[QUOTE="mat3833, post: 7933282, member: 587645"] lol, im actually right. yes, the amp "sees" a ohm load. but = A+B since electricity will always choose the path of least resistance the sub with the lowest "ohm load" will receive more power than the higher load one. ill see if i can dig up an old website that had a calculator just for this type of thing. its more of a home theater thing. not really applicable in a car, but when you have 3 subs in 3 different types of enclosures all playing a specific frequency range it comes in handy if u dont have a single amp for each. for example if you have 2 D4 subs. wire one of them to 2 ohms and the other to 8 ohms. if ur amp pushes 500W in theory the 2 ohm sub will get ~400W while the 8 ohm sub will only get ~100W. granted ur final ohm load will be something like 1.6 ohms, but when u throw in series and parallel wireing configurations you can come close to a 1,2,or 4 ohm load.' since 8 ohms is 4 times the resistance of 2 ohms, the 8 ohm woofer will get ~4 times less power. its Ohms law at its finest. oh and ohms law is Current = Voltage/resistance.
