I picked up myself a series 1 2003 VY Calais towards the start of this year and ive done my first mod..which is obviously a new stereo setup
I wanted it to look as stock as possible so I got myself the RCA & Aux input mod by Phreddy sent over and had it installed by wrx884 over here on the west coast. This was a great start as it is still stock for the head unit.
I have a nice system running now
German Maestro CS 6508 6.5" splits in the front
Alpine Type R SPR-69LP 6x9s in the rear
Rockford Fostgate Prime R300-4 Amp running the speakers
2x 12" Clarion subs (not sure of model as it was a freebie)
Older Clarion 400w amp running subs (again not too sure of model number)
I will get up photos of amp mountings as one is under the shelf and one is along the back of the rear seat.
All in all im pretty happy with it, but just need to do a little more tuning.
