    2 ohms on 4 ohm amp..

    ok im assuming this probaly has alot to do with the amp itself, and i know running below rated impedance will cause over heating problems, and be abusive to the amp in general..

    but do you think it would be possible to run an amp under its rated impedance without major issues (say run 2 ohms on a 4ohm rated amp) but try not pushing it to full tilt... say its rated at 300 @ 4 then run it at like 250 @ 2...?

    Is it rated for 2ohms?

    Re: 2 ohms on 4 ohm amp..

    Depends solely on the amp, and how well it was built.



    ~/~Setup~/~
    *Alpine CDM-9803 Head Unit <-- New Alpine HU, forgot model #.
    *Front Coaxials - Pioneer 6.5" 3-ways. No rears.
    *Speaker Amp - Hifonics TXI4408.
    *Infinity Perfect 10.1 Subwoofer.
    *IB Mounted to dear deck, sealed from cabin.
    *6 Gauge wiring, to amp. All 14 gauge wiring for speakers and 12 gauge to sub. Cheap Home Depot RCA's.

    HU - $80. Sub - $50. Coaxial's - $20. Wiring - $20. Amplifier - $90.

    For under $300, a complete system that sounds rather good for what it is.

    Re: 2 ohms on 4 ohm amp..

    wouldnt this send the amp into clipping?? why not just upgrade amp if you want to go lower?

    No, it wouldn't, if it could handle the load without frying. If it can't handle it, you'll be able to tell by either it going into protection mode, or getting extremely hot.

    It'll be less efficient overall at a lower ohm load though.

    All depends on amp, is it rated?

    depends on the amp, some will smoke, some will shut off, some may take it ok with impedace rise, some may flat out do it with no problems

    Re: 2 ohms on 4 ohm amp..

    depends on the current draw. i run my 500x's bridged @ 2ohms (4 ohm stable bridged) on my doors with no problems




    too slow

    Re: 2 ohms on 4 ohm amp..

    i honestly would recommend to run any amp below its rated impedance, it might work but stress the amp

    Re: 2 ohms on 4 ohm amp..

    You will be fine so long as you arn't trying to constantly exceed the current capacity of the amp...



    figure the amount of current the amp should be able to provide at it's rated nominal impedance, and set gains accordingly to the new load so you arn't exceeding that amount by a lot..
