Review on 🚗 Enhance Your Car Audio Experience with Planet Audio Half-DIN Band Car Equalizer - Subwoofer Output, Adjustable Filter & Fixed Bands by Ulysses Fincher

I bought peq15 for my clients, this is a copy of soundstream mpx4. People should be aware that this parametric witch means you can move within the allotted range, for example: Band 4 = 4k-20kHz, you can boost or cut any frequency from 4001Hz to 19999Hz. For example: If your car has resonance problems at 6000Hz, you can tune that frequency with a flathead screwdriver and fix the problems by increasing or decreasing the frequency. If you know how to use it properly, it can become the most valuable component in your system. It made my 6.5" component door speakers come alive with bass as I swept and found the right frequency to tune into. Also, here's how Bose finds the right frequency for tuning and presetting in memory. With peq 15 you basically have thousands of areas to tweak. Build Quality: 8 out of 10. Pros: Double-sided circuit boards, sealed volume and controls, film capacitors, separate auxiliary controls. Cons: The center detent isn't always in the center, a different range could have been used.
