You have come to the right place! Please e-mail us your technical question, and our experts will send you links to our live ebay listings of the products that best fit your application. We have the ability to put together big systems, as well as low-priced systems that will sound great.
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 small 8" subwoofer.
Program RMS Power = The Program 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 Program RMS Hifonics amplifier will work perfectly
with one of these.
CEA
Rated 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 350 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.
Utilizing a sophisticated “High-BL” motorstructure
together
with a large-diameter,progressive-roll
spiderprovides
increased linearity and superior overall sound quality. A vented core magnet motorstructure
with extra thick back & top plates allows for full
voice-coil extended peak-to-peak excursion, creatingultra
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 W8K7-D2 is CEA-2031
compliant and rated with an amazing 1200 watts peak and 300 watts CEA 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 qualityonour
Rockville subs are just amazing. Our engineers who design the subwoofers are allin
inthe USA and
have over30 years
experience manufacturing car audio.

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 ofRXA-T1:
Check out this video
of the 4 channel version of this amplifier
Over the years, the
technology used to create audio amplifiers has grown by leaps and
bounds. We consider it our mission to use our expertise in
developing the latest
technologies and to bring you the absolute best sounding
amplifiers on the market at a reasonable price. From its clean,
sleek design to its high
quality components, you will be amazed at the quality and power
that these new Phenom amps offer.
The RXA-T1 is a 2 channel high power amplifier with 1,500 Watts
peak output, 750 Watts RMS output (2 x 375 @ 2 Ohms) and 500 Watts
RMS (2
x 250 @ 4 Ohms). You can also bridge the amplifier and
get
1 x 750 Watts RMS @ 4 Ohms. The CEA-2006 compliant rating is 125 x
2 @ 4 Ohms and 185 x 2 @ 2 ohms <1% THD. Most brands do not use
CEA compliant
ratings because quite simply they do not want you to be able to
compare their amps to others on the market. Over here at Rockville,
we want you to
be able to compare our amps to any brand on the market. For this
reason we are supplying you with multiple ratings. The CEA
compliant rating should
be used when matching up or comparing this amplifier to other CEA
compliant brands such as Kicker, Rockford Fosgate, Alpine, etc. We
also
supply an RMS rating which should be used when comparing with
great brands that are not CEA compliant such as Hifonics,
Earthquake, Powerbass, etc.
The peak rating is simply what the amplifier can hit for a split
second at the highest point of a song. This rating from any brand
is not really
important. RMS and CEA ratings truly are the most important.
This unit also features a high speed MOSFET power supply, studio-grade
bipolar output stage transistors and ELNA brand audiophile capacitors.
It has a fully adjustable 12dB/Octave cross over with differential
circuitry. High Level inputs, also referred to as Speaker Level inputs,
allow you to install the amplifier into your vehicle even if you do not
have any preamp outputs available. That means you can install this
amplifier to your factory or aftermarket receiver. Other features
include Auto-Start Smart turn-on (This
function senses when there is a signal from the head unit and
automatically turns on the amplifier hence no need to run a Remote
Turn-On wire), a fully adjustable 12dB bass equalizer, 2 ch/ 4 ch input
mode switch, mute and delay soft start technology, and a crossover
band-pass control. The RXA-T1 is protected by a full IC controlled
circuit and has professional peak limiter circuitry guaranteeing
distortion free musical playback at all levels.
The circuitry of this amplifier is a class A/B circuitry. Class A/B
is known
to have amazing sound quality. Pro audio amps usually all are
class A/B. Class A/B however is not known for its efficiency. To
make this amplifier
more efficient we simulated a class “G” amplifier. Class G is
technology that switches the rail voltage depending on how much
power is being used.
We have similar technology built into these class A/B amplifiers
which make these about 65-70% efficiency which is just amazing for a
class A/B
amplifier.
We are so confident that you will be extremely satisfied with this
amplifier that we are giving every customer a 90 day money back
guarantee.
So purchase the amplifier and try it for 90 days. If you are not
happy, we will call tag it and cover return shipping costs and
refund you all your
money back. (Amp must be complete with accessories and original
box please).

Description ofRWK81:
The
Rockville RWK81 8 AWG (American Wire Gauge) amp kit has the following
diferences over other amp kits on the market at this price point.
1. Our RCA cables are 100 % copper. These are top of the line RCA cables
2. Better
Resistance: The only thing that really matters with wires is the resistance
rating. This is a measurement of conductivity and how much signal is loss per
foot of wire. Since Rockville wires
are made with around 3 times as much copper as any other wire at this price
point, these wires had a much better resistance rating which means they will
transfer more power to your amps than the other brands.
3.
We do not cheat you on the thickness of the wire. These are standard
American wire gauge thickness. This is another reason our conductivity
is better than anything else at this price point. Other brands in the
market place write 4 gauge, but cheat you on the thickness. We are
honest about the thickness.
4.
The Rockville amplifier installation kits feature a new soft abrasion
proof insulating jacket. This rugged PVC outer jacket allows for 100%
improved flexibility over standard power cables making them extremely
easy to route through your vehicles interior, and it maintains
exceptional resistance to grease and oil. The PVC outer jacket can
with-stand an extreme temperature range of -40 to 220 degrees F.
The
RCA signal transfer cables included in this kit feature blue and silver
twisted pair technology in a clear outer jacket insulation skin. Not
only do the blue and silver wires look cool but they also provide
superior signal transfer with maximum noise suppression. They are 100%
copper to provide absolute lossless perfect signal transfer to your
receiver. This technology reduces interference, so your audio signal
flows clean and pure at all power levels.
This
kit also includes a massive 60 Amp AGU Gold Plated Fuse, so you can be
sure it will handle the all the DC power that your amp will need without
even the slightest loss of current. The included 7 split loom tube
provides protection for your power cable from the typically harsh
environment found under the hood of your car.
Audiosavings
product experts have tested this amp kit against many leading amp kits
on the market and were were impressed not only by the great looks but by
the quality of these Rockville installation kits as well. These kits
had a lower resistance rating than the other brands we compared and
tested them against. What this means is that Rockville manufactures
their kits with more copper than other kits at this price point,
ultimately providing your amplifiers with better and cleaner DC power,
so they work cooler and more efficiently. You will hear the difference a
Rockville installation kit will make!
One
other last thing worth noting about our kit compared to others. Our kit
cosmetically looks the best. It has blue power wire, clear ground wire,
and twisted pair RCAs with matching colors. This model includes (1)
sets of RCA cables.
