Do I need to have the same Ohm rating on all channels of a 5 channel amp?
I would like to run a subwoofer at 2 Ohms and most speakers are 4 Ohms. Would this be a problem all on the same 5 channel amp?
Thanks.

 

Youll be fine

 

Yep Even though the amp is 5 channel It's actually a 4 ch and a mono just all built into one. Most are class A/B on the 4 ch and class D on the mono.

 

What kind of 5 channel amp is it? I know I had a 5 channel class T alpine that wouldnt let you do that. I did it anyways and it clipped rather often and went into protection a few times.

 

I was told that the Memphis Belle is that way but after reading it on their website it says the belle "literally" combines the power of a d with the range of a class ab. So I don't know the "Literally" may have throw me off.

 

The amp is a Blaupunkt GTA 5350. The specs in the manual give RMS power numbers for 4 Ohm and for 2 Ohm for all channels. That's why I wondered if you could take those specs for 4 channels on 4 Ohms and the 5th channel on 2 Ohms.
This site gives the numbers for 4 Ohms as I see it listed in my paper manual but doesn't list the 2 Ohm settings:
