    How should I wire 2 subwoofers?

    Hello all, I have a general question about how to wire 2 subwoofers to a 2 channel amp
    (please don't knock what I have, i got a very good price on the lot and am not looking for competition grade, just some extra bass)
    2 Sony Xplod 12in SVC 4ohm subs
    1 Sony 2 channel amp rated at 185rms x 2, 400 rms in bridged (cea compliant numbers)


    What gets better results (or rather the pros in cons) between wiring it 2 ways

    1. Wiring them parallel and running the amp in bridged mode (2ohm impedance)
    VS
    2. Wiring each sub to a channel (4ohm impedance on both)

    From what I understand I will lose stereo sound with wiring them in parallel but seeing as subwoofers are omnidirectional I don't think this is much of a loss.

    So what are the pros and cons of wiring them these 2 ways, which provides more volume and response time, and just plain sounds better?

    I'm guessing this has been answered before but I can't seem to word this easily in a search to find results and the rest of the web has been rather useless on the subject.

    TL;DR? whats better, parallel bridging subs vs running each sub off of 1 channel.

    Thanks for the help (and don't rip on my too hard please, first post.)

    You'll get more bass if you bridge them, just be easy on the amp because its not 2 ohm stable.

    Try it unabridged first though, you might get the bass you want that way too.



    "When I listen to a stereo loudspeaker playback in my room and an auditory scene has formed in my mind, how would I know that what I hear is an accurate replica of an auditory scene that could be had at the recording venue? Or more generally, that this is an auditory scene that could have existed at all?"

    Subwoofers do not produce stereo sound(left/right separation). 2 ohms bridged is how I would wire them.

    No its not.

    You didn't say which amp, but most 2 channel amps aren't bridgeable into 2 ohms. I wouldn't do that with a Sony. Shame your subs are SVC 4 ohm. If each sub can handle 400w I'd be tempted to use just one of them bridged. Otherwise you'll have to run them to separate channels.
