Does anyone know, with complete certainty, if upgrading a stereo (deck, speakers, amp) in a 2009 WRX voids the warranty? I've heard from some people that doing anything to your car without it being a subaru part completely voids your warranty.
Hopefully not, I've got
Boston Acoustics Pro 50 for front
Boston Acoustics Pro 60 for rear
Powered by Boston Acoustics GT-4100 amp RSM 100watts x 4 at 4ohms
all waiting in their boxes to be installed once I decide what deck to use. On that note, anyone have any sugestions? I'm looking for best bang for the buck. I don't want to spend 500-1000 if I can get by with a 200-300 deck. Not doing a sub since my 15 month old would go deaf if I added one. lol
