Where is my amp ???

[cougar190]

I have a 1994 F150 that has the Premium sound system . My left side speakers have quit working both front and rear . I've checked out the speakers themselves and they are fine , tried a different stereo with the same results , no left side , so the only thing I can figure is the factory amp has gone bad !! So what I'm asking is , does anybody know the location of the factory amp on this system . I'd like to simply bypass it if possible . any help would be appreciated !!! ...cougar...

If you remove radio . Look at plugs in back . The amp has a piggy back harness that plugs into stock radio harness and should be laying/attached in area behind radio. Unplug there and plug in radio and should be good to go.
