Until you get the amp kit in a case with real binding posts, the little blue screw connectors will take up to a 14-16 ga. wire.
Amp board to preamp--you can use any IC you want.
I have had the 125x2 8ohm version of the class d audio amp up and running for a few months now and I am really pleased with it. It sounds great and was very easy to get up and running. As mentioned earlier Tom from class d audio is extremely helpful and will answer all your questions quickly. IMO this is an extremely nice amp for the$$. I have added a few links to the chassis,power inlet and wiring that I used.
So as a general rule, does that mean input wires should be narrow gauge (like ICs) and output wires heavier, like speaker wire?

Steve I powered up my amp and after about 15-20 sec it blows the fuse in the iec.Tom suggested i use a 6amp slow blow fuse, is that large enough? I have triple checked all wireing
I didn't fuse mine but I would think the fuse is big enough. Did you check your transformer taps? You have to get the correct blue and green together for the center tap. If you don't you'll cook the tranny. Believe me, I know from experience. Tom should tape the correct two leads together for the center tap but he didn't in my case and I guessed wrong.
Well that's the question. I told Tom to tape the correct 2 together before he ships them out. Don't know if he's doing this now or not. If they're not taped together, I would ask Tom.
If you look at the transformer there are 2 sets of green and blue wires the most outward green and the most outward blue are a pair. The green and blue that are right next to eachother coming out of the transformer are the other pair. Clear as mud?
Quote from Tom:There are 4 wires from the transformer. Two blue and two green, the blue and the green wires in the middle go to the CT. The outer green goes to the AC-L and the outer blue goes to the AC-N.
