Description of S-W8D4:
The S-Series subwoofers are designed with increased bass output and installation versatility
ADD BASS TO PRACTICALLY ANY VEHICLE
Don’t think you have room for a subwoofer? Think again. The new S-W8D2 and
S-W8D4 8” S-Series subwoofers have a shallow mounting depth of just 3-3/4” and
can be used in a sealed box enclosure as small as .15 cubic foot. It is perfect
for under seats, behind rear bench seats in trucks, or even in some door
applications.
POWER HANDLING
The 8” S-Series subwoofers are engineered with an improved voice coil allowing
the woofer to benefit from it's power rating of 300 watts.
CUSTOM-STAMPED STEEL FRAME
Each S-Series subwoofer uses a custom-stamped steel frame. These high-strength
frames were designed to withstand the rigors of the improved S-Series motor.
They have frame leg vents as well as a vented back plate to help cool the
subwoofer voice coil and motor parts, plus a shallow design to help fit in
smaller spaces.
PUSH-TYPE INSERT TERMINALS WITH DUAL VOICE
COIL JUMPER SYSTEM
The push-type insert terminals help reduce the installation time of the S-Series
subwoofers. Just strip the speaker insulation at the wire end, then insert the
bare wire into the hole of the spring-loaded push terminal.
STRONTIUM FERRITE DOUBLE-STACKED MAGNETS
The S-Series subwoofers use two strontium ferrite magnets stacked together, for
increased motor strength and excursion which ultimately leads to more bass
output.
CLEAN, CONCEALED MOUNT GASKET SYSTEM
The S-Series subwoofers have concealed mount gaskets, creating a clean, finished
appearance for any vehicle.
OPTIONAL GRILLES
All S-Series subwoofers are compatible with optional grilles (sold separately)
to provide added protection to the cone. The grilles feature a mesh design with
a S-Series logo badge. KTE-8G: For 8” S-Series Subwoofers

Description of Krypton M2:
The Krypton series of amplifiers by Rockville are engineered to be reliable and are packed with features. Whether you are a car audio competitor or just like to enjoy loud music we engineered and designed these amps from the ground up to give you great sound quality. You will notice the cool battery voltage display meter which looks great but also serves as a tool for you to know if your battery voltage is dropping which would affect your systems performance. We designed the amps to be able to last for many years even if you are playing them at max volume before clipping for extended periods of time.
Our favorite feature of the Krypton series is the bass remote that has a clipping indicator. This allows you to set the amp to max output before clipping on any song. This will protect your subs while you maximize SPL. What is nice about this is that you can set the gain level to max before clipping on any given song in real time! If you use a DD-1 or another tool, you are setting the gain on one song but the next song might have more headroom or might clip depending on the levels it was recorded at (this is referred to as crest factor in the engineering world).
We guarantee that this series of amplifiers will not only meet their Dyno Certified power but exceed their rated power.
Another feature we love about this is the bass equalizer. Most amps have this feature however not all bass EQ's are created equal. Some bass EQ's will just clip your subs to death. Our bass EQ circuitry will boost the proper frequencies in a way that sounds good and is safe for your subs. In addition you can always use the clip indicator on the bass remote to make sure you are not sending a clipped signal to your subs. Our amplifier is meant to give as much clean power to your subs as possible. Our voltage display allows you to make sure you are getting the proper voltage to your amp and our clip indicator on the remote will make sure you always send clean power to your subs. In addition we also guarantee the amplifier will output over the Dyno Certified so you can confidently match our amplifier with high-end subs and know what to expect!
What about sound quality and efficiency ??
This amplifier is engineered so well that it has an extremely low signal to noise ratio which means the sound will be super clean even at high volume levels. It also has a great efficiency rating so you don't have to draw too much power from your battery. We engineered this to have a high common mode rejection rating (CMRR). This means that the amp has the capability to block out engine noise signals. By rejecting unwanted noise the end result is the cleanest sound quality.
Once again, Rockville has stepped up its game with the all new Krypton series. Their is no other amp like it on the market. The all new Phenom V2 series is in our opinion the best series of amps for the price. Between the true power, the build quality, and the features, we are confident you will agree.

Complete Dual Subwoofer Enclosure Installation Kit!
Includes:
- 20 Drywall Wood Screws (Wood screws are the type of screws; the screws are actually made of metal)
- 20 Feet of 14 AWG Blue Speaker Wire
- 4 Spade Terminals
This accessory package includes everything you need to install two subwoofers into an enclosure, and wire your enclosure to your amplifier. This package is a top of the line accessory package which we put together and tested.
The drywall wood screws were hand selected by our installation experts because they drill into the enclosure very cleanly, without chipping the enclosure. The speaker wire is 14 gauge. This is way better than using 16 gauge. You can be 100 % sure that your enclosure will have a clean signal to the amplifier with this top of the line speaker wire. These spade terminals have also been hand selected by our installation experts to make the internal wiring simple, secure, and to run the audio signal cleanly.

Description:
The Rockville RWK41 4 AWG (American Wire Gauge) amp kit has the following differences 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!
