I really appreciate your help. I don't exactly trust my local audio place. I took her into replace my aux input being that I have to adjust the cord every five seconds to have all the speakers that do work play. agreed on a price, then about on hour later got a call that I needed all new amps, which would be 1000. I told them forget it, and came in to get my boat.They tried charging me double what my quoted price was for the aux input. They did not even replace the aux, all they did was tell me I needed new amps. They wanted to charge me 200 so i hope they bench tested the amps. Got to my boat, and none of my audio worked. no tuner, no CD, no aux. went back in and they said i had to sign a paper for them to hook my amps back up incase they all go bad tomorrow its not their fault. Unfortunately their the only boat audio place around. Just went to the boat and checked my amps. The one running the single sub is a JL G1300. I didn't see any labels for the marine, but took a pic.
We are the second owner of the boat so i suspect the previous owner had some we things in there that could have possibly gotten to the amps. If you have specific JL amps you would suggest I would love to hear them.
