usually when you hear engine noises through speakers, but not subwoofers, when you have cheap-o rca wires running along side the power wire. How are your wires run?

 

check your grounds. Make sure they are on bare metal. Use a dremel to sand down the ground points.

 

the RCA wires are the stinger kind and i dont have them by the power wire i just checked on it to make sure im using a panasonic deck with a RF type r x3 amp and 2 jl audio w3s
