2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board
Can you invert phase one input to bridge output with both positives?
No, this amplifier is not bridgeable.

If I have the BT1A hard wired into the board, does anything control which input the amp uses? Do I need to put a switch in to shut off the Bluetooth when it's not in use so the inputs don't get confused?
what is J8 for? where can i connect a pot for gain control? thanks
I'm thinking of a project using this board and I may want to throw a 4 ohm speaker on one channel and an 8 ohm on the other. Is that a terrible idea, or will that work out?
There is nothing wrong with doing this on this amplifier.

Are the J1,J2 sockets for input (same as the 3.5mm jack on PCB)? If so, which is L/R? Same with Output, which channel is Ch 1/2 (L,R)? I'm planning on using sig input directly from a USB bluetooth receiver, powered by a step-down DC regulator (12v to 5v).
Yes, J1 and J2 are the inputs. J1 is Left and J2 is Right. J3 is Left output and J4 is Right output.

What is the idle current rating of this amp?
Sorry about that. Downloaded the user manual and it is 20ma with a 12VDC supply. Very good for battery operation.
