This is a very dangerous item ... way too small wires for the amps !!!! only 1.5mm2 wires for 600W !!?? are the guys doing that serious ? After only 10 seconds the wires burn , if you want catch fire in your car this is the perfect item AND : VERY poor finish (not all same screws everywhere) spray can paint over some bolts and sticker Anyway unusable ..... direct in the trash can sadly
