I have a 2000 cherokee limited with infinity premium sound system - I'm wondering if anyone has successfully found a way to keep the infinity amp powering new speakers with a new aftermarket head unit and installed a new amp to power a sub?

I believe the infinity amp is more powerful than the pioneer deck I have: Pioneer DEHX9600BHS CD Receiver with Full-Dot LCD Display, MIXTRAX, Bluetooth, HD Radio Tuner, and SiriusXM Ready by Pioneer
So my idea is to keep the factory wiring and amp in place, replace the head unit with the pioneer, add a new amp to power a sub. Trying to find how I can connect everything properly and came across this on the WJ site: http://www.wjjeeps.com/audioupgrade.htm#AFTER

Looks like there is a special 'OEM1' adapter that might work for this.

Any thoughts/ideas/recommendations appreciated. I'm a car audio beginner, so probably in over my head, but thought I might be able to figure it all out with research.. Do you know of any good sound system write ups on the XJ boards that might help?

Thanks a lot

 

Still working on this?

 

I installed everything keeping the existing infinity amp in place and running a new amp for a sub only. No need to buy any additional connectors. Everything sounds great!
