Review: ...money well spent... - I'm VERY satisfied with this 2 Channel amp. I had the 4 channel model of this amp and it would overheat after maybe 20 - mins of use. I switched to this 2 channel amp and it so far hasn't overheated not 1 time yet. I'm sure that we don't truly get 4,000 watts out of it but for the money spent, this is one of those rare cases in which I can honestly say, it was money well spent. I have had several amps over my 38 years in life and, this one so far is one of the better ones simply because it doesn't constantly shut off.
Review: Worked amazing paired with Pioneer Champion series subs and 0 guage ... - Worked amazing paired with Pioneer Champion series subs and 0 guage wiring kit. Small overheat problem, automatically shuts off until it can cool down then kicks back on. But then again I may have just been pushing my subs. Nonetheless, amazing power from this amp. Great price and great quality
