UPDATE!!!! I have an Avatar cab with multi ohm inputs on the back, two 8 ohms and one 16 ohm. I've always gone 16 ohms from the roadster to 16 ohms on the cab. I decided to try 8 ohms to 8 ohms and everything works perfectly now??? What is messed up, the cab or the amp? 8 ohms from the amp to 16...
