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!

cheapo 8 channel L15D 4x 500va trafo noise floor on them is great plugged it into a 103db tweeter with no noise.

I was going to ask where the other 4 channels were until I saw that you had them stacked.. Well done!

Very impressive!

But, any thermal issues with the lower modules?

nope it was going to be 12 channels but i couldn't figure out what to do with them all so i only did 8 so there's about 4 inches between the top / bottom channels

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.
