jamie on 19/06/2012 5 star rating

this kick my sub sooooo well for a small powered amp and shakes the car. well chuffed init.

Not just for bass!
MTXman on 11/01/2012 5 star rating

I run 3 of these in my car: two for my MTX TXC6.1 components and the other for my RT12-44 12" sub. Running one amp per side on my comps lets me adjust the gain on each one to balance the power to the system, eliminates any cross-talk between the amps and gives me gobs of power. Plus having 3 mono's confuses people and looks damn cool! Great little amps, nice clean output whether being used for full range of for subwoofer duties.

really pleased with this purchase, this amp easily powers my sub even though the wattage stated is low, its clean true rms power and therefore can power my subwoofer and any other. thanks guys
