1998 ZJ Rear Right Speaker not working

My ZJ had stock speakers in the rear doors that were beyond destroyed, I got new speakers but the rear right does not get power. There is power coming out of the aftermarket radio on all channels, and there is power going into the amp on all channels. There is amplified power coming out of all channels except the rear right speaker. Does this mean that something is wrong with the amp?

Goto the junkyard and pick up another amp, or you can bypass the amp altogether and jumper the inputs and outputs.

https://installeroutlet.com/products...ler-dodge-jeep Here is a kit that is just plug and play, bypasses the amp, if the new head-unit has the power to drive the new speakers.

Are you measuring the rear right speaker output directly from the amp?

If you do it from the door, you probably have broken wires inside the rubber loom that goes to the door.

Out of all the wires in the door jambs on my Jeep, I have only had issues with the wires breaking on the right rear door.. Easy to fix.. just pull the rubber boot back and check...a few in mine were completely in 2.. strip, solder, and tape..

Step one would be determining if you have current to the speaker itself. Measure from the speaker connector itself or try another speaker. If you get nothing there, then of course you are troubleshooting the circuit between the amp and speaker. You can also connect a 9v battery directly to the speaker and see if its working.
If you plug a scanner into the DLC and scan the body, does it show any faults on that rear door?

I tested there is no power coming from the speaker hookups in the right door, no power from the connector in the pillar, and no power coming directly out of the amp for the rear right speaker, I’m leaning towards just going to the salvage yard and finding an amp if possible
