Video of dB14:

Description:

The dB14 is a class D monoblock high power amplifier with 4,000 watts peak output, 2,000 watts RMS output, and 1000 watts CEA-2006 rated power. All of the mono amplifiers in the dB series are 2 ohm stable. They are all CEA-2006 compliant, which makes it easy to compare this amplifier to other CEA compliant amps on the market. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. So we provided 3 ratings for all of our car amplifiers. We provided a CEA compliant rating, which you should use to compare this amplifier to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supplied an RMS rating that is not CEA compliant, but has become standard in the industry. You should use this rating when comparing with ratings from brands such as Hifonics, Earthquake, DB Drive, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the amp puts out at the loudest moments during a particular song.

One of the tricks to determine the real power of a car amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20 %. The dB14 features a Maxi fuse with a rating of 100 Amps. Although we rate these conservatively at 1000 watts CEA @ 2 ohms, this amplifier puts out more power than this!

This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, mute and delay soft start technology, a phase control switch, and a dashboard subwoofer control for added convenience. The dB14 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.

The RCA input accepts both balanced and un-balanced inputs. If there is potential inference in the car, the balanced input signal is less susceptible to noise.

The dB amps by Rockville use the top parts and components recommended by Rockville’s very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even dB of sound. We created them to be 2 ohm stable just like the world’s most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class.

Each and every amplifier we manufacture is tested twice. Once at the semi-finished PCB stage of production, and then another test is done at the final assembly. We also run age tests on them. After this is all done, we hire a 3rd party independent company unaffiliated with our factory or with us to go to the factory and inspect 20% of all the production items. We test the power, the controls, and over 20 other tests. We guarantee these amps will satisfy you. We are so confident in your satisfaction of this amplifier that we will offer you a 90 day money back guarantee. If this amp does not perform as well as you expected we will send you a pre-paid shipping label and give you all of your money back. This means if for any reason you want to return the amplifier back for a full refund within 90 days, you can! (Amp must be complete along with the box).

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 than 100 % copper. So the only way a cable would out-perform this one is if it were being advertised as a 4 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 4-gauge cable! Then look no further than the Rockville True-Spec RWK4-CU 4 Gauge Amplifier Wiring Installation Kit. This package includes everything you'll need to get your amplifier system powered-up correctly and at peak efficiency. All items included in this kit are top of the line.

The power and ground cables aptly named “Mega Power Cable” is 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 120-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 14-gauge speaker cable included in the 4-gauge kit can handle over 2000 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.
