I already have 300watt Pioneer 6 x 9's and a 1200 watt peak, 350 watt rated Sony Xplod subwoofer. What amp should I get that would work best for this setup, and how should I set it all up the best way? The choices are a 350 watt daul amp for 55 bucks, a 600 watt sony amp for 100 bucks..actually thats it lol. Would the 600 watt sound better with my sub? and would it make my 6 x 9's work well?
