wut could b wrong?
wut 2 do?

 

What exactly do you mean? Please provide more info... for example"
1. Is the AMP getting power (considering you are running an aftermarket for it)?
2. Have you tried testing the wires for signal?
3. Have you tried connecting the sub to a diffrent power source (another amp)?
4. Have you tried hooking up another sub or speaker to the same wires?

You get the picture....

 

ya man, what the hell are we supposed to guess what the deal is? it could be many things
