Bridged pairs for a nice bi-amp setup... and you have one of each chip to screw up.

You're going to need some power first...

Beautiful chips!But I'am using LM1875,TDA*** and so on.I decided to build a sub with a piece of LM3886 next month.

I don't think that I would advise anybody to start with a bridged amp!

Start at the source- go to the National Semiconductor web site and download a data sheet and any related ap-notes. The guys who designed the chips know a little about making them do their stuff, too.

The LM3886 is actually very easy to P2P. A pair of those and a PSU and you've got a fine amp. Just to start!

Wow!

I totally agree about the P2P. In fact, because you can actually see where everything is connected to, it's more educational than stuffing a PCB!
