U have a bad ground somewhere...did u use a harness between the factory plugs and radio?

No there is no harness just stright wires. So i should reground it sum where else. I was using the ground from the radio.

The head unit should have a separate ground write...make sure that is grounded properly...to the basket of the head unit or good spot in the truck...the biggest problem is not using a wiring harness...that makes sure all wires will be connected that need to...then all u would need to do is wire the head unit to the harness wires...I'd suggest wiring the factory back and buy a harness...the sub would work then as long as you select the right settings for the sub to play...in my pioneer I have 2 settings and one of them will not turn on the sub...the other will...sub out our full....
