    Running a 4 channel amp at 2 ohm vs 4ohm

    Say I have 8 speakers and I wire 2 In series togther per channel and comes out to a 2ohm load per channel would it sound as good as if I had 2 smaller 4 channels and ran 4 speakers per amp at 4ohm?

    Also if the amp is 2ohm stable does that mean I have to run 2ohm load to each channel or 1ohm load to each channel

    2 ohm stable means what it says in the owner's manual. If it's 2 ohms stable in stereo that means you have to keep it at 2 ohms or greater per channel.

    As to which would sound better, 8 speakers on one amp or 8 speakers on 2 amps, I think it would just be loud either way. You technically should get a bit better sound quality out of the 2 amp setup due to less THD, but it's still a lot of speakers. More speakers is not always better for sound quality. It seems you're more concerned about getting loud.

    Is there a certain combination of speakers and amplifiers you're looking to use?

    yes I plan on running 8 crescendo 10inch mid drivers on a big 4 channel such as a sundown 200.4 or a 175.4 dc

    Then screw the dual amps and run them off one good 4 channel. That will get loud.

    a lot of A/B amps will get VERY hot and even thermal protect running at 2ohm per channel. Just an FYI as I've seen it numerous times...

    I'd do 2 4ch amps and run them bridged at 4ohm per channel. That's how I run my PA stuff.
