Description:

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 channel / bridgeable mono model, 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).

Owner’s Manual

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 DJ/PA speakers are backed with a full 1 Year warranty, though it is unlikely that you will need to use it.

Description:

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 8 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.

Description for Rockville Enclosure:

The RQB12 Qbomb single 12" vented enclosure is an incredibly well-built and durable sub enclosure. This box is finished with a bedliner spray which hardens to make this box weather resistant as well as making it almost impossible to break. The bedliner finish is the same material that the back of a pickup truck is made of.

This speaker box is made in the USA with Grade “A” ¾” MDF wood and then finished off with a thick bedliner finish. This enclosure is made with precision cutting machinery by industry experts that have been making these enclosures in the USA for over 20 years. All Rockville enclosures come with a customized enhanced glue that is unmatched by any other manufacturer. The ¾” USA MDF is much stronger then any type of import wood. This will keep your box performing at an optimal level by not flexing and distorting your woofers. Your woofers will thank you! EVERY Rockville enclosure is not only glued at all joints but stapled as well. If that wasn’t enough we add a layer of silicon to every seam! This makes your Rockville enclosure rock even more!
