TDA7492 Digital Audio Amplifier Board 2x50W
Is the 12" wiring harness available elsewhere? I need one with the pcb clip. Thx
I got this along with a pair of "HiVi B3N" (8ohm) and a "50K Audio Taper Stereo Pot" but I couldn't get it to work. I used the pot in the output side and eventually made it go stinky. Do I use pot on input side? Which and how to wire?
a pot for volume control would be placed on the input side. Controlling volume on the speaker level side would require an l pad. You will want to use a 50k stereo pot with each input channel wired to one of the joined pots.

Could you use this as a subwoofer amplifier if you used a crossover before the amp on the line input? Would it work with 12v? Im using a lepai 2020+ to drive the mids and highs(stereo), and was hoping to use this to drive a mono sub. Thanks!
I had expected a simple diagram for in's and outs. For example, I have an 18 v dc power source, Love to know where to attach it. Phoenix connectors great .... 3....left speaker, right speaker. The chord...Input? Is there a pdf available ?
At the top of the page, to the right of "Product Details" there is the "Manuals & Resources". The first link is the wiring pdf you need.

What are the power supply specs if I'm driving 16ohm woofers? What is the limit on volts? The speakers are vintage, so rated 15 watts.
Recommended power supply: 10V - 26V • Requires 1A - 4AEstimated 25 watts at 16 ohm

Can this board (or any of these amp boards) be used for a guitar power amp? I'd use a tube preamp.
You could probably use this amplifier that way as long as the input signal from your tube preamp doesn't overload the input stage of the amplifier chip. It would be good to use a tube preamp that has adjustable output level to attenuate the signal as needed prior to the signal entering this amplifier board.
