Default Which is Best performance wise - Bridging,Parallelling

Hello everyone, i am new to this community. I am a crazy fan of audio electronics. Mainly i've used 2050 till now. Actually i wish to know which technique is better for getting more power like:
1. normal bridging .
2. parallel connection of 2 chips
3. fedding inverted input to one IC and non-inverted input to second IC

1 and 3 are the same thing: that's bridging.

About performance, parallel and bridging attend different objectives: paralleling amps increase output current capacity for thirsty speakers, like 4 ohm types; bridging increases output wattage capacity, that is provides more power for 8 ohm speakers.

But the actual listened output may depend mostly on speaker efficiency. That is a low efficiency 4-ohm may sound louder than a high efficiency 8-ohm for the same power, when it should be the opposite.

Now you are mixing things together.

Bridge connection and parallel connection are two different things.

To the thread starter: You must first ask yourself how much power you want into which load.

Peranders: are you receiving cross-eyed mails?

Look again: I said 1 and 3 are the same thing, not 1 and 2.

Guys,

Have you ever tried this balance circuit? Will it work? I've build it but the output went to positive rail.

You missed pin 1, it must be connected to pin 5 (VCC), they are not connected internally.
You don't need R3 & R13, if you want you can replaced R3 with 10 ohm 2W resistor parallel with an inductor (single layer winding of gauge 18 enameled wire on the 2W resistor) and remove R13 completely.

With chipamps, for high power you may need to both bridge and parallel, to keep heat per chip in limits. See NS AN1192.

Bridging alone is arguably most commonly done to get maximum watts from a given (and limited) voltage, eg, a car's 12-14V.
