hay guys, i need some help on the tchay audio amp i have wired up:

i have hooked up the tchay audio amp to my gc, and i tested it out.

27/12/12

i stripped the wires of the +4.5v/GND and L/R/GND for hooking them up to my gc's GND/+5V/L/R

hooked up the tchay audio amp to gc:

the headphone jack works fine, gives very loud sound, when i lower it, a buzzing sound is heard, but it's really loud,

also the sound from the speaker is low, even when i put it to max volume, you can hear the song a bit, but not as loud as the headphones,

why is this?

also, does hooking up both L/R cause this? since the amp is mono, but it can use stereo too? how?
also i have connected the GND of the power and the gnd of the L/R to the gnd of the gc, is that okay?

any fix?
