well I'll partially retract my statement, I should have said MY TRUCK, lol, I replaced the speakers that were not stock speakers, sorry if I mislead anyone. The OBS trucks didn't have speakers in the rear doors, or at least mine didn't, they were behind the seat in the cab corners.
what I would do now in hindsight is go listen to speakers find you what you like, and then search on either ebay or the net, I found out sadly after the fact I grossly overpaid for my infinity speakers, had I bought off the net I'd have saved tons, but I"m on that can't wait, gotta have it now, and then get pissed that I paid to much, lol.
