CEA Compliant Legitimate Power Ratings

Description of W8T4S2:

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.

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.

Description of KTA-30MW:

PRODUCT OVERVIEW
With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys.

A TOUGH MINI AMP THAT PACKS A PUNCH
Get big amp performance in a compact, resilient package. With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW Weather Resistant Tough Power Pack is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys.

This small and efficient amplifier can be installed with an aftermarket or factory head unit while adding up to 600 watts of D.P.P. power. Its weather resistance makes the KTA-30MW a good choice for use in exposed installations like side-by-sides, boats, open-top vehicles, and motorcycles saddlebags.

A SOUND SYSTEM BOOST WITHOUT THE BIG SPACE COMMITMENT
The KTA-30MW is perfect for when you want to add subwoofer power but don’t have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and provides up to 600 DPP watts to the subwoofer of your choice.

DYNAMIC PEAK POWER
The KTA-30MW features Alpine’s exclusive Dynamic Peak Power (D.P.P.) technology which intelligently adjusts the gain to automatically adapt to musical needs. D.P.P. prevents the amplifier from clipping music signals by supplying up to double the power to support power hungry, rhythmic peaks like a snare drums, trumpets, or high-hat cymbals.

During these dynamic musical passages, D.P.P. instantly delivers bursts of power to rise to the peak demands of the music and very quickly rolls back down to maintain its efficiency.

WEATHER RESISTANT FORMAT
The KTA-30MW is ready for your adventures. It is weather resistant, rated at IP66 for protection again dust ingress and high-pressure water spray. Its rugged chassis and high-quality waterproof connector can be used in installations where it will be exposed to the outdoor elements.

HALF THE SIZE OF OUR SMALLEST TRADITIONAL AMPLIFIERS
The KTA-30MW measures just 9-3/16” (W) x 1-5/8” (H) x 3-3/4” (D), so its small footprint lets it fit where most amplifiers won’t, like under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue.
