i just bought a ground loop isolator for my amp and now its like my amp gets no signal at all. i bought the ground loop isolator because when i would turn my volume to zero there would still be a constant rumble coming from the subs. what could the problem be?
did you try moving your grounds for the amps and HU before you bought the isolator?? they usually aren't needed, a simple ground location change will usually always solve the problem.
i also haven't heard of anyone even getting thoes isolators to work at all, lol.
