I have a 2011 WRX Sedan that I have delighted in driving all summer long. I have zero complaints about the car except the lackluster stereo system. I have looked and looked but can't make any decisions on an in-dash and speaker upgrades so I thought I would look to my fellow Rex owners. Does anyone out there have an aftermarket that they love? Or speakers they would recommend? Also, does anyone else experience rattling in the doors with the factory speakers? And if so, any solutions? Thanks in advance!
