car audio system would include a radio and a pair of speakers. This sound system would be adequate for letting you listen to the news or play your favorite music. Most radios include a small four-channel amplifier integrated circuit that can produce between 15 and 20 watts of power. With reasonably efficient speakers, that’s enough for many people. So, as a minimum, your car stereo system needs two channels to allow the system to reproduce a stereo audio signal and send independent information to the left and right speakers.

If you want the audio system to play a little louder, have a specialty car audio retailer add a second set of speakers to the rear amplifier channels built into the radio. Now, each speaker will receive 15 to 20 watts of power, and assuming the speakers are of the same efficiency, the system can play at least 6 dB louder.

When four channels of amplification are available, you can use the fader control to adjust the relative output levels of the front and rear speakers.

If you want a dramatic improvement in performance and output capability from a deck-powered audio system, we strongly suggest adding a subwoofer. Even a modest amplified subwoofer can make a significant difference to the perceived quality of your audio system. In addition, the dedicated subwoofer can reproduce low-frequency audio information at higher volumes.

Audio Systems with External Amplifiers

Let’s look at systems with external amplifiers. We’ll start with a basic two-channel amplifier. Most car audio amplifiers are capable of driving a 2-ohm load. The ability of an amplifier to drive lower impedances means your installer could wire two 4-ohm speakers in parallel to each channel without upsetting the amplifier. As such, you could use a two-channel amplifier to power four speakers with the two left speakers on one channel and the two right speakers on the other. Back in the ’80s and early ’90s, some car audio manufacturers suggested using 4-ohm speakers for the front and 8-ohm speakers for the rear with a two-channel amplifier. The goal was to reduce the power sent to the rear speakers to help improve the perception of the sound coming from the front of the vehicle. Remember, if you’re after the best sound quality, most amplifiers add distortion when driving lower impedances.

If you want to control the relative level of the front and rear speakers in your car stereo system, you’ll need a four-channel amplifier. Assuming the radio has front and rear RCA preamp outputs, the fader control on the radio will adjust the relative volume of the front and rear speakers.

One popular audio system configuration uses a four-channel amplifier with two sets of speakers and a subwoofer. The front and rear speakers would be connected to one pair of channels, and the second pair of amplifier channels would be wired in a bridged configuration to provide more power to the subwoofer.

If you want more system flexibility, try a five- or six-channel amplifier. The extra stereo channels will add the ability to adjust the relative volume level of the front and rear speakers while using a dedicated pair of channels in a bridged configuration or a high-power mono for a subwoofer.

Actively Filtered Car Audio Systems

If you want the most control over each speaker in your car audio system, dedicating an amplifier channel to each one is the best way. The challenge here is that the amplifiers must have crossovers that will allow each speaker to receive only the range of frequencies for which it is designed. Some higher-end radios include three-way crossover modes with high-pass filters for coaxial drivers or tweeters on the dash, bandpass crossovers for midrange or midbass drivers in the doors and a low-pass filter for the subwoofer. Many five- and six-channel amplifiers also include crossovers with adjustable range crossovers that can handle bandpass filtering on a midrange driver and a high-pass crossover for a tweeter.

The next step from the above system is to include a digital signal processor to handle the filtering, delays and channel-by-channel equalization. While radios like the Sony XAV-9500ES have all these features, very few (if any) radios on the market include channel-specific crossovers. In this case, you must include an external digital signal processor to handle the filtering, delays and equalization. If you want to use a mid and tweeter in the front and a subwoofer in the back, you will need a DSP with six outputs (three for the left and three for the right) and a five- or six-channel amplifier.

If you don’t already have an amplifier, you might want to consider purchasing one with a built-in digital signal processor. These all-in-one processing and amplification solutions simplify the installation and reduce the interconnect cables required to feed signals around the system.

The next step up takes two routes. First, if you have passengers in the rear of your vehicle or prefer to have the sound from your stereo wrap around you as you’d hear at a club or when listening to headphones, you might want to add rear speakers. You’ll need another pair of amplifier channels for the rear speakers. No name-brand car audio amplifier manufacturer (that we know of) offers a seven-channel amplifier. You’ll need to go with an eight-channel amp and use a pair of channels bridged to power a subwoofer.

The alternative is to move up from the three-way system to a four-way design with tweeters, midrange drivers, midbass drivers and a subwoofer. The benefit of a four-way system is that the midrange drivers can be placed higher in the vehicle – in the dash, at the top of the doors or in custom pods on the A-pillars or sail panels. These higher midrange mounting locations can improve the perception of stage height. A three-way front stage also allows each speaker to operate in a frequency range where directivity becomes less of an issue so that the audio system will sound better from both front seats.

Many eight-channel amplifiers include RCA preamp outputs that can be used to power additional amplifiers. A popular option for those who enjoy listening to music at higher volume levels is to bridge two pairs of the eight channels to provide more power to the midbass drivers, then use an external high-power amplifier to drive the subwoofer.

If you wanted to add rear speakers to the above configuration, you’d need two more channels for 10.

We aren’t going to delve into the world of re-amplifying premium factory-installed audio systems like Bose Centerpoint and Harman Quantum Logic Immersion. Those can quickly require 12 or more channels of amplification to cover mid-level systems. For example, some of the Harman audio systems included in vehicles from Lexus have 23 speakers and 16 channels of amplification. Dealing with these systems involves complex elements that include active noise cancellation and volume-based response changes, as well as signal delays and all-pass filters.

