I have a Pioneer AVIC F700BT in my 97 SC300 and I ran all new wires and replaced the front and rear speakers with aftermarket set, but since I bypassed the amp the is not going to work obviously. I'm curious could I use this cable and connect the sub directly to the Sub output on the headunit without having to buy a aftermarket amp? http://www.radioshack.com/product/in...ductId=2102959

 

yes, they'll work.
