One of my woofers is popping and I was wondering where I stood with warranty and the Alpine update. I have an extended warranty though, so not sure how that will affect things.
I think the L7 subs are the way to go though as they're the same resistance as the standard ones.... expensive though. I wonder if BMW, if they agree to replace under warranty would allow you to pay the extra and get L7? I doubt it.
