Sub is tapping

So I wired it all up and it sounds really nice. Still got to finish coving the box. Sounds good and everything untill I start the car. Once running the sub started to tap. It does that constantly while the car is running. Im pretty sure it did it while the car was off too but I cant remember form being in a hurry to get to work. Once I got to work I just ripped out the remote wire becasue I didnt have any tools to take it out. But do any of you have an idea of what the tapping was?

I`m gonna take a stab at this. Sounds, maybe, like a bad ground some where and/or alternator whine. Where are your RCA`s routed? Are they routed along with your power cable for the amp? What is your headunit ground like and your amp ground?

Ok here is how it is ran.

power wire is ran through the firewall on pas. side.
It is grounded on the bolt that holds the back seatbelt on.
Remote wire is ran up to the front to the HU with the power wires.
RCAs are ran up the middle, around the sub, and then ran through the back carpet to the amp.
The speaker wire is ran from the other side with the amp along the rca plugs.

Could possibly be cheap rca`s. Can`t really tell because we don`t know everything about your system. Why don`t you post up all the different components you have.

what size is your power cable and your ground cable. I never liked putting the ground on the seat belt mount like that. I prefer to mount it in it`s own spot.
