well i had this problem before and i thought it was the amp so i got a new one. well it worked for awhile and now its back. it will work for a few second to minutes then cut out and back and forth. i unplugged the amp so i dont mess it up nor the speakers but does it sound like a short maybe? i noticed a pretty loud noise coming out of the speakers, well i think the speakers, when i put up and down the vert top. its pretty loud and im almost sure its through the speakers so would an electrical current cause that noise? i had so many problems with my old 95 gt that i dont want this one to start falling apart on me to. is there a way to check for a short besides checking every inch of wire to see if there is a break in the line?
