I got this amp from circuitcity, before I knew about onlinecarstereo. It's serious! I had it powering two kicker 10" comps, and they didn't do the amp justice (too much power for them) so i got a Jensen 12" dual sealedbandpass box 400rms and the amp stiLL overpowered them when set to 2ohm config (speaker sounds distorted when amp was set to high levels). When this amp is just set at half mass it performs!
Also the lighting effects are nice, it can illuminate the back seat to the beat of the music.
