    Your 326 is an integrated amp. Tell us how you have the amps hooked up to it. Most would set sub at 80hz

    Yes the 326 is integrated/Pre-amp the integrated is bypassed by the removal of the U clips from "input output" in the back of the amp to make it a Pre-amp!! and using single rca jacks i have 1 rca (left) cable going to 1 275bee and the other rca (right) cable going to the other 275bee.. both amps are in bridge mode AKA Mono block only 1 speaker per amp.. the 326bee integrated amp also has 2 dedicated SUB outputs. for powered subs

    If it were me I'd make both speakers a sub/sat set up speaker. Take the outputs from amp to sub speaker inputs then out from sub speaker outputs to speakers on both. The other way is to go from the sub outputs on the Pre/integrated. This would or should give you full range on the speakers and add sub to the mix. If you go the second route you may need to turn the sub XO all the way up. Try it both ways to see which you prefer. I do not know how the sub circuit is configured in the pre.

    Everything Pittdogg said...yes.

    On top of that like he said earlier as well most people put the cross over to 80hz (I put mine at 100 as my speakers cut off at 90hz). The phase is basically the direction the woofer moves (in then out vs out then in), this is mostly used in case the bass waves from your subwoofer are interfering with the frequency waves put out by your speakers. You can switch the polarity and it in theory should help if the soundwaves are interacting with each other and cancelling each other out or causing muddy noise.

    Want to know the fun part?

    Try it with both subs in 0 degree polarity

    Switch both subs to 180 degress

    Have one sub set to 0 and the other 180

    See which sounds best to you which is all that matters.
