[QUOTE="sampson, post: 1902299, member: 550716"] I didn't know whether to put this in the amp thread or this thread, so I put it here, and also have another thread asking about a blown amp in another thread. Anyway here's the story. Ok heres the deal, picked up a jbl bp 1200.1 for a friend of mine from a guy at car toys, supposedly ran it for like 3-5 months. Anyway, installed it in my car, ran it for like 3 hours on my RE SE XXX 12 on the way home. Ran great didn't get hot, all was well. Got home, installed in a buddies Prelude. He ran it for a week, on 8 gauge wire. I know I know bad shit, but I got him convinced to get at least 4. So he came back today I just ran fresh 4 gauge for him, and then when I put the fuse back in the fuse holder the amp started pouring out smoke b4 it even got turned on. SO wtf? I talked to someone on here, and he said maybe it was an internal short in the car. I talked to a friend of mine and he said that the subs might be wired wrong. The subs were fosgate T1 12's, and I think they might be wired really weird. I check the output and they were 1 ohm each. So I wired them togeather and they stayed at 1 ohm.
