This is a faulty product! It caught fire in my truck not hooked up to speakers even! The positive screw is too short and doesn’t hold the PowerLine in it must of wiggled more and more over time and finally made a spark and caught a flame inside my truck! Professionals hooked it up. And professionals told me it had to be the short screw not fully locking on the power wire that started the fire! And now I can return it because I didn’t hook it up rite away in my truck!
