If I have a 4 channel amp and use infinity 4 ohm speakers up front and infinity 2 ohm speakers in the rear will it matter to my amp? I dont want to damage my amp. thanks

yes
It will hurt the amp if its stable @ 2ohms.

Simple rule in electronics is this.
Anytime you put something in parrallel. The final resisitance is going to be less than the smallest reisistance!!
2ohm is parallel with 4ohms will lead LESS than 2ohms..
I use the product over sum rule:
2x4 DIVIDED by 2+4
8/6= 1.3OHMS!

I like Memphis too.

You should be carefull if the amp is 2 ohm stable!

Do you have a DMM?
Measure the impedence @ the speaker connection on the amp. Anything less than 2ohms is unstable.

2 4ohms in parrallel will yield 2ohms on the front speaker channels !!!!

2 2ohms in parralled will yield 1ohm on the rear speaker channels !!

You need to be very carefull. Why did u get 2ohms for the back?

If not runing them in parrallel. 2ohm load will be okay for the individual channel. You may be okay.
