Question 2000 ford mustang preamp sub problems

I have a 2000 ford mustang with a premium sound system with an aftermarket jvc head unit. I ran into a problem when hooking up my amp and subs in the trunk.
The amp will power on but it barely pushes the subs.
I assumed the amp was shot so I bought a new amp but I still have the same problem.
If anyone can help me with this at all the help would be greatly appreciated.

Info on amp and subs
MA Audio 800 watt 2 channel
2 MTX terminator 12s 1200w peak rms combined 600 rms seperately

how are the settings on the amp? What is the configuration of the speakers to the amp? How do you have power going to the amp/are all connections made correctly and well?

Is it possible that the preamp outputs on the head unit could be bad. There were RCA cables in the back of the unit but they were cut in the trunk when I bought the car

Cut? Its 1 cable twisted you run from HU to amp. =---------= like this, but the connectors in trunk are cut? If so u may just need new rca cable. Its that or as u said the HU pre-amp outputs itself

zzzzzooooooommmmmm
