Question about MTX Thunder 404 Car Audio Amplifier
Are you trying to hook up the subs while it's running? If so a spark would be expected because that's a lot of voltage... (and not a good idea). If you mean when the amps OFF, then the output is shorted to the power supply and the amp is in serious need of repair.
