So i have a crunch pza 1400.4 being used as a 2 channel amplifier for 2 kicker cvrs right now and i have a very weird problem. if i turn my car on to where just the radio is on and the engine is not started everything is fine and it all runs normal, but when i turn the car all the way on the subs then recieve a constant signal from the amp which eventually throws it into protect mode. i cant figure out exactly what the problem is since it works when the engine isnt running but does not work while it is running. any suggestions of what i should do? and dont suggest an upgrade because i will be doing that in a few months anyways and have the plans already worked out.
