technicly John is right, but thats not how they really do it. if your amp is 500w @ 4 ohm and 750 @ 2 ohm, you hook a 4 up to it, your gonna get 500. Even tho "internally" the amp is seeing 2 ohm. thats is why most amps have a problem running 2 ohms ( pair of 4 ohms ). altho they are getting better at making the amps play at 2 with out problems.
im running 80 watts to it, and it does just fine for out put. not gonna make ears bleed, but enough to get a ticket i spoze lol.
you have to also remember are they running stereo or mono, it makes a huge difference.
4 ohm mono is not the same as 4 ohm stereo.
internally the amp seeis what the final load is, and that is determined by the subs ohms.
also to let you know a 4 ohm sub is not always 4 ohms, most likely it is DMM'd at about 3.4-3.7 and also when a sub moves from one excursion to the other excursion the impedence lowers so a 4 ohm sub in peak excursion will make the amp see about a 1.5ohm load, that is the real reason alot of amps have a hard time with 2 ohms, because during peak excursion it is oerating at less then 1 ohms.
i have actually run 1/8 ohms load on MMATTS amps
and for the love of god do not thing a capacitor will stop your lights from dimming, if your lights are dimming you have other electrical issues going on. Anyone who knows how a capaictor works will tell you that in car audio a capitor is best suited to filter out AC ripple form getting into the amps power supply.
