Great value

I have this amp pushing 2-12" Duals in a bandpass box with a 500K Scosche capacitor and it sounds great- better than my RF 201s. i would recommend this amp to a beginner or even an experienced car audio fanatic, especially for the price.

the true review

I'm a sound system installer and my wife wanted this low grade cheap amp, well I installed it for her on an 8" kicker cvr 4 ohm and it turned out to give that little bit of depth and still hit the subsonic highs and lows. overall it is a good amp to start out with.
