General New 9-3 Posts and Information
Looking to make some mods to my 06 9-3 2.0T. Looking at flashing ECU, stage one and two, but first I wanted to tint, and also install a sound system.
As far as sound system, I want to replace interior speakers, and one 12 or 15 in the trunk. Budget around 3-4 bills.
Do you guys...
