Rockville W8T4-S4 8” 1000 Watts Peak/500 Watts Program/250 Watts RMS CEA Compliant 4-Ohm Shallow Mount Car Subwoofer

W8T4S4

Description:

Rockville W8T4-S4 8" Subwoofers feature the thinnest mounting depths available making them the best shallow-mount driver's suitable for the most intricate bass installations. Deep bass that's made to fit where standard-sized subwoofers can’t. What else can you ask for?

The Rockville W8T4-S4 subwoofers feature a 4-Ohm single voice coil. These subwoofers are engineered to deliver serious low frequency response where space is limited. Whether installed behind the seat in a compact car, pick-up truck or in a motorcycle's saddlebags, make no mistake Rockville T4 subs will rock you! Utilizing a sophisticated “High-BL” motor structure together with a large-diameter, progressive-roll spider provides increased linearity and superior overall sound quality. A vented core magnet motor structure with extra thick back & top plates allows for full voice-coil extended peak-to-peak excursion, creating ultra deep bass response. Engineered with a special aluminum alloy high-temperature voice coil winding around the high-mass vented pole piece, helps to keep the woofers cool even when your music gets “hot”! The Rockville W8T4-S4 is CEA-2031 compliant and rated with an amazing 1000 watts peak and 250 watts RMS. That means you are getting 100% accurate RMS power ratings. These days lots of brands have competitions over how many thousands of watts they can write on the box of their items. The problem is you do not know what you are getting from them. It is easy to print a box that says 2,000 watts Max. Our subwoofers are rated in the same way that other famous brands rate their products. We also feel our manufacturing engineers are the best. The sound quality on our Rockville subs are just amazing. Our engineers who design the subwoofers are all in in the USA and have over 30 years experience manufacturing car audio.

If you want the best value for a shallow mount car subwoofer, and you want a great quality product that sounds great, and you also want hassle free return policies, then we highly recommend these Rockville T4 subs.

    Reviewed in the United States on October 1, 2023
    Used this to replace my factory blown sub in my 2003 Ford Expedition. I did install an aftermarket market amp that paired well with this sub. This sub hits pretty hard for a single 8. Sure it's not going to rattle the neighbors windows but definitely adds plenty of usable bass to my vehicle. I am impressed, had my doubts but I'm satisfied.
