    I have a Memphis Mojo M3 15'' sub that I'm not using and no one wants to pay anything reasonable for.

    It is dual 2 ohm VC
    1000W RMS
    92dB sensitivity
    .
    .
    .
    I can list more T/S parameter/specs if needed.

    I figure I will wire it to a 4 ohm load, and put a plate amp on it.
    1024W RMS @4ohm: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-808
    540W RMS @4ohm: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-806

    I am looking at recommendations for the size and type of box for it.
    The room is approx. 18'x13' then a bar top into the kitchen. I will be moving in a few months though, so the next room will be a little larger. I'm sure a nice 10'' would be plenty, but I have this and want to use it.

    In my car it was in a 3 cu.ft sealed box w/ 1000W and it was loud.


    So, should I put it in a sealed box, or go with a ported box?
    What size should I be looking at?
    What fequency should it be tuned to for good home bass response?
    Should I get the 500W or 1000W plate amp for it?
    Is there a better deal on an amp for it somewhere that I should look?


    Thanks for any and all info, and sorry for the rambling.

    You will probably want to do a ported box. I have 2 eD 13Ov.2 subs in two separate ported boxes tuned to 20hz. They aren't much for music other than rap but when you get into a good movie they rattle the house apart. They are powered by an Adcom GFA-555 II amp. I would take the ideal ported box measurements for that sub from the manufacturer and build a box and tune it to whatever frequency you want whether you want it for movies or music. Then get either a plate amp or stand alone amp that can be run at 4 ohm bridged. eD LT/1300 will do 1300 rms at 4 ohm for $450. It also wouldn't hurt t look at some of their box designs to base your own on.

    That's not a very good home audio driver. Fs is too high (low moving mass), and vas is too low (loose suspension). Don't waste your money on a 1000w amp trying to muscle this thing. Buy a lesser amp and a proper home subwoofer driver. Put the memphis in someone's car.

    Like I said, no one wants to pay anything reasonable for it. I would rather buy a big amp than totally burn money by giving this thing away.
