True or he could be smart and cost effective and wire down to 1 ohm...

1ohm stable amps are not always more cost effective (cheaper) than 4ohm stable amps. And some people swear by running A/B's, even for subs, in which case a final load of 4ohms would be preferable. But yes, I get what you are saying, there are a lot of cheap(ish) class D amps on the market that produce their full potential @ 1ohm.

This is true its just generally speaking 2000 at 4 is gunna cost quite a bit more then 2000 at 1...

True. But Im under the impression he already has an amp. I may be wrong with that though.

Ya I think he might...

Trying to keep The ohms higher on my amps to put less strain on my electrical for the setup I currently have.

I know people will argue this but IMO 2000 watts is 2000 watts and itll pull pretty much the same on your electrical no matter the ohm load its at...

There is a difference in efficencey, but if its a strain at 1ohm it is going to be a strain at 4ohm

Ya I know there is but how much is it really gunna matter...

Impedance is not directly related to efficiency. There are plenty of class D amps that are more efficient running at their optimal 1ohm load than their counterpart class A/B amps running at their optimal 4ohm load. This whole topic that has become popular lately, about efficiency and even S/N at various impedances (usually implying you will automatically get better performance at higher impedances) completely ignores amplifier design and topology. That's a pretty crucial thing to ignore when making a blanket statement.
