what kinda sub and what kinda amp you have

[WhiteStang99]

Probably interference. Make sure that all the wires from the front of the car to the back are shielded.

pyramid amp and spl sub...what shielded mean?

[WhiteStang99]

it means that interference won't bother your subs. Just look for shielded wires or cables when you buy some. They will protect the wire and signal.

Don't run your power and RCA's right next to each other run them down opposite sides of the car.

Check to see if you crossed negative and positive on on of the subs some of them you have to wire in reverse or something.

Make sure your box is sealed nice, I don't know if you made it but if so and you have a lot of air leask you may ot have enough pressure inside to support the sub's suspension and could be damaging it.

Do what whitestang said and check anything I have said that might apply.
Lay off on the bass untill you get it straightened out.

Yeh, sounds like interference to me. Run your rca's on the opposite side of the car, otherwise you get a weird space ship like sound.
