WORTH THE MONEY!!!

I bought this to run my kicker RS 6.50 and two other cheapo speakers. This thing kicks @SS!! My rockford fosgate amp overheats before this one does. IT HAS NEVER OVERHEATED ON ME IN THE 100 DEGREE CALIFORNIA WEATHER WITH NO A/C IN MY 240SX. This was the first power acoustik product I've ever bought and now I'm all about it. I only look at Power acoustik when it comes to amps now. Worth every single penny. I want a PS1-2000D now to run my 15in kicker L7 because my rockford amp just isn't doing it for me.

Nice Amp

I have this hooked up to a Jensen 9312HD unit pushing my factory Dodge Infinity speakers. It actually sounds good. Nice Amp, good adjust ability, excellent price with fast shipping.
