sorry if i cant explain it right, im not good with car audio, my friend is the brains. system is a stock mach 460 w/ jvc kameleon deck. subds are (2) 8" esa subs, crap yea but free and temporary. we ran the grounds and power wire but seem to have trouble with the signal. we tapped into some wires that plug into the rear speakers, and we verified that they were correct wires. only one of the subs work, but when you turn it up, you can hear it is distorted, like it is skipping. friend says it is a bad signal, and doesnt know what to do. any advice?
