Amps

[bugman]

anyone know anything about amps, i can get sound out either the left or right but not both at the same time, (sound out of left if switch wire around, and right if i switch wires again) checked all wires and all are strong correct conections. i'm thinking its the amp, i did notice the other day it was getting pretty hot (which they arent supposed to) and its three years old.... speakers are both working, just not at the same time.. ::)
