I bought this amp to fit under the driver’s seat of my 2000 CR-V. I had to cut the carpet and padding out from under the seat to clear the seat adjustment mechanisms, but it fits great and the glowing blue rails look pretty cool at night.
I’ve got this hooked up to an Alpine head unit via preamp-outs and driving two pair of Infinity 6020 6.5″ Component speakers. I cannot describe the difference in sound from the old Infinity shallow-mount coax speakers powered by the head unit. The bass is so deep and powerful with no clipping or bottom-out. The highs are crystal clear and not overpowering. It’s hard to tell how much was due to the new amp or the new speakers (since I made both changes at the same time) but I now find myself looking for excuses to drive my car just so I can listen to music. The amp has plenty of features (both low and high pass x-overs and 4x, 3x, and 2x bridging for a variety of sub/sat setups. It is pretty large, but quite attractive, and the sheer amount of clean power is incredible. Highly recommended for loud clean sound; I have not tried this with big subs.

I have owned this amp now for almost a month and I am very happy with it. it is powering two Kenwood 100watt rms 6×9’s in the front doors and two infinity refrence 90watt rms 6.5’s in the rear doors. My hu is a Clarion VZ409 and this amp compliments a great system with amazing sound. it has a set of preouts on the amp that allow you to link to another amp for a sub. i have it paired with a JL audio 250/1 slash v2 powering a 12W3V3-4 and i love the sound. the only problem i had was alternator whine which i fixed with a ground loop isolator. this is a great mid range amp with high end sound and features. i love it and reccomend it to all who want qualitry sound.
