Audio amp help needed please

[Brownie]

Hi everyone, I need a little help.

I have this amp

Where do i wire up the power and audio? Do I wire the speakers to the back of the board using the + and -. Also on the speakers I have theres a red pen mark on one side of the connectors. Which side is ground and which is power? Is ground the connector thats marked.

Heres the amp - http://www.dx.com/p/pam8403-dual-ch...-control-black-green-blue-214329#.VcjnsniprFI

Help much appreciated.

Vcc and Gnd are your power connections, VCC is + and GND is - (Ground).

INL and INR are your left and right signal inputs respectively. And you wire your speakers up to the R+ R- and L+ L- pairs. The polarity on the speakers doesn't really matter 99% of the time. You'd have to have a really strange speaker for that to make a difference.

Thank you very much.
I'll try and wire everything up and see what happens

You have yourself great amp there. It's the one I'm using in all my projects now. It's cheap, loud and clear. It also runs on 3.3v perfectly.

I'm glad the PAM is catching on, there hasn't really been a standard amp around here but this thing is usually only $5 a piece.

Just out of curiosity, does it come with those connectors that would be used on the top left?

The connections you would make with those pins are for pin headers https://www.adafruit.com/products/598

However, all you need to do is solder wire to the pins. That looks like it's for premade female header connections on your other components. You can put female headers on your wire so that your connection can be removed without soldering, but I don't see why you would want to especially with so few connections.

Yeah that is what I figured that could be do. I just thought maybe they were nice and would send over some female connectors to go with it lol.
