Searched before posting, could not find any threads.

Have a 2019 JLU Rubicon with the 8.4" with Sub. The sound is left to be desired. Looking to update the speakers and possibly adding an AMP. Would like to keep the factory 8.4". Has anyone accomplished this?

Thanks,
John D.

I did see some of the other threads, none dealing with the 8.4" and sub.

yes, pac-audio makes an interface (AP4 CH4, 1 I think that is the number) that plugs in between the factory radio and the factory harness that allows you to plug in RCA's or even fiber optic to your amp. It doesn't require cutting of any stock wires.

Does this bypass the factory amp? I want to upgrade the speakers as well, and the sub speaker.

no, there is a little jumper that needs to be connected to keep the factory amp getting signal. it still works. Replaced my front speakers and ran new speaker wire for them from my jl amp. still using the factory amp for my roll bar speakers.
