excellent design, built in fan and huge heatsink, lots of power, hooked up to 12W7 and now a Diamond D912D2

none whatsoever!

High power, capable of toying with your 2k watt subs. this amp is well worth the money, even if i did spent the MSRP price for it. try finding an amp that can push as hard with the same power ratings. zapco amps are by far the best makers of car amplifiers.
