After paying all that money for a custom box enclosure for your Nissan 350z you then need a good subwoofer speaker for it. A good thing to add for your Nissan 350z custom box enclosure would be a KICKER CompVT Series Shallow Subwoofer Speaker. With the KICKER CompVT Series Subwoofer Speaker install on your 350z your custom box enclosure it will give you the perfect sound and bass. It also depends on how much bass wattage sound you think would sound great for your Nissan 350z. KICKER introduced a true high-performance subwoofer with a reduced mounting depth a few years back, and it was met with immediate success. Who wouldn't want a subwoofer that pounds insanely from the slimmest locations. The next generation of KICKER CompVT Series Subwoofer Speaker slides into door panels and other tight fits. Four options are available that deliver real KICKER bass and take serious power. The 12-inch KICKER CVT12 and 10-inch KICKER CVT10 easily handle 400 watts RMS (800w peak) without hesitation, and if you want to go even smaller, an 8- or 6.5-inch option hammers from the slimmest locations. Precise KICKER engineering allows the CompVT to pound with limited space. A special four-layer voice coil provides the KICKER CompVT the ability to work with serious amounts of power without the bulk.

The woofer's stiff, injection-molded, modified-spoke cone is shaped to provide maximum excursion from a slender basket, allowing the ideal amount of flex for better strength and durability. Space-saving features make for woofers with amazing mounting depths of less than 4-1/2 inches. A ventless, solid-pole design allows the KICKER CompVT to be mounted directly against the rear wall of its small sealed or vented enclosure. The spring-loaded binding posts are mounted differently than standard subwoofers to minimize size. Finally, a handy steel "clearance" adapter plate allows the removal of enclosure wall depth for further minimal spacing concerns. The cone's 360-degree back bracing, ribbed Santoprene surround, and Spiralead tinsel-lead technology help KICKER CompVT subwoofers sound spectacular. Perimeter venting, high-temp coil wire, double-stitching, and a logo trim ring around the steel basket's outer edges are all features that make KICKER CompVT Series Subwoofer Speaker the most reliable and best sounding subwoofers in the world. So forget those thoughts of having a factory speaker on your 350z and take a look at the KICKER CompVT Series Subwoofer Speaker today.
