well i guess its a good thing i dont have a bose system huh lol... or do all a4 come with bose lol

no i think bose is a premium choice thing instead of standard

oh ok good... well then looks like the original owner was cheap... they ordered the winter package but not bose? go figure that one haha... although i think one of my rear speakers has a sub on it.. its big and square looking

Ok so here's a weird story for you, I had this issue on my drive side rear speaker, I superglued the dust cap, let it dry then tested it and everything sounded great, all of a sudden my right side speaker started sounding like crap, the dust cap is secure on it, did I bump something when I was taking stuff apart? I can't figure out where the noise is coming from, it sounds exactly like when the dust cap was loose. I don't here it when I turn down the base so I know it's not really blown either. Anyone has any idea?

i commend you, ive have both the rear subs unplugged thinking they were blown, nope, just a dust cover that is literally hanging by a corner. thanks alot man, as of now the glue is setting, cant wait to hear some clear bass again!


cheers

THANK YOU! 5 of the 8 speakers in my B5 sound like they're blown. i couldn't understand why because i never blast my music. i'm sure this is the problem, i'm going to rip into them tomorrow

All but one of my speakers is doing this. I already had the back speaker replaced twice. I was about to gut the system until I stumbled upon this thread. You're a life saver!

Hey I've been meaning to do this to my car since the previous owner screwed the rear speakers a bit, but how do u remove the plastic covers on the rear deck to get to the speakers?

I tried prying them up a bit and there are no screws I can see so do you know how to take these covers off?

Thanks

^^ my roommate has an e30 325s lol

Thank you very much for posting this. I just recently bought a pre-owned 01' A4 1.8T B5 Quattro and my front passenger speaker sounded like it was blown. I'm going to buy some Krazy glue today and open up on door panel and hopefully this is the problem. Just in case your Bose speakers are blown DO NOT GO TO AUDI (Stealership).
