Bought the Alpine headunit and the four infinity door speakers from best buy and installed at best buy.
Recently bought the Pioneer 800W Amp / 2 8" pioneer shallow mount subs / custom made box to fit behind back seat of DC, all from a fellow TW member for $320 with shipping
Had everything installed at Audio Express home of the $200 install which included wiring kit/ install/ labor fee/ warranty
It sounds great for my taste. Not going to win sound competitions but gives a great bass sound thats perfect for me.
Here are the pics
