Only 1 sub working

[L22rules 10+ year member]

Alright so I need help diagnosing this problem and im not sure where i should post but since only one of my subs are working ill post it here.

I have 2 12's in a sealed box but only one of them is working so i thought the other was blown. But when i tested it they were both fine, I then tested my amp but everything is fine with that. I next checked the rca cables because they were old but after getting new ones, the problem was still there. Next i went to my head unit thinking the subwoofer output was messing up and switched it to just a rear output but it still wasnt working. Can anyone help me with this or give me more options to try?

how you know one is not working

Just by looking at it and feeling it. I tested it by switching the wires from the working to the non working

How is the amp wired? 1, 2, 4 ohms? mono/stereo?

Seems to me to be the amp.

Its wired to 2 ohms

Heres my setup:

2 12" RF p3

RF p8002 amp

have you checked the fuses on the amp?

might have a short in the RCA cables

might be a short in one of amps +,- channels.
