Removing interior trim panels to access factory amp on 1995 B230

[Woogie]

I have a 1995 B2300 SE extended cab that came with the "premium sound" and the factory amp has gone bad. I assume the interior is identical to the Ranger. I'm going to be tackling it myself and I know the usual install location is below the passenger side rear window above the jump seat. I plan on running the wires from the stereo to the speaker wires connected to the amp. Can anyone point me to a video or guide on how to get to it?
