Anyone have a system in their car, if so what do you have/ prefer...also, are you more on the side that systems are annoying, or a good thing? Just figured I'd start some random convo. I currently have a Dual headunit, Boss 1200 watt amp, and a MA Audio 12QS in my S-10, bangs, especially after I put teh polyfil in the box, lows are amazing.
