I just saw OP is banned, so my efforts above were a bit futile...
Oh, well....
Can we have this thread declared closed by those in charge?

I was going to suggest an amazon 7850 built board that uses a correctly marked part. Also that it can be the best place to look for items like that.
Really, with 12 V single supply?
But I suppose you know more about the 3886 than any of us here!
12V is pushing a LM386 and a better choice would be LM380 or LM384. But just look for an amplifier made for the automotive market. Vendor web sites list them that way. Today, many are class-D and intended for low impedance loads which older linear chips do not handle so well. Probably avoid chips intended for high voltages because that usually means they have poor saturation voltage losses. You don't want to waste ~4V of your 12V.
LM386 is very low power.
Still available (often from a "second source") TDA2003 was designed for 12V operation and drives a 2 ohm load, to extract down to the last watt from such a low supply.
Tons of bridged output chipamps, both Class AB2 and Class D , designed for the massive Car amp market.
"Normal Voltage" chipamps such as LM3886, 1875, TDA7294, TPA3118 etc. ¨can be used at meager 12V but they become inefficient and performance suffers, better use those specially designed for that (as I mention above).

Brain fart on my end. I'm human. I'm sorry. 😉 The LM3886 will work down to ±10 V, so it would work on ±12 V. But not +12 V single supply. After all, the 20 V Vs minimum spec is there for a reason.
I did add the "technically" at the beginning of the sentence for a reason. The saturation voltage of the output stage in the LM3886 will eat up a lot of the supply voltage so it wouldn't be my first choice for a low-voltage amp. But that doesn't mean it can't function as one.
LM386 would work at the lower supply voltage but it is incredibly low-fi. That said, it was used in many PC speakers so it is capable of making a driver create some scratchy noises. 🙂

LM386 can not be called HiFi. Even PAM8406 is better (runs on 5V BTW). OP has left the building so posting is a loss of time and effort and those are usually entertaining threads 🙂

On 12V supply my current & all time favourite low power chipamp is TA8227P from Toshiba. This chip sounds fantastic despite its limitations. It's really good for near field listening levels.
After changing all electrolytics, now my spkrs performing like new!!

I wanted a simple amp for speaker testing so bought one built. I did look at digital but noticed that 8ohm loads may be a bad idea. Suggestions that different output filtering would be needed so bought a built 7850 amp as much quicker than diy. The one I have may find it's way into some self build PC speakers or perhaps diy. Those hopefully will b dml based - 😉 yet more work before I need to worry about amps. Can't help having an interest in class AB for this area.
