- r - red = 3
- o - orange = 4
- y - yellow = 5
- g - green= 6
- b - blue = 7
- v - violet = 8
- g - green = 9
- w - white = 0

Likely a cross-over network and frequency dependent.
A simple design
Here's an intro to the subject of crossover networks
If R1 connected to C1 is burnt, then the POWER rating (of the resister) was too low for the inputs and you should suspect that C1 needs to be replaced too. R1-R2 is an L-PAD (ie variable with a knob) and used to adjust the cut off frequency.

Thanks for the info J.O.
I'm assuming its an L-Pad because it has a volume control and 2 burnt resistors of the same size. My dilemma is figuring the resistor size, (ohms, volts, etc.), without having he color bands as a guide. I'm a novice at electronics repair and was asked to look at it by my nephew. I included pictures of the board top & bottom. Black area on underside is were the resistors were positioned and top immediately left of the two capacitors. Is there a way I could calculate the resistor specs from the capacitors?

Yes - -depends upon the 'cutoff frequency' - - OMG, haven't done this in 30+ years so give me a frequency you want and and the numbers on the side of the capacitor and (gulp) I'll rummage about to find the equation . . .

Btw: those pictures are for an ACTIVE cross-over, not passive as I showed in post#3
Your best bet would to look for the part-number on the pc-board and the google for a replacement.

If you can't find a replacement, then get the nephew to build two of these as a total replacement for the active circuit
