CEA Compliant Legitimate Power Ratings
Peak 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 1,000 watts peak which is a lot of power for a small 8" subwoofer.
Program Power = The RMS power the way most middle of the road brands on the market rate their products. This sub can handle 500 watts program power. So for example a 500 watt RMS Hifonics amplifier will work perfectly with one of these.
CEA 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 250 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 compliant ratings.
We 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.
Description:
Rockville W8T4-S2 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-S2 subwoofers feature a 2-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-S2 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 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.

About Rockville Quality Control Procedures:
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.Description of KTA-200M:
PowerStack Installation
The KTA-200M follows Power Pack Amplifier, in compact size, easy installation and overall power. Both amplifiers, while designed to “stack” behind the iLX-W650, or similar 2-DIN radio, can also be used as standalone solutions in vehicles that don’t have space for a traditional amplifier.
Powerful Bass
The ratio of power to price is unmatched in the industry, as the KTA-200M doubles its power from 200 to 400 watts with Alpine’s DPP technology. During powerful, or “dynamic,” passages of music, DPP will adapt to the needs of the music by adjusting the gain of the amplifier and delivering bursts of power that match the peak demands of the music.
New to the KTA-200M, a voltage adapting input circuit is included to maintain the maximum source signal level without clipping. This ensures that the KTA-200M can continue to produce powerful, clean bass even at higher volumes and dynamic musical passages.
