    My sub specifications...

    • 12" 4-ohm subwoofer
    • polypropylene cone with Santoprene rubber surround
    • suitable for marine use
    • power range: 50-360 watts RMS
    • peak power handling: 720 watts

    Good match? I know the amp cant push the subs alll the way, but will it still be a good combination?? What is the best way to wire them?

    I would probably bridge it for a single sub. What kind of sub and amp is it?

    The amp is a Kenwood KAC-7204, and the subs are Polk Audio db1240s(single voice coil). I have the custom box that fits under the backseat of my '97 1500, So I will be using 2 subs.

    Do you think they will be a decent matchup?

    THANKS, Joe Money.

    ok, you aren't gonna get the full output from that amp using those subs. Really you should have 2 DVC subs, or 2x2ohm subs to allow for the 4ohms your amp needs for 500W. Only thing you can really do now, is hook up the subs in stereo, and setup the xover and the HPF/LPF to get the least amount of any midrange outta the subs.

    Other option would be to cover and seal one of the holes in the custom box, and just use 1 sub to get the 4ohms you need, and you could see the 500W outta the amp. I believe this would be your best option for the equipement that you have as the 1 sub will see 500w RMS over the 2 subs seeing 170W rms each, and really risking damaging the subs.

    Other option... sell the subs and either buy 2x2ohm subs, or 2 DVC 4ohm subs to get the impedance you need.

    the option with 1 of your subs is your best option imho.

    hope this helps.

    Thats what I was afraid of. Can you point me in the direction of a few subs that would fit my needs?

    THANKS, Joe Money
