imagine this visual.. door panel is off, stock speaker is out, you put the speaker into the hole into the door frame and mark the holes to drill.. drill with 1 size under the mounting screw that were supplied with the speakers you purchased screw the speaker in.. thats as easy as i can put it. i can't tell you sizes as i haven't a clue what size bits/screws you have on hand. it's posted if you search, 6 1/2 speakers CAN fit in your front doors, granted their mounting depth is less than 1 3/4 inches.. eitherwise the window won't shut/will hit your speaker magnet. ANY 6 1/2's fit in the rear deck, you just have to be able to mount them right, as space is VERY tight in the rear dash of a protege. a little finess, and you're in good shape. any more explaination than that, don't attempt to install them yourself, pay the 35 bucks and have a professional do it FOR you.
peace

 

Thanks for the help! I'm going to unscrew the door panel to see how much room I got to play around with... I bought a pair of clearance Sony Xplod 5 1/4" for $35 (last year's model xs-w1321). They have a mounting depth of 1 13/16", which is 1/16" above 1 3/4"!!! So we'll see if they fit or not... I'm thinking of returning these ones if I'm not satisfied with them...

I'm looking at purchasing a pair of Infinity 6002i 6 1/2" speakers for my fronts, but they have a mounting depth of 2 1/4". I've heard of people making an insert that will extend the mounting depth, in this case by half an inch. Is this possible? IF so could someone please provide a more detailed explanation on how this is done? Thanks so much guys!