One last thought: You don’t have to choose a single amplifier with the number of channels you want. For example, you could use a two-channel amp for a pair of front speakers and a monoblock amp for a subwoofer for three channels. A popular system configuration is a four-channel amp for front and rear speakers and a monoblock amp for a sub. Some elaborate systems use two four-channel amplifiers for the front speakers. One amp would run the left tweeter, the left midrange and the left midbass from a pair of bridged channels. The other four-channel amp would power the three right speakers. This configuration can improve stereo separation a bit but is complex and expensive.

There are many other ways to configure car audio systems, and each has different amplifier channel requirements and benefits. This article covers some of the most common to help you understand what the product specialist you’re working with might suggest. Before shopping, think about how you like to listen to your music and how loudly. Provide that information to the team at the specialty mobile enhancement retailer you’re working with, and they can quickly narrow down the number of amplifier channels you’ll need.

Water and road salt are known to wreak havoc on the body and underpinnings of our cars and trucks in the winter. Even living near the ocean, where salt levels are high, can accelerate the rusting process. In this article, with some help from the automotive electronic experts at Motron Automotive Electronics in London, Ontario, we’ll talk about how water infiltration can cause serious problems with even relatively new vehicles. We’ll also discuss a few options for protecting the electronics in your vehicle to help prevent water damage.

Electronics and Water Damage

Water and road salt are a nasty combination. The mixture seeps into the seams between body panels to cause rust in the corners of doors, around wheel wells and near fuel filler doors. If you’re in and out of your vehicle often in the winter, your boots will track this nasty mixture into the vehicle’s interior, where it can damage the floor.

With newer vehicles, automakers are often challenged when determining where to mount computers, control modules and entertainment system components. These parts often end up under the seats of a car, where they can come in direct contact with this evil and destructive salt water. The result is damage to costly components, especially audio system amplifiers. Likewise, small leaks around the roof or trunk of a convertible can allow water to drip down onto expensive and potentially hard-to-find electronics.

A quick look at the photo of this multi-channel amplifier and tuner module shows severe damage to the power supply and amplifier integrated circuits in this BMW 650i.

The owner of this Mercedes-Benz GL350 SUV shown above reported that the SiriusXM satellite radio tuner had stopped working. Water had soaked the carpet and seeped into the electrical connectors. A pin broke off during removal because it had severely corroded.

Lee from Motron tells us that vehicles like the VW Tiguan, Jetta, Golf and Passat frequently experience amplifier damage because the units are mounted to the floor near the front of the driver’s seat. Water from melted snow can wreak havoc in a few years. This photo above is from a 2015 Tiguan. Depending on the vehicle trim level, replacing these amplifiers can cost between $750 and $900. That doesn’t include labor to perform the installation and check the condition of the electrical connectors and system fuses.

This 2013 Porsche Boxster had what would be deemed a small water leak. The water collected on the floor under the passenger seat, where it seeped into the audio system amplifier and caused corrosion. Though it might be possible to replace these tiny surface-mount transistors, no vehicle manufacturer provides schematics for amplifiers at the component level. Likewise, the traces on the circuit boards are often damaged by water infiltration. A replacement amplifier could cost between $300 and $500, depending on the trim level of a vehicle like this.

The image above shows what used to be a ground connection for an aftermarket amplifier that was installed in a Kia sedan. The white “dust” is corrosion from the wire that had disintegrated. The shop that installed this amp used wire that contained a lot of aluminum rather than an all-copper conductor.

We should mention that many BMW and Mini vehicles have audio systems that include an 8-inch woofer under one or both front seats. While this might be a convenient location for producing bass in the front of the vehicle, it leaves them susceptible to water damage — the woofer in this 2013 5-series needed to be replaced for precisely this reason.

How To Protect the Electronics in Your Vehicle

Most of us drive our cars and trucks and only start paying attention when something breaks. Few of us have the time or patience to perform regular inspections to ensure that everything is operating correctly. Unfortunately, that’s the only way to catch these issues. A quarterly inspection of the carpet is a good starting point. Lift the floor mats to make sure everything is dry. Check the cargo area in the back to ensure that no water gets into the spare tire area or the corners of the trunk. Look for traces of water having been there and get things resolved before something expensive is damaged.

For those living in the northern states, Alaska or pretty much anywhere in Canada, consider investing in floor mats that prevent water from snowy shoes and boots from getting into the carpet. Companies like WeatherTech, Husky Liner, U-Guard, TuxMat and Advent have vehicle-specific products that collect water, slush and mud. These mats protect the electronics in your vehicle and help keep the carpet looking new — and improve the resale value when it’s time for a trade-in.

As with any accessory purchase for your vehicle, there are some questions to ask about these floor mats. What is their warranty? What does the warranty cover? Are they soft and flexible or rigid? How well do they fit the vehicle? Are there any openings that might cause leaks? How well does the color match the vehicle interior? It can cost a bit to outfit both the front and rear seating area, so make sure what you’re buying is good quality.

Your local specialty mobile enhancement retailer should be able to answer the above questions for you and help you get a set of mats that perform well and look great. If you’ve waited too long or haven’t noticed a water leak, these same shops might be able to help restore your audio system with an aftermarket amplifier or radio for significantly less than an exact replacement component from the dealership.
