I saw a Clarion APA450 amp on ebay for about 100 bucks shipped and it sounds like a good deal. Its 50Wx4 RMS. You guys think this amp is any good for pushing my interior speakers? Right now I have some Pioneer 4-way 6x9s and MB Quart Discus 2-way 4"s. Or maybe you guys know any other decent amps I could get for 100 bucks or lower. Any input is appreciated. Thanks.
