So I installed both by myself and I everything works great except I am not sure whether or not the amp under the seat is working i tried listening and wasnt sure if i could hear it do I have to do anything special to make them work together or is there a way I can test the amplifier. I simply followed instructions of both but im not sure if i need to use some of the extra wiring to make the two compatible

Hey hope you get some assistance. I too installed the pss-23wra to my non amplified system on my 2018 JLU...After, I’m not getting any sound from my speakers. The sub is working. So I did a little test...I’m getting sound from the harness behind the radio, sound from the harness input to the amp, but no sound at output harness of the amp(KTP-445U). Can I say that this is a bad amp with this kit? any suggestions???

I also installed the WRA, used two aftermarket amps and two powered subs. Feel free to message and I can try to help, did the install myself.

I am connecting the PSS-23WRA to X409-WRA-JL now, and I'm not sure exactly how I connect the headunit. Do I connect the t-connector to anything or do I run the wires from the amp/sub directly to the head unit? I appreciate any help.

I figured out that the big T-harness that comes with the PSS-23WRA and connects to the Jeep wiring is not needed when connecting it to the X409.

I tried without the T Harness, but could not get the sub to work. Ugh.
