[QUOTE="d audio 450, post: 126532, member: 545894"] im sayin IF you had 3 loads im sure that the equation for resistance total (Rt) in a series circuit is R1+R2+ ect=Rt im in an EE tech course for school now- so i know it if you wire an 8ohm sub in series with a 4, the resistance will be 12ohms total, but the voltage drops will be different for each sub, meaning they wont have the same output power wire the 8 and 4 subs in parallel- (4x8)/(4+8)=(32)/(12)=2.66ohms the equation (4ohms)/(# of subs)=Rt only applies when the resistances are the same, all subs must be 4ohms i took an 8 ohm speaker, and a 4ohm sub, wired em in parallel and tested it with my good ol' radioshack multimeter- got 2.5-2.8 ohms, it kept jumpin back and forth between there i dont wanna sound like an ***, i just wanna make sure im tellin people the right stuff and all- feel fre to pm me or email me if ya want -pat [/QUOTE]
