Audio amp testing help

[winnston84]

I'm following wermys guide, and trying to test the audio. Can anyone guide me what I'm doing wrong? I'm aware my 3.5mm jack cable has one less wire than his - before I chop another wire up (this was from a 3 cable green yellow black wire for an old stereo) just wanted to check if my wiring up on the breadboard is wrong? Never used one before...!

Behind the black wire on this is a white wire

Hello,

I struggled for a bit with the amp testing. then I figured that I wasn't using ground.



The 2 soldered wires are L and R and the bare wire is ground.

I hope this helps.

Your positive and negative are swapped. Look at your breadboard power supply. The + is on the blue and the - is on red.
