    If anyone can help me please let me know. I have two powered speakers that takes (ac 120v 50-60hz 108va max) each and one subwoofer that takes (ac 110-120v 50-60hz 100watts) I need a power inverter to power all three of theses appliances but I don't know what kind of inverter I need. If it helps I'm installing it all in my boat with 3 deep cycle marine batteries.

    Total power is 300 watts. It's either 12v dc or 24v dc to 110v AC @ 60Hz, depending on whether you have 24v or 12v dc in your boat. At 12v and full load your current will be around 25A. Such a system with the sound turned up can fairly quickly flatten your batteries.

    i agree, unless the boat's motor is running.
    Your boat needs a 120v inverter that supplys adequate wattage to your system, so if ur system needs 300 watts, then put in a inverter at least 1.25x the required power.

    So would a 700w 12v dc to ac 120v 5-15R 3 outlet power converter work?
