the problem i am having is that only the tweeter part of my coaxil speakers are working. I dont know if it is a problem with the speakers, HU or amp. Any suggestions?
Sounds like a connection problem to me. If you got them installed somewhere, just go back and tell them the problem, or if you did it yourself, just go back and double check all of your work. It's possible that you blew them too. Go with components next time.
