I hooked up my sony xplod head unit, sub and a power acustik amp. Everything seems fine. I can play my tuner through the sub no problem. But if I choose a different source (cd, aux in) the sub does not work. Why is this? Also my blue tooth isn't working either.

 

you have the remote wire hooked up to the power antena lead not remote lead for the amp hence why it only works with the radio powering up the amp.

 

I was just going to say the same thing.

 

That worked perfectly. Thanks for the help!
