I was wondering if stranded 18awg or solid copper 24awg wire would be better for audio signals, also how about for power supply?
I used the latter for audio signal, something thicker (and likely solid) for the DC/power supply.

24 AWG will have considerably higher resistance as it has a smaller cross-sectional area than 18 AWG.
Wikipedia has a table of the diameter for the varies gauges:

yes, short runs and small gage will work, longer runs need bigger cross sections for obvious reasons....keep losses to a minimum...
umm about 3" runs, from the board to a pententiometer and back, with the pententiometer about 1 inch away from the main pcb.
thanks for all the replies guys, i think i will go with the solid copper 24awg for the signal runs, since i ripped them out from ethernet cords, so they are pre twisted, thus i can easily double up the connection. i will go with the 18awg wires for the power, as signal loss isn't as important in it.
You are only worried about size from the amp to the speaker terminals. With signal levels i could happily use 30g (partly because i have part of a roll of silver coated copper with teflon insulation) or smaller.

Thermostat wire is sturdy solid 20ga copper.
When wire-wrapped around pins or hooked through vias, and then soldered, it doesn't come loose later. It is also available in 5 or 6 colors (inside the brown jacket), and the different colors are useful for organizing.

Need to be Careful about using Ethernet cable guts. Wire may be Copper coated Steel of the Solid variety. Nice and Strong for Plenum pulls.
Doorbell wire, (cousin of thermostat wire), is 2 conductor and available in 19ga, 20ga, 21ga. Inside the brown jacket, it is typically red and white. Also, nice solid copper.
You can take it out of the jacket and spiral twist it for quality.
There is a need to tie it down, since it might be stronger than the connections.
