Thread: amp wiring

  1. #1

    Default amp wiring

    hi there, one of my amps is 225 rms x2 at 2 ohms. the amp is 2 ohm stable. what is the best way to wire it to 4 tower speakers that are 200 watts each 4 ohm.

    thanks

    Good news: One pair (2 speakers) wired in parallel (+ to +/- to -) to each amp chnl. This will give you a 2 Ohm load at the amp so it will deliver it's rated 225 watts rms. Not so good news: That 225 gets divided by the 2 speakers wired to each chnl. So basically, your speakers that are rated at 200 watts rms will be receiving 112 watts. In general, that 225 watt spec is also more then likely at 14.5 volts, so that number is likely to drop when the engine is off and the battery voltage drops.

    What speaker are you powering?

    RJ -

    Shouldn't be to hard for you.... Suggest you:

    On the power side let's make you use 4awg power and ground run directly to the battery / or distribution block. If going to a block, make sure you have zero gauge from the block back to the battery.

    On the audio side it sounds like you have a good match power/ speaker wise. Your going to want to parallel the speaker pods up at the top of the tower. (piggyback the ++ and the --). You will want a good 12awg speaker cable if powering 4 pods.

    Gain wise, make sure you don't bounce the mid bass cones off the grills. If so, reduce gain and or boost cossover point. Don't forget proper fusing for your amplifier.

    Any trouble hit us up here!

    Cheers,

    brian, so the + from one channel will go to the + on one speaker. then from the - on that that speaker it goes to the + and the next. then from that 2nd one the - goes to the - on the amp?

    Well that changes things a bit 100 watts rms is a perfect match then I assumed that was 200 watts rms and not 200 watts when lightening strikes

    Wire one speaker on one side to the amp, then wire the 2nd speaker on that side to the first speaker that's wired to the amp. + to + and - to -. Then repeat with the other pair on the other side of the tower.

    let me ask this, is the tower already wired, or will you need to fish it?
