I originally bought this amp cause of the low price not because of the amps that it said it hits... Well 6-months later I now own the 4000watt and the 1600 watt stax, and I am crazy bought the amps they really hit the RMS that they say they do... I never have an issue with the amps getting too hot or cutting off, nothing!!!!! I will recomend these amps to any one not only cause of the price but hands down they kick a$@!!! I'm in the middle of purchasing 2 more!!!

Power Acoustik has been a name synonymous with decent quality and good value, and in this amp, it's business as usual. I am currently putting together a low budget system with Power Acoustix as the head unit, amps and subs. I use 2 of the STAX 1600 4 channel amps to actively power all components. I suggest that you consider this line of amps for your next project. Don't get caught up with the big name brands- YOU pay for their big advertising budgets!
