colossus...now that brings back some bad memories. Can't remember which series it was that I put in once (about 1989-90) but that was one big, scary, unstable amp. Even with the huge (like 7 second) delay, that thing had about 140db of turn off thump. We had it running two Fane 24 inch pro woofers...in a renault encore.

I also remember pulling one out once...power and ground to the amp were disconnected from the fuse/distribution block, and they touched the trunk floor together. The caps in that thing held so much power, the cables welded themselves to the trunk!
