[QUOTE="Astyl, post: 2272935, member: 566433"] Alright so to get right to the point, Amplifier RMS Rated Power and Ohm Rating Means next to nothing correct? It is what you set the gains at that makes all the difference in the world. For Example here, lets say you have a 500 watt rms subwoofer.. and a 3000 watt RMS amplifier, and the amplifier says it does 3000 watts rms @ 1 ohm.. Well that is NOT true.. just because you have your amp set on a 1 ohm load does NOT mean that it is going to play 3000 watts RMS, it is all in the gains! If you set your gains with a DMM, and match the output voltage on the amp to correspond with the RMS power of the Sub, aka 500 watt Sub working completely fine with a 3000 watt RMS amp.. what does it matter what ohm load or capability this amp has? Its all in the gains.. You can set your gains to whatever power you want, just because of the ohm rating, it dosent mean thats the power that its going to do, its how you set it up, correct? 3000 Watt RMS Amp rated at 3K Watts @ 1 Ohm 500 Watt RMS Subwoofer These two can go completely perfect together, even if the amp is played @ 1 ohm, because you have turned the gains down to output 500 watts, not 3000 correct? so what does it matter?
