There’s no denying that electric vehicles are here to stay. Whether we like the way they drive, the sounds they don’t make, or their cost, their popularity is undeniable. Car audio companies like Focal and Alpine have stepped up to the plate with audio upgrade kits for the Tesla Model 3 and Model Y in hopes of improving the performance of these sound systems. Let’s explore several factors when planning an EV audio system upgrade.

Benefit: It’s Quiet in Here

One of the most appealing factors in buying an EV is how quiet the cabin is. The Tesla Model 3 Highland is at about 67 dB SPL at a 70 mph cruising speed. That said, there are quieter luxury cars thanks to extensive sound deadening. Nevertheless, an EV is a nice place to listen to your music.

However, if you upgrade the sound system, a little extra sound deadening on the doors, floor, and fenders will never hurt. As always, look for deadening products that meet the Federal Motor Vehicle Safety Standard (FMVSS) 302 requirements for the flammability of automotive materials.

Drawback: Integrated Infotainment

It’s safe to say that you aren’t going to be dropping by a local car stereo shop to buy a new radio for your EV. They all have reasonably complex infotainment systems, including audio, mapping, and vehicle control interfaces in a single large screen. Adding a high-quality stand-alone source unit to one of these can’t happen without extensive customization.

Your installer can upgrade your car or truck with a new amplifier, speakers, and a subwoofer. However, they will need to invest some time in finding a clean audio signal in the wiring.

Since these electric vehicles are all relatively new, the factory-installed amplifiers will include advanced digital signal processing. As such, your upgrade will also need a digital signal processor. Your installer will have to undo or, at the very least, compensate for the processing already in the system.

Benefit: Good Speaker Locations

Sure, it’s a generalization, but the speaker locations in modern electric vehicles are pretty good. We’ll take the little Tesla Model 3 and Model Y as examples. They have room for three four-inch speakers across the dash and 6.5-inch woofers in the front doors. That’s enough to create quite a concert experience with some aftermarket upgrades. Of course, the cargo space is also reasonable, so adding a real subwoofer is no problem.

Drawback: Limited Power

So, the most significant consideration in upgrading an electric vehicle and some hybrids is that the 12-volt electrical system in these cars and trucks is very limited in its current capacity. Though there might be exceptions, these vehicles have small batteries. The charging system draws power from the high-voltage battery rather than from an alternator strapped to an internal combustion engine.

For context, a power inverter is a device that takes 12-volt power from your car battery and produces 120 volts AC, enabling tools, computers, or other devices to function. Electric vehicles include a different kind of converter. These take the high voltage output of the EV or hybrid battery, which can be 600 volts, then step it down to 12 volts to recharge a small battery under the hood and run the electronics.

The problem for us audio enthusiasts is power. The Tesla Model 3 and Model Y have been reported to have a 500-watt inverter that charges a small lithium 12-volt battery. If you want to run an aftermarket amplifier in one of these vehicles, it will draw power from this tiny battery. Assuming the vehicle already uses several hundred watts to operate, you have only a limited amount of power available for a stereo system.

Thankfully, music is very dynamic. You can listen at high volume levels while the average current draw remains moderately low. If you are an EDM enthusiast or enjoy bass-heavy music, you might be disappointed by the limited power available.

EV Audio System Amplifier Shopping

While sound quality is always essential, maximizing the performance of an EV audio system upgrade will require using amplifiers that are as efficient as possible. We’ve seen several amplifiers that exceed 90% efficiency at full power into four-ohm loads. You don’t want to load the amplifier down in any way, as that always reduces efficiency.

Drawback: High Voltage Electrical System

If you’ve paid attention to the press information on the Tesla Cybertruck, you might know that it operates primarily on a 48-volt electrical system. This voltage would be ideal to power an amplifier if one was readily available. It wouldn’t be hard to create – but they don’t exist yet. That doesn’t mean it can’t be upgraded – it just takes some creativity.

In many EVs, the nominal 12-volt electrical systems operate at voltages as high as 17 to almost 18 volts. Many car audio amplifiers will go into protection mode if they see more than 15.5 or 16 volts. Enhancing these vehicles isn’t easy, but it is possible with proper product selection and skilled installation professionals.

Conclusion

Electric vehicle audio system upgrades are commonplace, as factory-installed sound systems are similar to those in other vehicles. They sound adequate for most people, but enthusiasts certainly demand much more. Drop by a local specialty mobile enhancement retailer today to find out what upgrades are available to improve the performance of your EV audio system.

