These are great amps: 3.5mm and 3 pin header inputs;2.5/5.5mm and screw terminal power;treble,bass,and master volume controls+tone pot.
Come with stand offs and screws and 4 volume knobs.
Electros are 105C.Have mute and I think remote on/off.
I have spent the last 3 hours listening to it via X's excellent 0.53 Karlsonators+an 8" sub. Sound really good.Power supply is only 4.5A But have 350W to put in.
Going to crack another beer-am on holidays.

Great to hear feedback on this unit. Does one of the knobs actually allow you to change the low pass frequency of the sub? That has always been the main downfall of these 2.1 amps. This one looks nice though and they actually throwin physical knobs and standoffs? Unheard of for Aliexpress and at this price. I will buy if you say the XO frequency is adjustable.
Glad to hear you are having a good time with 0.53x K'nator. One of my favorite speakers. Which driver are you using with it? The single Dayton PA130-8 sounds awesome in it. About same SPL as dual Vifa's but has more mid range punch and can handle more power.
I've got the Breeze 2.1 with variable sub output. With a 19v laptop brick power supply the sound is WAY better than it has any right to be. Not rivaling my VanAlstine Fet Valve but hey it's so damn good for what it is and super portable to boot. The one thing I never could find info on is what is the crossover slope used for the sub output. Does anyone out there know?
4 PA130's should arrive today.
The ones I referred to have the vifas.
My son picked them as the best sounding speakers out of my six setups.
I'm building him a pair out of ply.
The 3rd from left knob seems to be a tone contol for the treble channel.
(if that makes sense).All the surface mount components are laid out behind the pots,but my old eyes can't read
them to figure out their function.
There is a lot of printed information on the back of the board;some in chinese,some in english,including 26 and 32db gain.

Don't know if I can post this link to ebay but I have the dual chip priced at $10.99 from electronics_lee
2 100W TPA3116 D2 Dual Channel Digital Audio Amplifier Board 12V 24V for Arduino | eBay
I have the YJ blue, Audiobah green, Sure 3116 and 3110 but the dual chip with no pop is my favorite. This best upgrade for these amps is a regulated PSU.
There you go.
Bass filter adjustable from 80 to 500Hz.

Looks like the Audiobah green board. One of my favourite 3116 board. Yup, no pop on turn on and off. Too bad I burnt both of them when tried to turn it into PBTL mode. Enjoy.
Regards,
Gee, this thing is cheap!! With 2 3116 chips! May be I should give it a try.
Regards,
So taken with the sound of the $10.99 dual chip and $22 Pyramid regulated that I bolted them together so they're one piece.
The connections would have been on the back but I had previously used this enclosure with a YJ blue/black board which had no volume pot and was turned in a different direction.
To my ears the 13.8V regulated PSU's sound better than the higher power units.

3116 and BT for $20?!
This is way cheap. A great deal if there is no BT ground loop noise.

No oscons on that board, just cheap electrolytics. Ripple current rating is 410mA, and the ESR (calculated from 0.16 dissipation factor at 120Hz) is 643mohm. They're awful!

Here's an actual OSCON for comparison. Only 120uF instead of 330, but 28mohm ESR and a 4.4 amp ripple current rating.
