Little Rock, AR

Very pleased.

January 30, 2011

I picked up this part when replacing my stock 2003 Ford Explorer Sport Trac stereo with an aftermarket JVC stereo. My stock system was a pioneer 6 cd disc changer with 4 speakers and an 8 inch subwoofer. Contrary to the schematics I found online though for my particular stereo, my front speakers were not powered.

This part fit the bill perfectly.

Works perfectly as described to hook up the factory sub in my 02 Mountaineer to an aftermarket deck. Simple plug in using this, no hacking required to use the factory sub.

I got the connector for a "complete" install, even though I left it unhooked at the moment... not much point with a W7 in the back.

do you have the reverse of this plug? I want to use my oem radio into an aftermarket sub
Mike K on Aug 12, 2016
Best Answer: Hi Mike,

No such plug exists. Instead, you must consider a Line Out Converter. Call our sales team for help with that.
