Do i need to replace my speaker's wire if one is louder than the other?

Here is the resistance in ohms per foot of different guages

10 .00118
12 .00187
14 .00297
16 .00473
18 .00751
20 .0119
22 .0190
24 .0302

Say you have 30ft of wire on each speaker.

at 24 gauge, you would have

1.812 Ohms of resistance (30ft x 0.302 x 2, since we have to calculate the complete round trip for the signal)

at 16 gauge you would have

0.2838 Ohms of resistance

Since you are probably running 8 Ohm speakers, the 24 gauge side has 18.4% more resistance than the 16 gauge side (9.812 in total vs 8.2838 in total). This will cause a pretty big difference in sound level.

The longer you run the cables and the bigger the difference in cable lenth for each side, the lower the gauge number you want.
