So, I got these kits for Christmas and I immediately started to build them. I finished all three of them on Christmas day. The picture on the left shows what the boars look like when all the parts are on. I didn't attach the driver transistors because I had was using the heatsinks to figure out how to build the case. I wanted something compact and cool looking that I could make with parts that I already had. The best solution seemed to be to use the heatsinks as part of the case. This would make for a really small and cool looking case.
To the right is a picture of the half assembled case. I got the most of the parts that you see from Radio Shack, except for the switches. The heatsinks are just as long as the PCBs so the fit is perfect. I put the Stereo amps on the bottom, side by side and the woofer amp I stood straight up on the right side with the cutoff adjust knob sticking out the back right corner. I could see right away that there was going to be lots of wires. I won't go into detail on how to wire the whole thing up because it's fairly simple and you can probably figure it out for yourself without much difficulty. Anyways, with as many wires as are in the thing, it would take forever anyways.
One thing that My Dad keeps reminding me to do (with good reason) is to test everything before you put it together. When I hooked up the sub amp, it didn't seem to work. Dad and I got out the voltmeter and started poking all over but everything seemed to work right. Then, Dad was playing with the current knobs on the power supply and it started working. It turns out that we didn't let the amp get enough current to run right, but when it got more, it took off and worked perfectly. The other two Amp Circuits worked the first time too.
I went to Lowe's and got some screws to hold the PCBs and the front panel on. I also found some screw in the basement that went into the little channels in the heatsinks perfectly (visible in the picture.) It was really hard to get the whole thing together. I had to reach inside with my big hands and hold the nuts while I tightened the screws. I put the left heatsink in last because that was the only good spot to reach in.
(When I find a picture of the finished product, I'll post it.)
