    Alpine type r dual 4 ohm vs Alpine type r dual 2 ohm

    ok i am wondering, i am not the brightest crayola in the box with ohms and everything ... but i was jus wondering what is the difference ... i mean i go to look at amps and it shows taht at 2 ohms they can run at higher watts .. so whats that mean ... i am just unsure which to go with ... I mean if i go with a 4 ohm other than a 2 ohm what difference does it make? thanks a lot

    same speaker with different impedances so you can wire for the most power of your amp or to get to a certain impedance.

    Re: Alpine type r dual 4 ohm vs Alpine type r dual 2 ohm

    wait so it says 4 ohms ... runs at 500 watts x 1 chan ... doenst that mean that it would only give each sub 250 watts ... but if i only have one and run it on the 2 ohm wouldnt it push 1000 watts rms to one sub ... man this is kinda confusing

    that may help ya. you want to match the subs impedance"ohms" to get the desired output out of your amp. If ya are running one sub... get a dual 2 because it can be hooked up at one ohm. If you are running two then get a dual 4 because they can be wired together to create a one ohm load.

    Re: Alpine type r dual 4 ohm vs Alpine type r dual 2 ohm

    get the dual 2 version.

    this way you can run it as 1 ohm or 4 ohms. i say run it at 1 ohm and watch the gains.

    IMO in single dual 4's you have lack of flexibility.

    Re: Alpine type r dual 4 ohm vs Alpine type r dual 2 ohm



    so if i did something like that would i be over powering my subs? because if the dual 2 is hooked up to be like a 1 ohm then it would be running at 1500 watts rms ... shouldnt i do something more like



    then if i do that ... it would be ran at a perfect 500 watts rms ? i just dont want to over power my sub but at the same time get what i want out of it

    for number 1, just watch your gains. set it using the tutorial stickied on this forum. its okay to have a 5kw amp running a 1kw sub, just be extremely careful how you set your gains.

    erm for number 2, hifonics really isnt notorius for putting out its rated power, so yu will be underpowering that sub at 4 ohms
