Won't push as in it's not powering at all or won't push as in it is underpowering them?

well i have moved the ground wire around thinking maybe its the ground but that didnt do anything different...
all the setting are at the lowest setting on the amp.....
and i cant really tell cuz the other speakers but i think the sub are getting power but nothing like they should be getting so i guess underpowered.......

Well, that could be problem number 1, turn everything to half, but DON'T JUST LEAVE IT THERE
half is a good starting point, after that you'll need to tune it, I can help you a little after you make sure the amp is actually functioning

A big misconception people have though is they think the amp is powering your subs when really the subs are just vibrating from your other speakers.
Normally I'd say it is your remote line but if you say your leds are all showing fine then that shouldn't be the case.
Is your protect LED on if you have one?
My amp is a multi channel and if I disconnect one sub, it doesn't power at all. So maybe check your speaker connections.
Try taking a multimeter if you have one and testing the outputs on the amp and see if you are getting anything.
Try your subs on another amp to make sure it is the amp.
Ultimately if you have power and no output it COULD be an unfortunate case of a blown output on the power supply.
These are just basic things to try..

It could also be wired out of phase, have a case of undervoltage, hell it could even be a bad RCA connection coming from your head unit (it's more common than you think)

Morbid
no just the red over current and the green power light... there are two other lights but i cant read them...
it is a 4 chanel but i did have it working for a little bit the first time i hooked it up with just two of the chanel in use...
bump
the hook ups are all the same i had for my previous amps.. so nothing in the wiring has changed just the amp....

I'm not any sort of guru with audio so the channels not being used and wiring to different ohms and bridging are my blind areas. That's something Bumping can help you with more. But yeah as he said it can be easily just a connection. I'd try a multimeter and see if your amps putting any power out at all.

If you're getting a red light, the amp probably isn't functioning. Can we get model numbers of your amp and what speakers or subwoofers it's powering?

Just a thought, it's hard for me to help if you don't answer my questions  it'll probably be easy to figure out, I just need to know what you're working with first, since every amp, speaker, cd player, whatever, all are different |

yeah that is what mine looks and its 800w
speakers are 10'' sony xplod subs
the cd player is a vr3....
i was out screwing around with it....
looked in side and nothing looked out of place inside....
the i was messing around with the remote wire and got the over current lite to turn off for a second the it was back on... so im guess that it might have something to do with the remote....
