    I'd like to upgrade stock Volvo speakers. Anyone knows what size they are (I've got 6 total)? Anything you'd recommend? Thanks in advance!

    The stock ones are 5.25 I believe and dash is 3.5, I've replaced them with 6.5 in and they fit and the dash ones if you trim a little you can fit a 4 in and still put the covers back on. I would recommend some pioneer stuff and if you go aftermarket speakers you have to replace headunit to notice any difference.

    I see this is an old thread, but if you have a factory amplifier in the truck replacing speakers can be rather troublesome due to the ohm rating of the amp.

    Don't know if your truck has one. I know all 780's do. If you do my guess is it's under the bed. Black box will sau DELCO on it
