Subs won't power up anymore

[reaver18 10+ year member]

I have two 12' mtx 7500 and an Alpine mrp-1000. Everything worked fine up until yesterday. I always keep my back seat down to get more sound in the car. Well, my friend pushed my seat up yesterday, no biggie, I thought. My subs weren't even bumping at the time but I think the car was on. Anyway, he pushed the seat up and I heard a little pop like something unplugged. I didn't think anything of it, but when I turned my system up later, no bumps. I've checked all the wiring: behind the deck, through the car, in the box, behind the box, into the amp. The amp powers up, but the subs won't power up at all. Can anyone help?

did u check fuses?

your rca cables are most likely sliced

yeah I checked the fuses, they're fine.

you know I was thinking the remote wire might have got sliced because it's really really really thin. The RCA cable is pretty thick, I didn't think it would be sliced. I guess last step is to redo all the wiring.

The amp wouldn't turn on if the remote got sliced. I'd check the RCAs before you do anything else.

ok, I'll get new rca's and replace those. I'll go ahead and replace the speaker wire from amp to box also. thanks for the help, I'll let you guys know how it goes.

but isn't it kind of ridiculous that pushing my seat up could have messed up a wire or no?

well my rcas run next to the back seat and if they got caught on a sharp

piece of the car they could get sliced. Just check the length of the wires

and see if there's clear damage done

yeah I did that. Nothing I could notice except one of my zip ties is really tight I was thinking that could be a problem.

Do you have a DMM? I could see this being a lot easier if you could just test what has output and what doesn't.

double check your fuses also, even fuses that look good might be blown. recheck all your wiring too
