You can get all of the physical measurements of the part from the documents on the Mouser site (or at Alps themselves) to get the hole size for the panel(which I also needed to do..)
Thanks for the further info!

Very impressive!

But, any thermal issues with the lower modules?

Nicely done... I'm slowly planning on building a 5 channel amp just like your setup. I see all the components, and I also noticed the speaker protection circuit. Does the L15D require a speaker protection circuit? I thought the IRAMP7S (IRS2092) has speaker protection built in?

Did you add any line-in attenuation (can't see) or is it straight through from your pre-amp/receiver?

Yes. You need speaker protection circuit, because the mosfet failure cause dc error on output.
