Showcasing the Best in the Mobile Enhancement Industry
Once again, we approach a discussion of the laws of physics and how they affect the electrical systems in our cars and trucks. The enemy of all power transmission systems, be it the battery and alternator to the amplifier in your vehicle or the nuclear power station or hydroelectric dam across the state to your home, is resistance. I saw a power wire sizing chart earlier this Read more
Every few months, I learn something that, had I put some effort into thinking about it, would have been obvious. For example, my friend Andy created a Facebook post a while back, asking why people thought amplifiers needed fuses. They will tell you it’s to protect the amp from damage. That’s not incorrect. However, the scenario where fuses are necessary is very different from Read more
Efficiency is defined as the ratio of the power or work consumed by a system compared to the work done by that system. In the car audio industry, we typically talk about efficiency in the context of amplifiers. The best amplifiers consume only a little more power than they provide to a speaker or subwoofer. Low-quality solutions consume extra power and convert that into heat. I Read more
When it comes to ensuring that your car audio amplifier is making the most power possible, nothing is more important than properly sized, high-quality power wire. Can an amplifier produce 2,000 watts of power if fed with 4 AWG wire? What factors affect the size and quality of wire needed for an audio system? There’s a lot of confusion around wiring, so let’s look at some Read more
In late September, I got a call from a friend asking if I had any connections to purchase some new fuse holders for his car. The car is a fourth-generation Toyota Supra with a single-turbo kit and an AEM stand-alone engine management system. Unfortunately, it seems the fuse holders that fed the dual Walbro 255 lph fuel pumps had failed, leaving my friend stranded on the side of Read more
We were recently at an event that was hosting a mobile audio system SPL competition. If you aren’t familiar with this sort of thing, it’s a contest to see who has the loudest stereo. We aren’t talking about cranking the dial on the factory radio. Instead, some of these folks build steel and concrete reinforced subwoofer enclosures and feed tens of thousands of watts to their Read more
Adding a subwoofer to your car audio system is a great way to improve the quality and accuracy of the music you hear. As we’ve explained many times, sending bass information to a dedicated amplifier and a larger speaker alleviates the need for the small speakers in your vehicle to work hard trying to reproduce low-frequency information. The result is that the smaller ones sound Read more
Specialty mobile enhancement installation technicians couldn’t upgrade the audio systems in our cars and trucks if they didn’t have access to high-quality, correctly sized wiring. Whether they are connecting a pair of speakers to a radio or running large power and ground wires from a battery to an amplifier, wiring and its size is crucial. There are a lot of myths and Read more
