there is a guy local selling an infinity kappa 102a amp rated bridged 300 x 1 @ 4ohms. he had it hooked up to a punch xlc 8ohm 200rms oldie, had it wired parallel bridged. that setup would not have harmed the amp at all just the sub right? i have a chance at getting that amp for around 75, and want to know it would still be any good to get. holla back ya'll.
