On my '95 the speakers are in the doors, part of the interior redesign I believe.
These speakers fit the front stock location perfect as the are already 6.5" speakers, but only 6.25" in the rear for this interior.
I already had these kappas from the set up I had in my old '91 E350 and I love the sound, no need to run subs with these!
So I did this mod to make them work in my burb.
I'm running these with a JVC deck and all factory from there.
I haven't figured where to put in the 2(one for front, one for rear) 575watt 2 channel amps in yet, only because this truck is fully loaded so not much room with out loosing space.
