    Misunderstanding of head unit wattage

    I have recently bought a car with an aftermarket system. Nothing major. The front two speakers are stock but there is a new head unit and a new pair of 6"x9" in the rear. Everytime i run the radio over 20 or so volume, the stereo cuts out. I was wondering if that has to be a problem with the wattage of the head unit. The head unit is 45wX4 channels and the 6"x9"s are 220 Max watts each, (440 Watts). Do i need a new head unit? if so what wattage do i need?

    Wattage has nothing to do with why its shutting down. It is more than likely a wiring issue, could be a speaker grounding out, incorrect ohm load, bad ground to deck. it even could be a loose fuse in the fuse box but what it is not is incorrect wattage. pull the radio out and check your connections
