    P.S. when you're running an amp bridged that's how you're supposed to wire the inputs anyway (split from the same output signal). it's a bad thing to have two signal sources feeding a bridged sub. check your amp's manual, it will probably tell you the same thing

    In my home theatre setup I had trouble with my bass also. I figured out that the center and sub come out of the same jack and in my software there is actually an option to switch which side gets which signal, so instead of having to fiddle around with the wires I just checked the box. You might want to look into that, too.

    Maukio, what software are you talking about?

    The following configuration will give you bass if everything's hooked-up correctly.

    1. 5.1 sound - (I seem to vaguely recall an issue with the LFE channel being cancelled out by the way the Audigy mixes the channels to create it in 4.1 mode. I'm not sure if this effects you, but you might as well be safe by setting it to 5.1.)
    2. Bass redirection
    3. CMSS
    4. Stereo Surround

    If you don't want your bass "redirected" (ie: you want it going to all your speakers), you can turn off bass redirection and connect the center channel to your sub. In this case you must use the crossover in your amp. But you'll at least have control over the volume of your sub in software.

    Also: You need only to connect one of the inputs on your amp if it's bridged.

    ok, so I need to only hook up 1 RCA to my bridged AMP correct? Its a stereo plug from my center/sub out on my audigy. I do not need to split this to teh two RCAs on my AMP? The amp manual does not tell me what to do.

    Yes, only one RCA. The output of the amp in bridged mode is a mix of the left and right. Whatever you plug into either one you'll hear though both speakers. So just plug either the Audigy's LFE or center (depending on which one you want to use) into one of the channels on the amp.

    I actually split the single RCA into a y adapter as some have done. The sub sounded real good with one RCA plugged in but now I have the y splitter on the red cable and MAN, it thumps even more. I have yet to really give it a test but I think it works better. thoughts? I have the Amp bridged 100x1 @ 4ohms to 2 MB Quart subs.

    It is probably still taking stereo input. Meaning with only one RCA hooked up it is only recieving half of what it thinks is a L + R signal. By splitting the mono into the two RCAs you are giving it twice the signal into both L+R inputs now.

    If it works, great. Did you get the cmss settings to work? Does it reset after resuming from standby for you too?

    There is no such thing as stereo in bridged mode, only two mono inputs (and one mono output). Turning up the volume of the LFE or center channel on the Audigy would accomplish the same thing.

    Either way, if he is getting more sound by plugging both rca cables into the L+R inputs, then something isn't as described. It seems counterintuitive for the amp to take both inputs and use them in bridged mode, but I guess that is possible and probably what is happening. In which case, either way works, it will just depend on the signal strength with one vs 2 inputs and what level you desire. Correct?
