I installed a Kenwood head unit so I don't need these anymore. This adapter makes it easy to install an aftermarket amp to your factory stereo. It has 1 set of RCA's and ties into your factory radio harness. 6.5 feet of JL audio harness cable. My amp is under the drivers seat and it is plenty cable to get you there but not to the back of an extended or 4door. Starting at 35.00 shipped. Let me know if you want a pic, I can text or email them.
