    Default How much air space is in driver's side rear compartment of 1st Gen Tundra DCs?

    How much air space / volume is in the driver's side rear compartment under the back seat of 1st Generation (through 2006) Tundra Double Cabs? I'm trying to decide between locating one or two 8" subs in there. I've seen the space listed at many different volumes while reading through searches. Has anyone measured that space and gotten an accurate reading? I did some fuzzy math and came up with .3125 cubic feet, but I think that's low because pretty much everyone else I've seen is listing a larger number for that space. I'll be getting the Polk MM840 sub(s) which require an ideal space of .35 per sub. I'm also trying to decide on, if I get two, whether I need to seal off the subs from each other with a center divider. Thoughts?

    Thanks!
    Drew

    two will be fine, if you get your enclosure built and they dont have enough output, put some polyfill in them to slow the backwave of the subs down to fool them into thinking they are in a bigger enclosure.

    two subs seems to be the average in those DC's

    hope that helps.

    Yep, thanks Zapco. Would you split the space in two or leave it as one big shared space for two subs?

    Anybody know the air space in the compartment?

    2 8s will fit perfect in the longer of the two storage spaces, keep the other one for either storage or whatever else you want to do with it. get some packing peanuts and fill the compartment, then put them in a box and measure the volume. it cant be more than a few cubic feet

    most all 8 in subs generally require the same amount of airspace....

    just with the higher end speakers the measurements have to be much more precise or your wasting your money....

    The Polk MM840 'requires' .35 cubit feet per sub ideally. Would y'all split up the space or let them share air space?

    Anybody measured the compartment under the driver's side compartment for volume?

    thats a good sub, im contemplating runnin a few of them.

    they can share or you can separate them, just depends on how you set them up. but sharing is easier because you only have to fabricate a single enclosure

    I'm planning on pairing a couple MM840s with Polk MM6501 components in the front and MM651 coaxials in the rear... all powered by a Precision Power PPI P900.5 amp (very similar to the Polk D5000.5, but slightly more powerful (particularly on the sub channel) and cheaper). Should be a nice setup.

    Still would like to know the measured size of the rear compartment if anybody knows...

    Leaning more toward the JBL MS-62C components now... to be paired with the JBL GTO804 subs. Not sure about for the rear doors though, as there aren't any MS Series coaxials that I can find. Anybody have any recommendations there? Closest I can find are the JBL P662.

    a decent coax will be fine for rear fill,you shouldnt have to spend over 80 bucks (full retail that is)...

    the front components will drown them out, unless you want to just be "loud". then run the same speakers as the front.

    Well I got the 2 840's hooked up in .7 enclosure, they sounded kinda weak at first because I ran out of time and couldn't play around with the gains and crossovers. Had time today and wow they sound good and hit hard. I thought the door speakers would outrun the subs and that doesn't seem to be the case. I have to ease off a bit and let the speakers break in for awhile before I can see how far they can go.
    I was expecting really tight bass and weaker lows (which is how every small sealed enclosure I've had played but those subs were cheaper). These things play lows really well and when they hit low hz they move like crazy. I noticed that the 840's have a huge Xmax compared to most other subs, so that maybe the reason.

    If you do decide to go with the 840's you will be very happy.
    As for the doors, the MM's sound good but I'm not as impressed as I am with the subs (maybe that will change with some more tuning and break in).

    speakers need at least 40 hrs of break in time before they really shine.....
