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 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 http://www.polkaudio.com/car/product.php?name=mm2084 Boston Acoustic ProSeries 8.5LF http://www.bostonacoustics.com/ca_product.asp?ProductID=97&CategoryID=17 Kicker CompVR CVR8 http://www.kicker.com/ShowPage.cfm?filename=compvrsub.html&menu=SUBWOOFERS My head unit is Alpine 9813.
