    Swapping out the stock speakers. Already swapped the front door speakers.
    Any chance any one knows what size the speakers are in the sleeper?

    Try and use cruthcfield to see if they can match it, but I’m guessing 6x9 since that’s what I have but mine is a 2013

    Crutchfield only gives me the option to see what fits sprinters and M2 freightliners.
    I don't think Freightliner changed it since 2012. Ill order 6x9 and hope for the best, thanks.

    Truck is parked 40 minutes from my house and I'm home right now. Was hoping someone knew so I can order it today.
    Do you just measure them side to side and top to bottom?

    I forgot to mention what ever you are getting make sure your head unit can run it. I had an issue with my speakers and still waiting on to install an amplifier, as well new wires as my aftermarket head unit cuts off mid volume levels.

    Not looking for high volume, just a little cleaner sound. Old door speakers were 65 watt each, new ones i installed are 300 watt and already sound better. Just need a little bit of bass.
    I am shopping around for a double din android head unit to install later on. Will throw in an amp if it needs it.

    300 watts isn’t the actual rating on the door speakers and most likely around 65 watts rms You need to look at the RMS rating, and also the resistance in the speakers. as stock head unit usually runs on 4-8 ohms and running 4 speakers at 3 ohms would put it out of business. Even a aftermarket head unit is only going to be rated at 17 watts per channel RMS and they also have a resistance range they operate.

    so make sure you match everything up and an amplifier is going to be needed most likely.

    I would personally go with the same brand and model speaker as your doors to match the resistance and then look at a head unit that operates in that range so as to not run an amp if you don’t like it that loud. If you do need an amplifier I would make sure everything is OFC copper and not CCA. As well as double shielded RCA’s and speaker wires to reduce engine noise. Run the ground and power to the batteries directly and bypass the stock plug pins for those.

    When I choose the head unit Ill just find a professional to do all the stuff you just said lol. I am not an audiofile and don't really understand all of this.
    The door speakers were Panasonic trash. My phone speaker sounds better. Just swapped em out for cheap better replacements.
    If I have a problem after I install the rears I'll just swap back the old ones till I have an amp and head unit.
