Ive got an Alpine MRP-F300 4 channel amp (50w x 4 at 4 ohms, 75w x 4 at 2 ohms) and i want to power 2 alpine type S 6.5's which are 4 ohms each and 2 infinity kappa 6x9's which are 2 ohms each off of that amp.

If i wire up the speakers normally (each speaker gets its own channel) then how will the power be distributed amongst the speakers? Will the two alpines get 50 watts each and the kappas get 75 watts each? Or will the amplifier sum up all of the speakers ohms and create a load that the amp can not handle?

What about bridging two speakers and leaving the other two on their own channel? Or any combination that is possible with the amp and speakers ive got?
 
The two alpines will get 50 watts each and the kappas will get 75 watts each.

Bridging will be at no advantage.
 
well it all depends on how much power your trying to get to the speaker the lower the ohm the more power , but i heard that speakers sound better with low ohms because the amp is not running as hot
 
Ok, a 4-channel amp with 2 speakers that are 4-ohm and 2 that are 2-ohm is ok, if it is 2-ohm stable, which yours is. Like Sparky said, the 2 4-ohm ones will get 50 watts, and the 2 2-ohm ones will get 75 watts. The amp will not blow up, and an amp will run hotter with a lower impedence.
