Amp (system) barely hitting???

[black_sedan 10+ year member]

This is my current setup:

Headunit: Pioneer AVIC-D3

Sub: Image Dyanmics ID12

Amp: JL Audio e1400d

After hooking it up, I can see the woofer barely moving let alone hear it. So I turned my headunit up to 3/4 volume and I hooked up a DMM and I got a reading of only 2volts! What's wrong with my system?

I had a 500/1 and a 10w7 and it was fine, although I did have to set the amp to "low" input.

Is it possible the D3's rca output is burnt? but apparently it still plays notes just very low.

did you set your gains? lol

LOL, of course I did. I guess the rca's doesn't have to be completely out for it to be burnt>?

Ok, I'm back at square one...

I swapped out my head unit for another brand new one. Still the same problem. I made a better contact point for the ground. I also tested the power and ground with a dmm. I also even used the direct input wires instead of the rca's and the problem still persists. I'm beginning to think it's a bad amp?
