    Well, firstly- what are you trying to bridge and can your amplifier handle the final impedence?

    What subs and VC configuration as well as Re: value for each coil?

    let me know this much and I can point you in the right direction and possibly get a diagram for you to help.

    take it easy,

    my amp can bridge 2 channels at 900 watts which is enough cause my 2 audio bahn subs are only 400 a piece and they have 2 positves and 2 negatives on each of them

    what do u mean by VC conviguration?

    Now you just need Zane to put up a diagram cause I always confuse people when trying to explain how to run a mixed series parallel configuration to get the right impedance for the amp..BTW He still needs to get the rated resistance of each voice coil..i.e. 2ohm,4ohms,3ohm,6ohm..etc.

    im afraid i dont know the ohms. all i know is they are 2 12'' audio bahns... with 400 watts each and they have 2 positives and 2 negatives on each sub... i think the guy that did it last time hooked the positve to the negative then so on.

    positve ---------- negative 2nd sub'' positive -------------negative
    hooking 2 subs together ---------------------


    then he did the same to the bottom ones

    Sounds like your subs are Dual Voice Coil or DVC models. To determine the impedence or ohms of each Voice Coil, you need a multi-meter. Set the meter on ohms (looks like an upsidown horse shoe) then connect the posative lead to the posative terminal of the speaker and the negative lead to the negative terminal of the speaker. The impedence of the voice coil will be displayed on the multimeter.


    From your description, the subs can be wired like this to achieve an impedence that the amp will handle. Pyramid is not stable much at all below 4 ohms, so this would be the best effective way to wire your subs.
