Unless you're going to add lid speakers, that amp is overkill for 2 speakers.

 

Yes sir. What ever you do, DON"T bridge that amp tp 2 6.5 speakers.

 

Yeah for sure, if I get that amp it will be with 6x9's in the lids also.

 

OP in your Rushmore fairing you would probably have enough room for a DSP and two small amps. With that setup you could go with a 400.4 bridged for the fairing speakers (a little fat on watts maybe but you could tone it down with your DSP) and maybe an SD 800.4 bridged for the 6x9s in the lids (that's what I am using now with my Hertz Neos).

In both cases that is more than enough power but with a DSP you can drop the mids and highs to where they sound warm and drop the gains a tiny bit to keep from overpowering things. Even in the southern summer heat my 800.4 doesn't get too hot pushing the 6x9s in the lids.

I agree with the others here that my SD amp is awfully bright, but the DSP takes care of that just fine. I have been well pleased with how it performs though, I'm glad I went that route on the back end. Just some food for thought.
