Nobsound TPA3116 Mini Amp Gain Fix (aka Breeze Audio) 

Interesting. The bridge mode would be my next question actually. I'll keep looking as my demand is not something to be left still in the desktop. Maybe I'll have better luck looking straight for a car amplifier that bridge mode works out of the box. Appreciate your inputs though.

Тhink about it inductors "conduct" dI\dt i.e. change in current. They don't have much of resistance. They wouldn't get that hot since they are not ''conducting" the entire time like a DC device

I've also been trying to find info for a mod on the dual chip version. I did run across a forum entry on a topic that had a 1000 pages or something that mentioned it but it was a small quote from another post and I couldn't find the original. I agree the gain on that dual chip is just too much. with a 12 volt battery about 1/3 volume is approaching (if not already) overkill. I'm using polk t-15 speakers . With my 24 volt 4 amp power supply somewhere around 1/4 volume is pretty much the maximum and it is way too much. I did just run across something about swapping out the op amp chip in the dual chip amplifier but haven't researched that enough to figure out what the story is with that. Mainly wanted to let you know you're not the only one looking to mod the dual chip amp to reduce gain.

@@jsdspif3 did either of you figure this out?

the size and power consumption. i have vintage receivers and frequently check goodwill for things like you mentioned, but this type of amp absolutely has a place in my life, even among other more "audiophile" leaning components. i have the dual chip version, which should put out around 25-30 watts RMS per channel into an 8ohm load with a 24v power adapter. that is enough real power to drive the vast majority of speakers to good decibel levels without clipping. these amps are great for a portable audio system, or for just being portable on their own, you can bring real power with you anywhere you go. i find it ideal for a desktop computer audio setup. i use it to drive a pair of modded minimus 7 speakers (mcm woofers, custom crossovers) and it beats the pants off most "computer-specific" speaker systems that cost 100s of dollars. this also has obvious uses in car audio systems, especially if this performance can be achieved with ~14v of power over time as the technology advances. we could have headunits capable of delivering real power without the need for external amps. these will only get better and more powerful over time.

Uh... You know this is a switching amplifier, right?
