CEA Compliant Legitimate Power Ratings
Power = Amount of power the sub can handle for a burst during the loudest point during a song. This number is not as important as the RMS
power. This subwoofer has 1,200 watts peak which is a lot of power for a 10" subwoofer.
Power = The RMS power the way most middle of the road brands on the market rate their products. This sub can handle 600 watts program power.
So for example a 600 watt RMS Hifonics amplifier will work perfectly with one of these.
Rated RMS Power = This is an official tested rating by a specific industry standard. This is the way the top brands in the industry such
as Kicker, Rockford, etc rate their items. This subwoofer is 300 watts RMS CEA rated. This rating is measured at a very specific distortion
level. You can feel confident matching this with a high end amplifier from Kicker, or Rockford, or any other high end brand that uses CEA
supply all 3 ratings so that you can compare prices of our product to any brand on the market and also so you can confidently match this
subwoofer to amplifiers from many other brands.
Rockville W10T4-S4 10" 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 W10T4-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 W10T4-S4 is CEA-2031 compliant and rated with an amazing 1200 watts peak and 300 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 are not happy with these, we will call tag them and take them back within 30 days of when you receive them for a full refund. On top of that you get a 1 year exchange warranty for any defects.
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.

The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a hassle free warranty.
