Back in a 400 again
Those Suburban rear door speakers are for the optional 6 speaker system - the one that has an auxiliary amp under the seat. Other 4 speakers are the regular ones in the dash and far rear of the headliner by the cargo doors. I scored a set from the boneyard and used them to put rear door speakers in my old '94 Burb, with some very simple work, standard 6.5's will fit in place of the factory 5.5's. Nice find.
By the way if you've looked, that's about the only good way to mount rear door speakers in these 4 door trucks; if you try putting them directly in the door on the standard panel the only place you can cut into the door skin would position the speaker aiming right at the side of the seat's bottom cushion = sucko!
