Aftermarket Stereo

[2007]

I recently installed a Kenwood doubled in screen in my 2007 4runner with the fac tory JBL system in it with factory amp and subwoofer. I was wondering how to get the factory amp and subwoofer to work with the aftermarket stereo, and how to connect the center JBL tweeter to the system since aftermarket stereos only support 4 speakers. I bought the correct harness and stuff just cant seem to figure those two things out.

If those aren't working you didn't buy correct parts. There are special harnesses for jbl equipped 4rs. Stop by your local shop or try online to find.

You need to get the PAC adapter that works with JBL amps, and my JVC double din is identical to the kenwoods and it has a setting to allow for center channel
