I 've purchased the 50W version and I 've installed it into a tractor which had a broken, worn-out 1 DIN slot and it works good. To connect it to the speakers, I 've bought a set of female ISO connectors. It 's switched by the ignition key and from the potentiometer, if you want to turn it off.

can you use the aux input and bluetooth interchangeably or do you need to unplug the aux input cable before using bluetooth?

Hi! I have TPA3116 on similar board and with just the same potentiometer knobs, just with additional tone controls (Bass and Treble). I bought some small plastic enclosure for that amplifier but those pot-knobs are somehow too tight so I am affraid I will break something if I use excessive force to remove those.. Am I doing some mistake? I used to remove similar caps, but I never had such problem. Is there any trick to take off those caps?

my power supply will be a 10.8-12.6V (3s) battery my bms can provide up to 10A is that enough for 30W+30W? my speakers are 14Ω and they draw less power naturaly, Im afraid I wont be able to get 30+30 with the 10.8V my battery pack has 6 batteries and I can change the BMS-configuration to get 22V if its realy needed

Hei how many Amps this support I have an old hp 65W adaptor 18.5V 3.5A, can this burn the circuit, or I would be safer with 9V 1A as I only want to use it on 15W 4ohm RMS speaker

the 2x 100W version actually supports down to 2 Ohm per channel, the 2x 50W does not you will severely underpower the speakers though (which isn't bad but wont get anywhere near as loud as it could)

Well first of all, if you want more volume you need a power supply that outputs 24v dc (at max) because these TPA3116 provide little power when powered by 12v power supply. Second, you need to check if the circuit have a NE5532 as a pre-amp in the input stage of the aux input (analog input) this helps when using low volume sources, as a smartphone headphone output.

I wish you would have said a bit more about your line source when testing the AUX. Granted, this is a product intended to be built into a passive speaker to turn into an active one, and I guess one would mostly want to use BlueTooth, but I think once you've got the amp hardware, it's kinda stupid not to also equip it with a dirt-cheap analog connection that could come in handy some day. Maybe you could measure the signal when testing the line-in... line level is supposed to be up to 5V, and if they tuned it to allow max gain at that input level without clipping, some sources may simply be impossible to get decent volume from (like if their output level is only 1V). Maybe try the headphone output from a cell phone (if you've still got a headphone jack!) and make sure the volume on the phone is cranked up to the max...

You need 24V 5A+ to fully power your speaker properly. Read the discription.

It's all good as long as the supply voltage isn't to high for the amp and the power supplys max power rating is greater than the combined speakers max power rating, so you don't overload the power supply and burn it out.

One word of caution though: The bluetooth connection on this amp is open for any device, this means anyone who is near you can connect to it, even while you are listening. What is most infuriating is, that the new device will always be prioritized when it first connects, so you will be kicked off your own amp, which will drive you crazy!

Used an old leather belt to mount to the box as a carry strap. Quite frankly, it sounds like God! I built this for my wife, who wanted a portable bluetooth speaker that she could carry around with her anywhere, and plug into a 110V receptacle. She craved something that sounded better than the junk bluetooth speakers they sell in stores, which we bought several of, that were all pathetic. They lack bass, true stereo sound, and an appreciable loudness. With this speaker, the bass is decent, and tight, the flawless sound quality is nothing short of excellent, and the volume levels are enough to fill a large room, or even an outdoor party in the 1 acre backyard. Total investment: (Not including the speakers I had laying around the garage, and the particle board, glue and screws I had in my workshop.) - About $16.00 USD A little over $8.00 for the amplifier, and a little less than $8.00 for the DC power supply adapter. All purchased on Aliexpress.

The 2.0 did not sound great, and was overall just worst. The 2.1 is great for a pair off speaker under 200 dollar. The watt rating is obvious fake, are probaly alot lower. For me when is switch between powersupplys with different wattage the overall loudness didnt change. A power supply with 20-50 watt will be great, and a 18-24V Are also great. I use a Harmon kardon dc power supply that is rated 19V, and 2A (38W) and the 2.1 version was able to run the most unefficent speakers to such high volums that it damage my ears. So it plays really loud! Great buy for a lower to entry level setup, no noise and high watt output.
