If you want a real solid quality amp. Then try this amp. Its a Cresendo Audio 4 ch amp 125 watts rms at 4 ohms. so its a 1000 watt peak 500 rms total amp. Its a Zenon board, which companies like JL audio etc use. Only the really good quality companies use this board. its a little pricey but you will not find clarity with this power with a 4 ch setup for this price or close....
