is the plug for the factory sub under the seat of "most" trucks? like say XLT FX2 FX4? don't want to go looking pulling up the back seat and all that if im not going to find anything............

 

I wasnt aware that there was a sub plug...

 

I would start by looking behind the radio and see if you have the plug. Some trucks only have the dash wiring for the sub, and none of the rear wiring. Some trucks have the whole wiring harness and the rear part is tucked under the seat. Then some trucks have nothing. I fall into the first catagory where I only have the front half of the harness in my truck.

 

thanks thats what I needed