Whether you’re an audiophile or a casual listener, the quality of your car audio system plays a significant role in your driving experience. From crystal-clear vocals to defined and accurate bass, high-quality audio can make your daily commute or road trip far more enjoyable. But achieving that perfect sound in a car isn’t always straightforward. That’s where a digital signal processor (DSP) comes in.

A DSP is a game-changing upgrade option for your car audio system, offering unmatched configuration and calibration options. Let’s explore the many benefits of integrating this technology into your mobile audio system.

What Is a Digital Signal Processor?

A digital signal processor is a specialized component designed to modify and optimize audio signals before they reach your speakers. By using a computer processor designed specifically to handle real-time digital signals, a DSP can adjust frequency response, filtering, signal delays, and amplitude to ensure the best possible sound quality.

Think of it as the conductor of your car audio system’s orchestra, ensuring that every instrument—whether it’s the highs, mids, or lows—plays in harmony. Whether you have a factory system or a high-end aftermarket setup, the benefits of a modern digital signal processor make it a worthwhile upgrade for any vehicle.

In its simplest physical form, a DSP is a component like the equalizers and crossovers of the old days of car audio upgrades. However, rather than relying on resistors, op-amps, and capacitors to filter the signal, it converts the signal into a digital data stream and modifies it electronically.

Improved Audio Personalization

One of the standout features of a DSP is its ability to let your installer fine-tune your car audio system to your personal listening preferences. For example, they can boost the bass for hip-hop tracks or increase the midbass region to make percussion really stand out in the presentation.

Time alignment—or more accurately, signal delay—is another crucial feature of DSPs. This technology allows the technician to apply delays to the signals going to each speaker so that they all reach your ears simultaneously, creating a more immersive and natural listening experience.

Additionally, DSPs allow for precise crossover adjustments, ensuring that each speaker or subwoofer plays only the frequencies it’s designed to handle. This not only improves sound quality but also protects your speakers from potential damage. Modern, high-quality digital signal processors can apply various attenuation slopes and response curves, depending on the system design and speaker selection.

Enhanced Clarity and Precision

Car interiors are notoriously challenging environments for achieving high-quality sound. Hard surfaces like glass and plastic reflect audio information, while soft materials like carpet might absorb it. In the hands of an expert, a DSP can apply equalization to each speaker to combat these issues. The result is clearer, more accurate sound reproduction that allows you to hear every detail of your favorite songs.

Seamless Integration with Modern Audio Systems

Today’s factory-installed car audio systems are more complex than ever. Decades ago, it was easy to upgrade speakers or add an amplifier and get an improvement in sound quality. Now, factory-installed audio systems use their own DSP to make inexpensive speakers sound pretty good. If you upgrade a speaker or add an amplifier without compensating for the existing calibration, the system may sound worse. A DSP can act as a bridge between these elements, ensuring they work together seamlessly.

Many DSPs also include features like Bluetooth connectivity and smartphone app controls, making them even more user-friendly.

Optimizing System Performance

A DSP ensures that every component in your car audio system operates at its peak. By balancing output levels, adjusting for speaker-to-listener path length differences, and compensating for resonances, it maximizes the performance of your speakers, subwoofers, and amplifiers. The result is a well-rounded soundstage where vocals, instruments, and bass notes are distinct and balanced. Whether you’re listening to a live concert recording or a high-energy playlist, the improvement in audio quality is undeniable.

Common Misconceptions About DSPs

Some believe DSPs are overly complicated or only necessary for professional-grade systems. However, this couldn’t be further from the truth. A DSP in the hands of an amateur can be a recipe for trouble. However, in the hands of a trained installation technician, it only takes a few hours to configure and calibrate even the most complex aftermarket systems.

Tools and Techniques for DSP Calibration

Achieving your DSP’s full potential requires proper system design, component installation, system configuration, and accurate DSP calibration. Professionals always use tools like microphones with audio signal analyzer software and occasionally oscilloscopes to adjust settings precisely. There is no guessing or “tuning by ear.” The accuracy of these unscientific processes is as fabled as the Loch Ness Monster or Sasquatch.

While some enthusiasts enjoy tinkering with their DSPs, consulting a professional ensures the best results. These experts can tailor the system to your vehicle’s unique acoustics and your personal listening preferences.
