    parallel series help?

    i am trying to wire my 4 ohm speakers into a 2 channel amp in parallel series, the speakers run at 100w rms and my amp runs at 100w at 2 ohm, when i am wiring the amps, there are connections for each channel so it goes like this + - + -, when i am wiring do i just use 1(+ -) connection or do i connect the + into one and the - into the other

    thanks

    you can't run your 4 Ohm speakers @ 2 Ohm, unless you use 2 speakers per channel, which will request a 200watt load. And since your amp is only 100watts @ 2Ohm, you're underpowering your speakers.

    speakers in series


    speakers in parallel

    Just adding more to what was already said. The problem with underpowering subs could cause a blown sub from distortion. What kind of amp and subs are you running. This information will help us guide you in a direction.

    hmmm... is there any other way to run the speakers with the amp, the amp is

    50 x 2 at 4 ohm
    100 x 2 at 2 ohm
    200 x 1 4 ohm bridged

    the speakers are 100w rms and 350 w max imp: 4 ohm

    I think the OP meant just regular speakers like compo's or coaxials.... But other than that.... Yeah, what speakers and amp are you planning to use.

    edit: yeah, you can use the amp if you buy 50watt, 4Ohm speakers, or 100watt, 2 Ohm speakers, or buy a second amp just like it and use 1 amp per speaker and bridge the 2 channels. BUT you're gonna have a hard time setting up both amps equal.

    As long as you stay away from fleamarket brands, cause they will never get their rated output! And one other thing: It's better to overpower a little bit (say an amp with 110watt or so per channel) than to underpower. It will give you more headroom and give just a little more punch to your sound.

    I don't know what your budget is, but this is a nice one:

    Don't know what it costs in the US though. But in europe you're paying €375 for it ($500)
