(2)&nbsp;Rockville W10T4-S4 10&quot; Shallow Mount Car Subwoofers Totaling 2400 Watts!&nbsp;<br>
CEA Compliant Legitimate Power Ratings<br>
<br>
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 1,200 watts peak which is a lot of power for a 10&quot; subwoofer.<br>
<br>
Program Power = The RMS power the way most middle of the road brands on the
market rate their products. This sub can handle 800 watts program power. So for
example a 600 watt RMS Hifonics amplifier will work perfectly with one of these.<br>
<br>
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 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 compliant ratings.&nbsp;<br>
<br>
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.&nbsp;</font></span><br>

<p>Rockville W10T4-S4 10&quot; Subwoofers feature the thinnest mounting depths
available making them the best shallow-mount&nbsp;driver's&nbsp;suitable for the most
intricate bass installations. Deep bass that's made to fit where&nbsp;standard-sized
subwoofers can��t. What else can you ask for? <br>
The Rockville W10T4-S4 subwoofers feature a 4-Ohm single&nbsp;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&nbsp;motorcycle's&nbsp;saddlebags, make no mistake Rockville T4? subs will rock you!<br>
<br>
Utilizing a sophisticated ��High-BL�� motor&nbsp;structure together with a
large-diameter,&nbsp;progressive-roll spider&nbsp;provides increased linearity and
superior overall sound quality. A vented core magnet motor&nbsp;structure with extra
thick back &amp; top plates allows for full voice-coil extended peak-to-peak
excursion, creating&nbsp;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��!<br>
