[QUOTE="MCM5595, post: 7208626, member: 630289"] Okay i just wanna know how wrong i am here... If I'm looking to get 2 12 inch subs that run at 300 RMS dual voice 2 ohms, i want to get a 2 channel amp that runs at 300 RMS at 2 Ohms.. so then each channel gets 300RMS and/or a 4 channel amp at 2 Ohms that runs 150 RMS each channel then bridge to channels to make 300RMS to each subwoofer (I'm disregarding 4 Ohms amps because i herd they were more expensive)...Or would bridgein the 4 channel 2 ohm amp up the resistance and make it a 4 ohms? now if i get 2 12s that run at 300RMS dual voice at 4 ohms... finding a amp that is 300 RMS at 4 Ohms is expensive ( or is it?) so i buy a amp that is either a 2 channel (being 300 RMS each channel) or 4 channel being (150 RMS each channel) AT 2 ohms so i bridge the 4 channels to simulate a 2 channel , i run the subs parellel so the amp thinks its a pair of 2 ohm subs but really it is two subs that are 4 ohms... honestly this is all information that i have observed from the internet and im trying to find out if i peaced it all togther please correct me where im wrong... wich probally is everything :P Thanks.
