2 ohm or not 2 ohm

if you run the amp at 4 ohms, then you will only be getting half the power that it is capable of producing.  i dont see any good reason to purchase an amp and only get half the power from it. (unless the speakers that you are connecting to it cant handle the power)

rockford is a good brand of amp, if they say its stable to 2 ohms, then i wouldnt worry about running it that way.

thats all well and good, but amplifiers are designed to give off heat.  should i ditch my 4 ohm speakers, and go with 8 ohms, just because my amp will run a bit cooler?  if an amp is designed to run at a given load, then run it that way.  if its a quality amp, and you have it installed properly, then you wont have any issues.

While I agree that this setup should have no problem runnign at 2 ohms that does not necessarily mean it must be done a 4 ohm load will cause the amp to run cooler and possibly extend the longevity of it, but it really depends on the power handling and the impedance of the woofer(s). I believe it's been used on this forum before but just because you have a car capable of going 200mph does not mean you must drive at 200mph everywhere you go. Just my 2 cents.

Do you drive your vehicle all the time at it's top speed?  If not, do you feel you were ripped off because you aren't using it at it's designed speed?

Just because an amplifier is stable down to a lower impedance doesn't mean you have to run it that low.  An amplifier is designed to run any impedance down to a certain point, not to run only at the lowest rated impedance.    Also, did you actually measure your speakers impedance to make sure their nominal impedance was 4 ohms?  After all if they were designed with say a 3.8 ohm DCR instead of 3.2 ohms then you aren't running the amplifier at an actual 4 ohms nominal load.

so because i have a different point of view, that means that i have a problem?     is debating not allowed in this forum? must we all agree?

my point is...why would you pay money for a sub amp, then run it at 4 ohms, when it is designed to give full power at 2 ohms?  seems like a waste of money to me.   if you guys like to use half of your amp's potential, great, go for it, its your money

since you guys like to talk about cars so much....would you purchase a car that could hold 8 people, and only fill it up with 4 people?  that would be a waste of money, now wouldnt it?

i am also interested in what subs he has....i dont see how he would have a choice between 2 or 4 ohms, if he has already purchased the subs.
