I have a 92 mustang with the stock EQ and stock amp with a Alpine head unit. The sound shuts off if you rev the car above 2000rpm or if you use anything electronic in the car. If you hit the break it shuts the sound off, use the head llights, mirrors, anything. The radio will not work with the headlights on. I tried running a new power wire from the battery and ground but it did not seem to help. Its very annoying. I think its the stock amp but I really dont know. PLease Help. Thanks
