  Looking for suggestions for a small 2.1 amp to power a set of passive Dinas. Ether off the shelf or DIY.

  Are you looking for a pre-made unit or to put something together, like a board or two from someone like PE or AliExpress?

  Either. DIY is fine. Only requirement is that it have a built in crossover for the subs on the Dinas. Thank you.

  Did you build the passive Dinas with the crossover in the build? If yes, you could drive the speakers with a 2 channel amp. I have a SMSL A12 on mine and its 80w per channel produce a lot of bass.

  @drdan No I did not include the cross over. I have a small 2.1 Chinese made amp that I can use with it but was looking to see if there might be other amps out there that would be better.

  @stevem This is where I really like the Arylic 2.1. You can actually determine the crossover and slopes via computer software. It is pretty awesome for that. Supposedly, it can handle 2ohms as well. I have never tested that though.

  @123toid This is a perfect solution for me. I have been wanting to get into DSP and this seems light enough for a beginner. How would you suggest attaching both subs (L+R) to this?

  Well you have two options. The first is (assuming the passive crossover version), just running these full-range and equing it. The second, you could use with either version of the Dinas and that would be biamping the Dinas. So take the L and power the top half of the left Dinas and the R to power the right half. Then parallel the subwoofers together and running them of the subwoofer out. Supposedly that amplifier will handle 2 ohm. If it doesn’t you can still run it this way, but you would need to wire the subwoofers in series.

  @123toid Just got the Arylic 2.1 in the mail after watching your review of it. Will let you know what I think after I get it hooked up.

  So I put it on an old shelf of aluminum and threw on some feet and fired it up. It sounds pretty good, i have to say. I like it so much I want to run a set of mini dinas with it. Did you ever come up with plans for a mini set of Dinas? Where the base would be a separate box? If you have please let me know.
