Is anyone still interested in this? If there is sufficient interest, I'll organize the PCB purchase ...

Would it be able to run at 2 ohms ? If it could run at 2 ohms, I could run one to each voice coil on my Adire Audio Brahma 12 .

Interesting project. Somebody knows the approximative price for all the requested components?

schamatic/layout files

Does anyone have the layout files that are used for this PCB. I would prefer the source files, and not Gerber files as I would like to add some features to the board.

I have access to a large number of PCB design tools to convert the files to.

When I am done updating the design, I will gladly upload the design for the fellow DIYers to use.

Thanks,
Aaron Low

I'm interested too.. I'll confirm when the estimated price is known.

These chips are now on lifetime buy so if interested I would get what you want from National while you can.

The LM4651/52 set can run 2 ohms but current limit will kick in. Better to run no lower than 2.7 ohms. (8ohm // 4ohms).

im also interested with the group buy

How would you run this chipset at 2 ohms as o/p filter is meant to be load matchin int it.

Interested... but I'm confused. Is this for a 2.1 channel amp or for a sub amp?

If it's just a sub amp I'd be down for two.
