    I just bought a 1999 GMC Ext Cab Diesel (90s body style) I would like to upgrade the factory speakers and find a place for some small subs. What size are the stock speakers? Anyone have a good idea for subs without takeing up much room?

    My buddy has a custom box with (2) JL audio 12w7's under his back seat in his 99' extended cab. bolted the amps behind the seat under the back window. He had to replace the back window with plexi glass because he cracked the glass. /forums/images/graemlins/cool.gif

    That is perfect, i am surprised they fit. Any chance you could do some quick measuring on the box size?

    Take a look over on www.crutchfield.com They have a speaker selector tool that will tell you what size speakers will fit in the stock locations. /forums/images/graemlins/cool.gif

    [/ QUOTE ] No because I don't talk to the guy very often because he is always busy and hard to get ahold of, besides call a local stereo shop and they will know what will fit because I'm sure they have done an extended cab before.

    You can get 10" or 12" woofers back there under the seat. I have had both. The best was 10" woofers in a downfire box. These boxes are readily available at stereo shops and fit very good with out taking up leg room. The best one I had was made of MDF and coated with bedliner. I think your front door speakers are 6.5" and the ones in the back are the plate style 4"x6". If I remember correctly those in the back are up on the pillar and very hard to get to and change.
