Default PCB for LM4651/LM4652

I need a PCB for the LM4651/52 chips that is single sided sided and easy to hand etch.

size doesn't matter.

Also, can this chip be bridged? I am working on a car amp, and want to achieve the highest power with the lowest heat possible

I suspect that these chips more or less need at least doublesided pcb's due to the RF emmisions = hard to listening to the radio.

I smell there is one coming up but unfortunately not too soon.

I wonder that a digital amplifier hasn´t become "topic" of a group-buy already with all those fanatics around.
Now that´d be an interesting project and a bargain probably as well looking at the prices of these amp-kits.

I got the chips for a prototype, but then was put off by the distortion performance. Of course, I now know that those figures are fairly typical of the breed, but I now have other more pressing projects to work on...
