I have a Microair 760 that I installed in my ASW20 that didn't wire up like the instructions. The cabin speaker leads have 12v on them, burned up a new speaker. The only way I can use it is with a head set because if you use a boom mic I get bad feed back. I installed one in my LS1 and it worked perfect. Is there any support in the US that I can talk to or send it to have it looked at?
