    I want to convert an old Ampeg 6x10 bass cab to a 4x10 and 1x15 speaker cab. 10s in the corners, 15 in the middle, with a new baffle. I have 4 working 10s at 8ohms, and I will pick up the 15 when I can. I would like it to have only one jack like it already has, but am open to adding another if you guys tell me I have to. I normally play an SVT4 through it. Can anybody help me with this? Thanks!

    We need to know the ohm rating of the speakers.

    i would think that they would all be 8 ohms, in which case the ticket would be to:

    1) wire one pair of 10s parallel for 4 ohms
    2) wire the other pair of 10s parallel for 4 ohms
    3) wire those two sets together series to get 8 ohm
    4) wire that whole 4x10 set parallel with the 8 ohm 15 to get 4 ohms total.
    that way, the 15 gets half the amp's power, and the 4 10s get the other half.

    personally, i think it would sound better left as a 6x10, though.

    they are all 8ohms, and yes its for bass. Thanks for the help so far guys.
    I want to add the 15 mostly because I blew two of the 10s last time I put my SVT4 on top of it.
