When I bought it, it already had an aftermarket Sony deck and speakers with a 2ch amp. I knew I wanted a sub, but couldn't nail down where I wanted to put it. A couple weeks ago I found a good deal on a box, picked up the amp and sub at cost from Visions and proceeded to tearing my car apart.
Sony DSX S100
Not sure of speakers, want to say Infinity Kapa
Hertz HCP 4D (tiny foot print and lots of power!)
JL 10TW1 (Hits hard for a shallow mount)
On to the good stuff:
Sounds good and very happy with how clean it looks, almost OEM.
