Description of R-A75M:
The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers,, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.
PROPER SOUND STAGE
This new technology minimizes audible imperfections like excessive phase shift
and internal noise which can deteriorate sound quality.
NEXT LEVEL SYSTEM BUILDS
R-Series amplifiers have a built-in bandpass filter which lets you design an
active speaker set-up without a separate processor. Improve the sound quality of
component speakers by ditching your passive network. Avoid added phase shifts
and power losses by individually powering each component and assigning your own
frequency bands for the incredible sound you’re looking for.
THE LOUDEST FAMILY ON THE BLOCK
The “R” line of speakers and subwoofers have a heritage of sound quality you can
hear from a block away, and the newly added R-Series amplifiers are no
exception. Aside from their best-in-class performance, these amplifiers are
tuned to emphasize the characteristics of the R-Series speakers and subwoofers,
giving you that legendary R-Series experience.

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!

Description of RQB12:
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!

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 sub enclosures are backed with a full 90 day warranty, though it is unlikely that you will need to use it.
Complete Single Subwoofer Enclosure Installation Kit!
Includes:
- 10 Drywall Wood Screws (Wood screws are the type of screws; the screws are actually made of metal)
- 12 Feet of 14 AWG Blue Speaker Wire
- 2 Spade Terminals
This accessory package includes everything you need to install one subwoofer into an enclosure, and wire to connect the 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.
