My S3's bose set up is aving a few problems... I have an after market headunit ( alpine dvd ) and have added an JL audio sub The problem is now that, the speakers in the drivers door , The tweeter is not working and the mid speeker lower in the door sounds rough. kind of scratchy if that makes sence? So im thinking i need to change the speakers AND maybe it an after market amp. What is the maximum speaker depth that will fit behind the standard door pods?
