    Default Sub powered by PA500.4?

    I have a spare PA500.4 that I want to use to power my sub MM1040um. How should I connect for maximum wattage on sub woofer?

    PA500.4
    Dynamic power rating 200w x 4 @ 2 ohms.
    RMS Continuous Bridged 250W x 2 @ 4 ohms

    MM1040um
    Peak - 700W
    Continuous - 350W

    The only option would be to bridge the front channels to drive the single MM1040UM sub.
    This is a 4 Ohm woofer and this will give you an output power rating of 200 Watts.
    The rear channels will not be connected so I would recommend turning the gain level all the way down.
