crunch amp circuit fix

[aespino88]

hello guys i've been trying to fix this amp for awhile now and i can't seem to find the problem. its a crunch powerzone p125.2. turns on and does not go into protection. i know everything is connected correct so theres not a power, ground, or remote wire error. i opened it up and theres nothing burned or no sign of something come undone or loose. i also checked the mosfet transistors and they all seem to be fine. i've also checked the rca plugs and it does get audio signal but it doesn't send any to the speaker terminals. i used to have it connect to 2 mtx 12s (it sounded pretty good too) so i know it works. but its been a few months put up in the garage and now it doesn't want to work. if somebody could help me with some step by step troubleshooting or tell me other things i should check i would really appreciated. thanks
