I tried the search engine and i don't get the wanted info. I am looking for a DIY board kit, of class AB to drive a passive sub i DIY'd. I would take care of the power supply myself and buy a chassis and sink if needed.
An amp that includes the usual, low pass filter and level adjust features.
It's going to drive a 4 ohms 10inch sub-woofah.
Has to mix stereo channels into a single output.
Thanks!

Oh and i forgot to mention that it needs a speaker level input so, basically like a subwoofer plate amp but external, driving a passive sub. Not a lot of replys yet 🙁
Are you having an xover already? What about it?
I went through this decision making.. I am not very experienced and in the end opted for a used PA amp, and added an Alto X23SW active xover which I will want to (try to) modify (a bit of improving its psu, and if possible adding gain and modding it from 12 to 24dB/oct).
I reckon so far I saved some money in my pocked and mostly saved a lot of time and efforts in case there would have been diy amp production problems.
I am missing though a continuous phase adjustment and noise of the amp fan is not bearable for late night listenings (keeping sub(s) off).

That is exactly what i would like to replicate. This SA230 is Back Ordered, too much sales i guess?!. Plate amps are almost ALL junk. Unreliable cause of continous vibrations and overheating...
What kind of power do you need?
I'm sure the Neurochrome is about the ideal you can build but not sure if it would meet your power requirement.
@tomchr can help you though

I need from 60 to 120 watts BUT with the low pass, stereo to mono, adjustable x-over frequency, and gain control...
I did build one 15 years ago and was a pain and not worth the effort. Used a SC sub controller circuit (see below) with a ESP Project 101 amp.
Recently I've built sub filter based on ESP Project 81 with a fixed crossover with gain and phase normal/reverse which feeds a Project 19 (LM3886). Rod may have a sub project that suits.
12dB / Octave Linkwitz Riley Crossover
Ebay has some kits for sub controllers but the one I tried was not great.
I found it better and less hassle just to buy a plate amp.
