    This is the sub enclosure I'll be installing in my car.

    These enclosures are designed to fit in the small areas on each side of the trunk. They are manufactured using fiberglass bonded to an MDF face – sized to accommodate most 8” sub-woofers. The outside is finished with a gray automotive felt and there is a quality gold-plated speaker-wire feed-through. The enclosures are held firmly in place using a nylon strap and snap assembly.

    • Installs in less than 10 minutes (assuming amplifier is already in place)
    • Can be removed in less than a minute to fit larger items – such a golf bag
    • Does not require removal or relocation of the tire tool-kit
    • Saves space in an already small trunk [​IMG]
    Specifications

    Type - Sealed Enclosure
    Volume - 0.38 ft^3 (0.33 - 0.35 once speaker is installed)
    Weight - 6 lbs (12 – 15 lbs once speaker is installed in enclosure)

    I plan on using Blaupunkt PA2150 to power the sub (400 wrms bridged 4 ohms)

    So far I have

    Polk Audio MM2084

    Boston Acoustic ProSeries 8.5LF

    Kicker CompVR CVR8

    My head unit is Alpine 9813. I listen to trance, rock, r&b if that matters.

    The amp is rated at 400 watts but it's wrms is 480 so I don't know if that's gonna work.

    Right now I'm leaning towards Boston ProSeries 8.5LF or the Polk Audio MM2084. Anybody have an opinion or a recommendation for another sub. TIA

    i put 2 Polk MM2124's in a lancer the other day powered off the polk/momo c500.1 and it sounded awesowe. great clarity and enough bass to rattle the entire car (literally). I would say the mm2084 ought to be a good fit for you.

    Well by that same rationale, the Polk wouldnt work either, as it is only rated at 200 watts...

    I modeled the Boston Pro vs. the Dayton Quatro and they actually have very similar parameters, and would have almost the exact same amount of output.

    NONE of those speakers handle 400wrms below around 80hz or so in that box. You will overdrive them all.

    The Boston would probably be the best choice if you plan on playing it ultra loud at full volume for extended periods of time, but then again, the quatro actually has the capability for a tiny bit more output.

    The RE8 would probably be the best choice out of all of the woofers listed for that 400 watt amplifier....

    I'd say either RE8 or the Elemental Designs 8" speaker, that thing is hella ballsy, sorry haven't heard the RE8 to compare it to...

    I've considered RE8 and Elemental Design e8A.44 but my amp will only work at 2 ohms non-bridged (2X200 watts).

    The maker of the box thinks that I should use single voice coil sub at 4 ohms, since the amp is stable at 4 ohms 400watts.
