FBHDZVV Audio Amplifier TPA3116D2 Dual Channel Digital Power Board XH-M543, DC12-26V 2x120W DIY Module High Power Stereo Amp Board for Car Vehicle Computer Speaker DIY Home Theater Audio System

Q: Ti spec said tpa3116d2 is 2x50w or 1x100w. with two tpa chip it can be 2x100w. how does this board get 2x120w?

I believe this is an erroneous calculation based on the fact that it can drive 2 x 30W at 8 ohms, following ohms law once could calculate 2 x 60W at 4 ohms, however, to obtain 2 x 30W at 8 ohms, a duel layer pcb is required which this may have, I wouldn't know and don't have it on me, but still the claim is not supported by datasheet. Or maybe they calculated it by the figures 100W @ 2 ohm 24V and voltage max being 26V, but that doesn't calculate and is also not backed up by data sheet. Nice amp though.

Q: What is the name/type of the 3-pin connector used for the inputs? I need to find one with leads, not a connector.

Recommend a Kinter MA170 12V 2 Channel Mini Digital Audio Power Amplifier from Amazon. Much more civilized.

Q: I want to replace the 2 potentiometers into one. What resistor rating should it be?

Honestly, there is a different board with the Volume and a lid/bottom combo for near the same moeny. Should you really want to employ a different pot setup for an existing board, it would be like a 0-10k ohm. Looking at any ole RCA connected volume controller/Bass knob for a car amp would be a premade solution. search for the BLC-3 8$ knob , maybe you can get an idea with it.
