Axiom Home Page Forums General Discussion Technical Questions Hooking up the sub

I had the same problem with one of my EP350's. Call Axiom and they will send a new STRAIGHT adapter instead of the right angled one which they apparently have had some problems with. If that doesn't work, then it's probably the AMP itself.

If you have another or can borrow a sub-woofer from a friend, you can verify that the receiver is setup correctly and that will save you some steps.
