My system is basically stock. Oh yea and I have a 12" Xplode and 222w sony amp that I got from my girl. I know sony sucks, that's probably why she gave it to me... Anywho, I'm on a budget and was wondering were to start on my system, with SQ being the goal. Headunit first? Some comps? A real sub? Oh and some advice on which brands/models too. Thanks.
