Planet Audio PEQ15 5 Band Pre-Amp Car Stereo Equalizer - Half Din, Subwoofer Output with Adjustable Filter, Fixed Bands, Remote Subwoofer Control

Sceptical at first because of the low price, I was pleasantly surprised after the short installation time. A true parametric, there's a slight learning curve to adjust it properly. This is NOT a graphic EQ disguised as a para! No system noise added and did not have to filter or do an elaborate install. Sub and bass are clean and deep, highs are clean but I wish I had a little more freedom on the top end.The knobs push in and lock, push again to release (found this out by accident) So, once adjusted, you can push them all in for a flush look. Does not have the build quality of the Kenwood graphic EQ it replaced but no regrets. Two things I found slightly annoying: 1 - The knobs are not aligned to true vertical...at their center detent, they are all skewed slightly to the right (12:01 instead of 12:00). When extended, the knobs are off-center in the faceplate and they flex slightly. None of these are dealbreakers unless you must have perfection. For $40, and the significant improvement in clarity and control, I can live with those minor flaws. Highly recommended.

I have a fair amount of experience working with equalizers in professional sound systems. I wanted something that I could use to "tune" the frequency response of my car stereo system. I love the way I can adjust the center frequency for each knob. It gives me all the control I wanted, and now I'm very pleased with the sound in my car.My only complaint is the brightness of the blue LEDs. The angle of my dashboard lines the LEDs up for perfect blinding blue light right into my eyes. I'm going to have to it up and adjust the LEDs.

But these are not very stable. They are easy to tip over, making a mess.

This is the 4th purchase of this little Gem. This time I am using it in my 2013 Hyndai Veloster. Replacing a Quantum QEQ6, not sure if the Quantum is up to the task, but i know the Planet will perform. My music is a bit lifeless with the Quantum, hoping the proven Planet PEQ15, with it's variable parametric versatility will help bring more dynamics to the installation. Could always be the factory radio being a bit lackluster, tho.People tend to bash Planet, but they always perform for me.

Bought a few peq15 for my customers they are a copy of the soundstream mpx4. The thing people must know is this a parametric witch means you can sweep across the secified range eg: Band 4= 4k-20khz you can boost or cut any frequency 4,001hz to 19,999hz. EG: If your car has resonance problems at 6000 hz with a flat tip screwdriver you can tune to this frequency and fix the issues by a boost or cut. If known how to use correctly it can be the most valuable component in youre system. It made my 6.5 inch component door speakers bass just come alive when i sweeped and found the right frequency to adjust.Also thats how bose does there systems they find the right frequency to adjust and preset into memory.With the peq 15 you basically have thousands of bands you can adjust.Build quality:8 of 10. Pros: double sided boards, sealed volume and adjustment pots,film capacitors,seperate sub controlCons: center detent not always in center,could use one more band.

Works well but not intended to be used by the average car audio user. This thing is very touchy and kind of a pain to setup correctly. If you do not know what you are doing as far as freq boost and or gain controls as a middle point. Would not suggest this. Go with a pure graphic eq, parametric has a very high learning curve to get set up right.

Face plate does not align with the potentiometers and switch. Pot knobs are not aligned in the center as stated by others. I can live with knob off centered but off centered knob against the face plate is not acceptable.

works perfect for separating highs, midrange and sub bass
