Good Amp for Powering Woofers in my 2000 Porsche Boxster

I'm using this unit to power two 6.5-inch woofers that I installed in the doors of my Porsche Boxster. After about a month of use, I'm pleased with the sound quality. The small size made it easy to find a place to mount it in the front trunk.

Great product

I would recommend this to anyone looking for a small but powerful amp. I paired this with 2 6x9's and the sound is amazing.

Awesome product

I replaced a brand new MTX mud100.2 that was near the same wattage and weighed 1/2 as much for the same size. This thing is 100% as pure as it advertises

Yes All the way!!!

Ive been installing since 14yrs old. I am 50 now. I've always love small kick ass and cheater amps but I truly love plain and straight 2 and 4 channel anps. Ive been around Adcom, USamps, Zapco, Audiocontrol and Denon.This amp is pure love affair. Price and size and quality. My son is an Eagle Scout lots of camping fishing and outdoors stuff using my car and leaving my soun roof open leaves moisture inside but so what its marine grade I WIN. I even got a 5 channel for his car. I might just buy more to install in my garage. I love it so much!!!!

Packs a Punch

Clean sounding small amp. No distortion or engine noise. It does get warm, but not hot. Currently using it to run two 8" subwoofers and a set of tweeters under the back seat of my Dodge Ram truck. Good bass. Nice balanced sound, when using the High Pass (HP) switch option and dial setting about 1/3 up. It complements well with the MB Quart 6x9 speakers in the doors. Highly recommend.
