I will need ~400W per sub (02 channel).

Does XRK sell populated PCB?

Thank you.
He does sell completed boards (RTR) - ready to run. But, he needs a group buy of at least 20 amps to manufacture. Please see his thread here.

Keep in mind guys : this board is designed for the Automotive world. This means that you will buy it @ a fair price only if you intend to use it in a suitable environment.

I discussed with xrk971 a few weeks ago and he was very honest about it. The price of this card is clearly justified if your use is oriented towards the automotive world since the card is designed to resist vibrations and automotive stress conditions... consider this point carefully before your purchase

Even better, sounds like the card is built like a tank !

People who like or need to over engineer their amp will be thrilled.

Actually, it was designed not for automative but for professional audio - tour rigs and such. Lots of knocking about and bumps etc. But I did not want to sacrifice on sound quality or performance with regards to noise or distortion. It would indeed work fine in a car or any other high vibration environment (boom box), active speakers, motorcycles, boats, airplanes, boats, submarines, spacecraft, etc.

Secure Molex Minifit connectors are also used in all my other latest "home audio" amps (Alpha Nirvana and FH9HVX, and soon the Aurum-X) for the purposes of providing a quick and secure way to connect active power MOSFETs/BJTs to heatsinks, independent of the amp PCB. Lets you remove and service or swap out an amp board in minutes.

@orchardaudio The SMPS modules in this amp look very compact. Do you know who makes / sells them?
