Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

    Best performance question re: Amp wiring

    I got a Pioneer GM5300T (On Newegg) for Christmas, and I'm working on getting a decent system worked out using that.

    for quick reference, the RMS specs of the amp:
    RMS Power
    125W x 2 @ 4 Ohms
    190W x 2 @ 2 Ohms
    Bridged Power 380W x 1 @ 4 Ohms

    I'm currently thinking about getting two 2 Ohm 10 inch subs in a sealed box (really, two 4 ohm DVC subs wired to 2 ohm).
    The reason I want two 10s is because two tens sound better than one 12 (in my opinion)

    Now, I have a question on the best way to wire the subs and amp. As I understand it, my two options are to:
    1. Wire the subs in series and bridge the amp, or
    2. Run each sub on it's own channel.

    Is there a benefit to running one way or the other? Wattage wise it would seem to be equal.

    I know it's not a serious power system, that's not a concern to me; I'm just trying to fill in the low end with quality, not quantity, with what I got.

    Also, my car is a 1992 Prelude S.

    Thanks guys!

    The amp may run cooler bridged at 4 ohms

      And you might want to check and see if that amp is 2 ohm stable. If not, you'll have nothing but problems. It'll overheat and your amp won't last long.

      And 2, dual 4 ohm speakers, you can run them in either 1 or 4 ohms as a pair.

        The amp specs sheet has a rating for two ohms, so I would assume that it is two ohm stable. Is there any other way to check?

        By your second point, I take it you suggest bridging the amp and running both subs on one channel? That diagram utility is pretty cool

          2ohm stereo and 4ohm mono is what the amp is rated at
          Having a small cam is like having a small dick every time you go to use it you wish it was bigger.

            BTW 4ohm mono runs cooler than 2ohm stereo and even if you got the 2ohm svc speakers I would run them in series and then parallel to the amp hope this helps

              If I'm not mistaken, and if I am, someone correct me if I'm wrong. 4 ohm mono is the same as 2 ohm stereo

                This amp could run 4 ohm stereo as well, though, so I don't know if you could call that a rule. Wouldn't it depend on if the amp could run 2 ohm?

                  Don't think so. 2 ohms is still a lower impedance bridged or not.
