Modifying an old amplifier/speaker for a separate input using wire clips instead of a stereo jack.

Step 1: Disassembly

Here we have the base audio amp and speakers from the bottom of an old Dell CRT. We're going to add an additional input to this so that we can push through sound from our MCU projects and other things that a stereo jack is too cumbersome for.
You have to remove the two back feet to access the last two screws and get the cover off.
Why not add alligator clips to an audio plug? It would be portable, just as easy, removable, and wouldn't void your warranty.
nice idea... I'd put stereo rca jacks on instead, but that's just me :-)
I might have as well, but for temporary connections, and also due to the fact that I always have problems with audio cable strain reliefs, I thought this would work better. However, I might still add a revision with optional RCA jacks as well. Thanks for the suggestion!
