Default amp turns off after reinstall

alpine ida x100 HU
alpine pdx 4.100 amp

i need a little help here...im reinstalling my amp after i removed all the interior for vibration dampening and sound deadening. i could have sworn i took a picture of how the wires connected to the amp but i guess not. the amp turns on the dims off a second later. where do i start searching? I'm thinking the rca cables are mixed around, i had the 4 wires going to channels 1,2,3,4 labeled so i confident thats correct. I'm going to pick up some new fuses tomorrow as well. any help is appreciated!

It has to be a power issue if things are turning off. Just by the picture I can tell the power and ground aren't as tight as they could be. I'd ditch the electrical tape, only strip about a quarter inch of the power wires and stuff them in as hard as you can while tightening the screws until they won't move anymore...if that doesn't fix it, maybe the power wire shorted out when you disconnected it from the amp and you blew the fuse under the hood, by the battery

alright, i had the electrical tape around the ground and battery so they wouldn't contact each other while i had them unhooked. i just replaced the 30 amp fuses and that didn't make a difference. one thing i remember now is that i ran one set of patch cables on the same side as the battery wire. would that cause an interference? i had it on the other side before so I'm going to rerun that wire on the other side. any other ideas?

It has to be power, sometimes amps will turn on with just the trigger wire supplying the positive power, they won't make any noise, but the light will go on...what about the fuse by the battery
