Strange problem

[Technomage]

I have a BMW with a HK(harmon Kardon) system, any I put in a kicker L5 15', and a JBL 1200.1 amp, and I have a GSI LOC-2 line out converter, its all connect proper and everything, but theres no sound, it was working before and it just stoped working. I check the sub itself no smoke, and the coil isn't stiff. Whats worng?

take a DMM to the coils f the sub and make sure they still read properly. then check the output from your amp using the DMM, make sure it is still making power. if its neither of those, try your line out converter.

you should be able to buy a cheap DMM if you dont have one.
