Description of XTHUNDER125.4:

Extreme Power
Continuing the Legacy that MTX Audio started almost 20 years ago with the development of the Thunder amplifier series, we introduce the next generation – XTHUNDER. These amplifiers are designed to deliver extreme power to the most demanding speaker system designs and are capable of driving subwoofers and full range speakers alike. The XTHUNDER125.4 four channel amplifier powers high wattage speaker systems with headroom to spare, all without added distortion or over-heating during long hours of loud play.

Built to Drive BIG Sub Systems
Capable of delivering 125W RMS power per channel into a 2-Ohm load, the XTHUNDER125.4 is ideally suited to power MTX Signature Series and THUNDER series speakers. This is made possible by using high grade materials and a never wavering dedication to precision workmanship. This is what allows the XTHUNDER Series to deliver exceptional sound quality and performance.

What's Under the Hood?
We start by using a class A/B amplifier topology to maximize power efficiency while delivering unmatched sound quality. This is all built on a dual sided circuit board with oversized copper traces that maximize electrical flow and minimize power loss before it gets to your speakers. Components are installed using surface mount technology making the circuit incredibly durable and vibration resistant allowing them to survive even when used in big bass systems.

Additional heat management is handled by the top cover which functions as a large surface area heat sink. This effectively dissipates built up heat so the amplifier runs cooler and can play louder longer. The chassis also includes removable side covers that create a stealth look when installed but also allow for easy access to connections and settings after mounting.

But the XTHUNDER125.4 isn’t just another pretty amplifier. It is loaded with features and enables full customization to ensure the best possible sound quality without distortion. Using the built-in, fully adjustable high and low pass filters, you are able to get exactly the sound you want from your speakers every time.

It also improves bass quality and eliminates those bad rattling and distortion sounds.

Installing Rockmat improves bass quality of the speaker and eliminates those bad rattling and distortion sounds.

Our Rockmat is built to the highest standards in this industry using 100% butyl rubber with a layer of heat resistant aluminum.  Butyl rubber is the same material high end speakers surround material is made out of.

Our sound dampening product uses 72mil of pure grade aluminum! Most products on the market use 50mil. Our product will absorb sound better than the competition. If a product does not specify how much material is being used, you should be very cautious about it! Every manufacturer should know what they put into their products! Also, other products on the market such as GTMAT for example use a mixture of asphalt in their products. They basically are manufacturing roofing material and calling it sound deadener. Their product will work OK, but not nearly as good as our Rockmat. Our Rockmat is made of butyl rubber and aluminum which is the same as many of the more expensive brands out there that sell for twice our price.. We do not cheat our customers. We only make top quality gear over here at Rockville!

Our Rockmat has an adhesive temperature range of -100F to 300F (-60C to 150C). Our adhesive is top of the line! It will stick for years and years! Each layer of our material reduces unwanted noise 5-8 dB! This is among the best ratings in the industry. Our product works as well or better than other high end brands! We did our testing and research.

We make all our models in 2 color options. You get the choice of black and silver. We decided to tattoo our logo all over the material to make sure our Rockmat has a cool look to it.

Installation Instructions:
Rockmat is a self-adhesive. Stick the Rockmat in your desired area. Rockmat is pressure sensitive so after you apply the material into your desired area; apply pressure to it. That is it! Installation takes only minutes! Please note our Rockmat is also easy to cut into the desired shape you need!

Video for Unboxing RWK42:

Description:

The Rockville RWK42 4 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 80 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 (2) sets of RCA cables.

Features:

• Rockville RWK42 4 Gauge 4 Channel Car Amplifier Wiring Installation Kit
• (2) 17 High Grade Twisted Pair of 100% Copper RCA Cable
• 17 4 Gauge Translucent Blue SuperFlex Power Cables
• 17 18 Gauge Blue Remote Cable
• 17 16 Gauge Clear Speaker Wire
• 3 4 Gauge Clear SuperFlex Ground Wire
• Gold Plated AGU Heat Resistant Fuse Holder
• 80 Amp AGU Gold Plated Fuse
• 7 Split Tube Loom
• Accessories Included: Wire Ties, Ring Terminals, Butt Connectors, Spades, and Grommets
• Soft abrasion proof insulating jacket allows for 100% improved flexibility
• PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F

The Rockville Difference:

Whenever you see the Rockville shield on a product you know that it has the stamp of approval. While other companies simply import products from China, Rockville manufactures the products in China to lower your cost but do so under American style supervision and quality standards to get you that USA quality that you want!

 

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, though it is unlikely that you will need to use it.

 

Great features and great quality make Rockville a great choice.
