Apologies ahead of time if this should be in the Audio Forum, but this is a technical questions.
I asked the same on E46 fanatics and haven't had much luck. I just installed the stage one system from BAVSOUND on my coupe. My symptoms before install were the passenger rear tweeter was fuzzy and the rear midrange (deck) did not produce any sound. Upon installation, neither produce any sound though the rest of the speakers work well. I checked connections. Per one user on E46fanatics my amp was going out and I should replace with a used factory unit. I did and installed and I still have the same problems. Is this a headunit now or something else all together? The only aftermarket install I have audio wise is a basic bluetooth audio streaming device through the headunit.
Any guidance or help is appreciated.
Thanks
