Class D Amp Kit or/and Car Amp?
 
I have a few questions about class-D amps:

Does anyone know of a complete Class-D amp kit for 3 to 5 channel in one chassis (100 watts +)? A kit that contains everything and all you would have to do is just solder and put the kit together?

Most cars power amps are Class-D, is it possible to reconfigure those for home audio use? Has anybody tried a car amp in a home system and what were the results?

Yes, the 41Hz Amp9
"4 channel amps for 12V - 24V and low impedance loads

* Four channels of Tripath sound quality, based on Tripath TAA4100A
* Output 4x50W at low distortion, 4x100W peak
* Suitable for low impedance loads, 4 x 2 ohms 12V typical
* Up to 27V supplies make them suitable for 12 or 24V systems.
* Outputs can be paralelled for even higher outputs into very low impedance loads
* Mostly hole mounted components. Relatively low component count."
From the 41Hz site

It can be a bit fiddly but you get good back up from the the forum.

A lot of home stereo/theater are class D ICs, some you can look in the back and see them. I was thinking of building one of the larger 100rms IC like an STK but not seeing much here and some of the data sheet is in Japanese. The issue with cars is you need a switching power supply and they are more of a pain to build, with home amps you don't, but otherwise the amp itself is the same thing. If you find one the right size you can cut the PS out of a car amp. Of course if you don't have a board for your IC then the project could be much larger depending on your skills.

I actually have the amp9 built by vbro off of the 41hz site but I have actually never used it. I am still debating if I will put it into action or sell it off. My assumption is with the low profile version which is a 12volt amplifier I will need to use pretty low impedance speakers to suck some power out of this amp. I have built a few amp 6s myself and they sound pretty good, they may end up in my car.

excused but I do not know l' English and this are a translation online with babel fish

for an amplifier in class D to use in car you can watch the products of cold amp, have planned a good adaptable converter DC-DC to various requirements.
