i my opinion,its better off to just save some money and pit a whole new stereo system in your G.my set up consist of:
clarion max 2256 head unit w/ tv monitor
2 sets of crystal components door speakers
clarion tv tuner
clarion vcr
clarion 12 disc changer
rockford fosgate 4x400 amp
rockford fosgate 1x1000a1 amp
2 12 inch kicker solobarics
clarion EQ
1 farad capacitor
and a PS2
good luck on your system
i guess its obvious that i voted for Clarion.
