my friend has a '91 civic wagon. he just bought 4 kenwood speakers for $100 (on sale at bestbuy ). the 3-in-1 with tweeter, mid-range and woofer i beleive. 55rms - 220 top. Now hes looking for a headunit and amp. What are some good not too expensive head units and amps. im asuming he wants at least an 880 watt amp to get his speakers at full blast and maybe a small subwoofer later. But if the deck ahs bulit in amps he doesnt need as much i guess but who knows. any1 got any suggestions? amp - cheap but stillgood quality. and head unit - less then $200 and its gotta play wma and mp3 format...any got any suggestions?
