Plan: SDX15 and a sealed 3.5 ft^5 enclosure.

My only question now, is the amp that powers it. I have two choices.

O-Audio
or
a Behringer EP1500

The only thing that would be stopping me from buying an EP1500 right now is that I have all my components in a cabinet, and the Behringer would be in there too. I could put it on top of all my other components or on its own shelf to give it the most airflow, but I do not know how how these amps get or how powerful the fans would be. I would be changing the standard out for the silent fan said in these forums.

Is the ~1000 watts that much better than the ~420 watts produced by the O-Audio?

Forgot that part...This is going to be a sealed enclosure, and this is mainly for music. Rap, rock, bass, everything.

The O-Audio has high pass filters and boost. The 12hz setting has 8 db of boost, 16 hz has 6 db , 20 hz has 4 db, and 25 hz has 0 db. Here is an SPL graph.

Green - EP1500 1000 watts
Yellow - O-Audio 420 watts HPF 16hz, 6 db of boost
Orange - O-Audio 420 watts HPF 20 hz, 4 db of boost.

With The O-Audio the Xmax is not exceeded. With the EP1500 Xmax is exceeded at 6 hz. (definitely not a problem in your application) The Ep1500 is a clear winner.

Ok, that makes the superiority of the EP1500 very obvious :bigsmile:

How hot does the EP1500 get? The longest I would have it on would be about an hour, but the thing is is it will be in a cabinet, but the door will be open on it.

I guess it wouldn't be terrible since the fan blows from back to front, so the hot air will be going away from it completely

And another question, there will probably be a few more as time goes on, but this one wasn't readily available on this site. I did research.

I am going to run speaker wire from the EP1500 about 20 ft. With 1000 watts going through this speaker wire, I'm not sure if I should go for a lower gauge. I currently have 12 at my house, and still have plenty of it where it came from.

12 gauge will be fine. About the heat, My EP1500 barely even gets warm, but I would not put any of my audio equipment in a sealed cabinet. If the cabinet your talking about is just an open shelf with no doors you should be fine.
