What gauge power wires are you using?? What amps are you running? Do you have a capacitor?
Cause if you have less than a 4gauge wire you don't have sufficient amperage going into your amps...if your amps are shitty it's going into protection mode because your gain is way too high!! But if you have atleast a 4gauge and have a good amp! Then you might wanna look into getting a capacitor
