Description of X-W12D4:

OVERVIEW
The New X-Series subwoofers were developed from a sound philosophy we call Alpine ID – a focus on highly accurate components built for superior imaging. A triple stacked magnet surrounds an extended voice coil which allows a very long excursion resulting in huge air movement.

A specialized CRC pole with integrated cooling fins and an aluminum shorting cap reduce the lag of coil’s alternating movement while also providing cooling within the motor. The cone structure is suspended by two spiders and our patented H.A.M.R. surround.

The stability of the dual-spider along with the even unfolding of the multi-roll surround create incredibly linear cone travel, free of any unneeded movement that cause distortion.The powerful and efficient motor coupled with its highly-controlled suspension give the X-Series subwoofer the ability to create loud and accurate bass in a very small, sealed box.

Only requiring 1 cubic foot of air space (.55 for the 10”), the 12” X-Series subwoofer can reproduce frequencies down to 40 Hz before rolling off, leaving you with bass that digs deep and plenty of trunk space.

The new X-Series subwoofers are the X-W12D4 12-inch Dual 4 Ohm and the X-W10D4 10-inch Dual 4 Ohm.

CRITICAL EVALUATION OF IN-CAR SOUND
Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate sound systems from both the aftermarket and high-end OE manufacturers. Many systems today have incredible dynamic range and reach sufficient volume levels, but lacked the reality of instruments and spatial imaging.

As a result, Alpine ID was born, a sound philosophy that continues to inspire us to create a new level of sonic performance.

ALPINE: IMAGE DEFINED
Or Alpine ID for short, is the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage. It centers on developing matched sound systems with core components that work together to achieve greater realism in the sound stage while maintaining great dynamic range and accuracy.

BUILT TO MOVE TONS OF AIR
The 24mm Xmax is best in class and allows close to 2 inches of full cone motion. In order to create a powerful yet accurate subwoofer, we had to implement several technologies that keep the cone under control. Dual spiders ensure a rigid moving assembly while the HAMR surround provides long linear travel.

A shorting ring keeps the THD down while a custom heat sink integrated CRC pole and shorting cap keeps high magnetic force. These design aspects come together to produce incredibly precise, powerful bass.

EASY GRILLE AND TRIM RING INCLUDED
Taking design cues from tweeter development, we’re incorporating a twist-lock trim ring which allows easy attachment of the included metal mesh grill. With a simple twist, the trim ring locks into place, concealing the mounting screws and locking the optional grille into place. The trim can be installed with or without the grille.

THE PERFECT PAIR PERFECT POWER MATCHING
The X-Series amplifier, X-A90M, is the perfect amplifier for the job. Along with the 900w power matched specifications of both components, each were built under the same sound philosophy, Alpine ID. With a focus on musicality and sound imaging, the X-W12D4 is complimented by the amplifiers clean, low distortion output and >1500 damping factor.

Add the X-Series speaker to the system and prepare to experience a new level of in-car imaging.

We challenge anyone to put this wire to a resistance test against any other wire on the market with the same gauge. If our cable does not meet or exceed any other cable, even if it costs 3 times more, we will be happy to call tag the item and refund you in full. Why are we so confident ? This cable is 100% copper. You cant have a cable with more copper than 100 %. So the only way a cable would out-perform this one is if it were being advertised as a 0 AWG but they are giving you more wire than advertised. No brands selling 100 % copper cables actually do this.

We guarantee that this kit will compete with the most expensive amp kits on the market from Kicker, JL Audio, or any other top brands.

Maximum Power!
Looking for a wire kit that has 100% true specifications? A wire kit that uses 100% copper 0 gauge cable? Then look no further than the Rockville True-Spec RWK0-CU 0 Gauge Amplifier Wiring Installation Kit. This package includes everything you'll need to get your amplifier system powered-up correctly and at peak efficiency.

The power and ground cables aptly named “Mega Power Cable” are a no compromise power cable. Rockville’s engineering team over-built and designed the cables using thousands of strands of only true 100% oxygen-free, silver-tinned copper strands. The use of a proprietary special twisting process reduces “surface skin impedance loss” so that Mega Power cables have zero signal and power loss, delivering full power from your battery system to your amplifier even at lengths of 20 feet! The increased current flow and higher amperage carrying capacity will increase your amplifiers efficiency and keep your amplifier running cooler. The SuperFlex outer insulating jacket jacket makes installation and cable routing simple and easy. The 100% copper stranded wire is extremely tolerant of the hostile conditions found under the hood in vehicles and compensates for vibration, heat expansion and flexibility. This flexible and well shielded wire is crucial for getting through all of the nooks and passageways within the confines of a vehicle interior.

Some manufactures use all aluminum or mix a little copper with aluminum to give their cables the appearance of a “heavy-duty” cable. But not Rockville, our True-Spec 100% oxygen free, silver tinned copper eliminates corrosion, increases current transfer x 10, and won’t discolor over time.

The superior quality and materials of the Rockville 100% True-Spec amplifier installation kit is realized in the included accessories and cable workmanship. Included is a precision CNC cut full size ANL fuse housing, machined from solid brass and then 14K gold plated for superior signal transfer and complete with a matching gold plated 250-amp ANL fuse. The power cable is wrapped in 6 feet of durable nylon braided tubing to protect it from heat and chafing in the engine compartment. All installation accessories such as the ring terminals and spade connectors are nickel plated for superior signal transfer and durability.
 
CRYSTAL SQ AUDIO PLANAR SPEAKER CABLE
The speaker cable included in the Rockville True-Spec is also manufactured from 100% copper and woven in to a flat planner design and coated in our Super-Flex insulation so that it fits under and around your vehicles trim and carpet smoothly and without bulking up. With crystal clear sound quality these speaker cables deliver true audio fidelity from your car audio amplifier to your speakers. The 12 gauge speaker cable included in the 0 gauge kit can handle over 3000 watts of power without heating up or degrading signal quality.

CRYSTAL SQ RCA AUDIO INTERCONNECT CABLE
Designed and engineered to be the best sounding, best performing and best looking RCA cables available today. Each channel in the RCA cable is triple shielded first with dielectric internal insulators and then with a 98% coverage woven shield. All cables are manufactured of 100% oxygen free copper and feature twisted pair technology for superior noise rejection and pure sonic signal flow. The RCA plugs are shielded metal and feature a spiral cut outer ground ring with center split pin for precise and tight audio connections. The result of all this technology is noise free-noise rejection signal transfer for optimum sound quality. You will hear the difference these RCA signal transfer cables will make.

Description:

The Krypton series of amplifiers by Rockville are engineered to have the best reliability and 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 and great features. 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 we introduced 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 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 you 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 be giving over the rated Dyno Certified so you can confidently match our amplifier with high-end subs and know what to expect!

What about sound quality and efficiency though ??
Well glad you asked. This amplifier is engineered so well that it has an extremely low signal to noise ratio which just means the sound will be super clean even at high volume levels. It also has a good efficiency rating so you don't have to draw too much power from your battery. One other thing that is important is that 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 noises 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. In our opinion this is the best budget series of amps in the world. We actually enjoy this amp more then others that cost over 2 times the price.
