I'll start by saying that I know there are multiple threads regarding speakers for 80 series LC's, but I have yet to find info on my particular speaker setup. As far as I can see, I have two speakers in the lower dash (knee area), two in the rear doors, and one in the very back right/passenger side panel. I don't have stock speakers in the front doors. I would prefer not to alter anything and I'd also prefer to keep everything original looking, I just want to replace the stock speakers with something that sounds better, as I think that the stock (almost 33 year old speakers), are trashed. I haven't pulled the original speakers out yet, but it appears that the two in the rear doors have a 4.5" diameter grille, and the one in the rear has a 5" grille. Like I said, I haven't attempted to pull the speaker out yet, so I don't know the exact size of the speakers in the dash, but the grilles are rectangular and approx. 4.5"x4". So again, as far as I can tell, this is a 5 speaker sound system and I'm looking for recommendations to replace/upgrade all these speakers without any (or vary minimal), modifications. Any suggestions/recommendations?
