    Is there anyone who can answer this?

    I was just wondering, does a lower ohm create more power?(in all cases)

    for the most part yes, lower ohms means lower resistance which means more power... but some amps like PG 600.1 it dosent matter cus it runs 600 watts at all ohms... check the specifics on the amp to find out

    if its regulated, then for the most part it will be XYZ RMS@1ohm or 2ohm and so on. something like a JL 1000/1 series are regulated.

    unregulated, usually means power will go up when you get down that impedance, although after a certain point its diseconomies of scale and you could well smoke your amp too

    Re: Is there anyone who can answer this?

    Even if the power is regulated...from my personal experience the lower ohm load still yields more power. It usually isn't a heck of a lot more on these types of amps, but it is still higher.

    I have also come across instances where an amp makes it's most power at 1 or two ohms, and dropping it below that only decreases it's power output.

    It's all amp dependant really.

    Re: Is there anyone who can answer this?

    technically, yes. on virtually all the amps you are going to come across, this is the rule of thumb.

    virtually ALL car amps are stable at 4ohms and higher.

    two channel amps (class A\B) and more (4 channel, 6 channel ect - just no hybrids) are stable at 2ohm and higher (NOT BRIDGED), but can ONLY be bridged at FOUR omhs or higher. if you bridge the amp at 2ohms or lower, you have good chances of blowing that amp up.

    mono - class D amps, are almost always 2ohm stable and higher - SOME (must list in specs) are 1 ohm stable, and even further, SOME are stable even lower than this. mostly competition amps and really oldschool amps that were built with very great components. mono amps (usually) only have ONE signal (rca) input. so they are only menat for subbass (whilst you CAN use them for music, its not recommended imo lol )

    there are exceptions, there are special amps, theres all kinds of crap, but unless you know otherwise, never bridge a 2 or 4 channel amp below four ohms, never run a 2 or 4 channel amp under 2 ohms regular, never run a class D amp under 2ohms (unless it specifies it can handle 1ohm) and you will be happy for the rest of your life.

    enjoy.

    Re: Is there anyone who can answer this?

    an amplifier is going to put out the same power no matter what impedence. what changes is the impedence of the load on the amp. if an amp puts out 1000watts, the impedence of the load is going to determin how much of that 1000watts the sub can use. lower impedence means more of that 1000 is getting to the sub
