I think I blew a Bose Speaker
 

For the last 6 months i've had an on and off popping sound from my door Bose speaker. It's comes for a while then goes away. Now it seems like it's back for good. Is this something I can replace myself, i'm not the handiest person in the world. Should I be looking at upgrading and if so to what? My car i 07 C2S.

Its not that difficult if you're comfortable taking interior panels off. I got mine on eBay and followed instructions on removing the door panel found on the forums. Half hour job at most, can look up the link if you're interested.

Would Suggest budget audio install tips of ryem3. You won't regret it. Since your there already might as well go for the speaker swap instead of going back to the awful so sounding bose speakers
