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:

umm about 3" runs, from the board to a pententiometer and back, with the pententiometer about 1 inch away from the main pcb.I would be surprised if the board to the output terminals is even 6".
24g = 0.013Ω
18g = 0.003Ω
A difference of 1/100th of an ohm. Insignificant
(i used this calculator)
But i also use 24g solid for speaker wire … because i found it sounds better.

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.

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.
