So my amplifier continues to stay on after the vehicle has been turned off. My temporary solution is to unplug it, which makes the dreaded morning drive to work that much less interesting. I have already tried ordering used amps from eBay, 2 of them, but neither one worked. I need some help on what my options are on getting that fixed. Since I am a novice on auto audio, I will be looking to have a professional installing the solution. Any help would be much appreciated.
