Have you noticed your headlights dimming to the beat when you hit those heavy bass notes on your car’s custom sound system? Cranking up the volume on your system can put inordinate amounts of stress on your vehicle’s electrical system. Most cars today cannot handle the high power demands of custom sound system components hence the need for a dependable and powerful capacitor. Enter the Rockville RFC30F Digital Hybrid Capacitor. This professional grade capacitor is built to handle even the most power hungry amplifiers delivering a surge of up to 20 volts of power when needed.
 
Rockville engineers have gone out of their way to design and put in your hands a high end capacitor at half the cost of our competitors similarly spec’d models. The RFC30F features a 3-digit super bright digital LED read out which displays the unit’s exact operating voltage to the decimal point. It comes equipped with heavy duty bolt down style platinum plated terminals which ensure a safe and solid connection. The built in IC Controlled circuitry alerts you if your voltage is too high (+17.5v) or too low (-10v). An automatic sleep feature helps the capacitor reserve power during lulls in volume levels, delivering it only as needed. With its sleek lines, modern styling and cool blue LED accents, the RFC30F will enhance the look of any sound system.
 
The reasonably priced RFC30F comes with a 90-day money back guarantee. With its high quality build and superb performance, its a definite step up and a must have for your car’s sound system.

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.
