Just picked up a Clarion apa 4203 4 channel amp. It was on Craigslist for 30 bucks so i grabbed it, didnt know much about it but i figured for 30 bucks it was worth a shot. Anyone know anything about this amp? Its pretty beat up but nothing a nice paint job cant fix. Its rated at 50 watts @ 4 and 75 @ 2, any idea if these are some what close to actual power? Its fused at 50 amps. Any input on these would be nice.
