Setup kicker 12" L3 on kicker zx300.1. Received a modded linear 952iq for my wifes old school build. Decided to tey it out in my car. Swapped wires over, wiring for bridged mono on the amp. Powerd up and bass was really great for about 15 seconds then sub basically "locked up" on a note. Shut everything down and restarted with same result on different song.

Possibly wired wrong? Internal amp damage? Any ideas?

The sub hit a low note and just continued to play that same note even though the song continued on. Mids and highs moved on and sub stayed on the low note
