Help me troubleshoot

[AConnelly09 10+ year member]

Moved my Alpine SWR1242D and MB Quart DSC1000.1d from one car to another. (it worked fine in old car)

HU is Pioneer DEH6300UB.

I ran my wires, fused near battery, etc, but for some reason my sub won't hit.

My amp has a remote bass knob via cat5 and when I plug and unplug it I can hear the connection in my sub, but it won't hit otherwise.

I'm grounded to a piece of metal in my trunk using a self tapping screw, it's tight. I've quadruple check my speaker wire (12 guage I believe) from my amp to box, even swapping for brand new wire. I also double checked the connections inside the box.

My amp is getting power. The protect light is not on. I've adjusted all of the amp settings (even though they were setup just fine before).

I don't know where else to check, or what could be causing the failure.

Hopefully someone has some ideas.

What option would I go to on the HU to make sure the RCA out is turned on? I've cycled through the audio options and made sure they all made sense.
