Here are after-market additions to my 1989 Acura Integra RS

*Sony CDX-4875 CD player single DIN -- $180
*Infinity Reference 5.25" speakers -- $60
*Pioneer 6.5" speakers -- $60
*Optimus 200W amp bridged to 1 channel (Radio Shack) -- $99
*Pro Series 200W RMS 12 inch sub (Radio Shack) -- $40 [Same specs as MTX3000 subs]

A loud and clean system for under $500 =)
I did installation of everything except the CD player myself, so that saved a good $80. I also had a professional carpenter I know make the sealed box for me, so that was done as a favor.

What do you guys have in your car?
