I just bought a fender passport 150 and it isn't very loud and the channel lights aren't even coming on when I plug in my guitar or my mic. You can hear the guitar and mic but only when the volume is turned all the way up

Turn down the VIP knob and try it. This is on channel 1 for announcement voice overs overriding everything. It has a threshhold setting for adjusting that. Here is the manual for it.

Since you just bought this, exercise your warranty after verifying you have properly set this unit up.
