A friend of mine is looking to sell me two JBL GT5-12's with a box and a 1200 watt Sony amp all for around $150, would this be a wise purchase? Yes i know the sony amp is pretty shitty but the JBL's and box are pretty nice. Right now i have a Fusion 600 watt amp running 4 6x9's. I still want to run the 6x9's and add the subs. Would my standard car battery and alternator be able to handle this?
