So I finally decided to upgrade the sound system in my BMW, and I went out and bought a JL 500/1 monoblock amp and got an Alpine 2ohm/2ohm Type R 10" sub from a buddy of mine (500Watt RMS, 1500Watt Peak).

Anyways, I brang it to a shop here in town to have it all "professionally" installed.

The guy used a line converter because the rear speakers were tapped because I wanted to keep the factory head.

I told the installers to make sure they do an amazing job, because I want a high quality install, and I'm willing to pay for extra hours just to make sure an amazing job gets done. I told them I wanted everything tuned perfectly for SQ, and not SPL.

Anyways, 3 days after the install, the subwoofer blows on me.

What should I do? How on earth did this happen? Should they pay for a new subwoofer of the same value for me? I never touched any of the settings.

I have a feeling they had the Input Sensitivity on way too high, because when I had the music on really low, the subwoofer was pumping pretty damn hard for barely any music! Could that be the problem?

Stock head unit = massive loudness curve. They probably tuned it "right", at full output of the deck, but as soon as you turned it down, the bass got cranked.
Then you put some bass heavy material in, and poof! The factory smoke escaped.
Good luck with getting a new woofer. Now spend the cash on a Clean Sweep, or change the head unit.
Probably should find a better installer too if they didn't tell you it was the wrong thing to do.
Sorry.

A clean sweep eh?

Are you sure that they just didnt set the input sensitivity too high?

If you want to upgrade from a LOC and think the clean sweep is to expensive then check out a Re-Q. Its about $120-150, complete with a subwoofer and speaker amp RCA out and gains for both. I have one in my truck because i could get the Re-Q for 120 or the CleanSweep for about 350 and i read a couple reviews on the Re-Q and it did really well so i decided it would serve me fine. Not as good as my old Alpine 9831 but it still sounds 100 times better than stock.

was it not a used subwoofer that you got from your buddy? If it was, maybe it was already damaged? If I was a shop I wouldn't be replacing a subwoofer you brought to me, I'd have no idea where it had been or what was done to it. If it was new, you're probably still out of luck as it was not purchased from them, and they'll more than likely claim user error. As far as correcting the problem, get an aftermarket deck. For the amount you'll end up spending to get the factory one to sound decent and perform properly, you can get a good aftermarket unit.
