Hi, im having a problem with sound quailty,I hooked up my player to two amps a 1500bd fosgate for base hooked to the rear rc on the riocar and I hooked a 800 h2 to the front rc . the problem im having is the EQ is not recognizing the front from the back and im getting base thru my highs.Is there a better way to hook up the riocar when using two amps
