Based in Modesto, California, ARC Audio is one of the few mobile electronics companies that still designs its amplifiers from scratch in the United States. The ARC Series trio of amplifiers represents a high-performance mobile audio amplification solution that incorporates features that aren’t available from competing products. Let’s take a look at what makes the ARC 1000.2, ARC 1000.4 and ARC 1000.6 truly special.

Premium Car Audio Amplifier Solutions

Combining the latest high-frequency Class-D driver technology with the engineering experience and acumen of the ARC Audio team, the three ARC Series amplifiers not only produce impressive amounts of power, but they also sound amazing. Each amplifier is housed in an identical custom-tooled cast-aluminum heatsink. Four large hex-head cap screws (that conceal the mounting locations) and seven machined fins across the top of the amp provide classy contrast against the textured matte black powder coat finish. All the connections and controls for the amp are placed along the bottom edge to simplify installation, configuration and calibration. Power connections are made using a chassis-mounted terminal block that accepts 4-AWG cable, and speaker and remote connections are on quick-release plugs. All amplifiers include on-board fusing, so there aren’t any surprises at installation time.

The ARC amplifier family includes the ARC 1000.2 two-channel amp that produces up to 500 watts per channel into a 4-ohm load, 600 watts into a 2-ohm load, and 1,200 watts when both channels are bridged to a single four-ohm subwoofer. The ARC 1000.4 is a four-channel amp rated at 250 watts per channel into 2 or 4 ohms, and each pair of channels can be bridged to provide 500 watts to a single 4-ohm load. The ARC 1000.6 produces a beefy 175 watts from each of its six channels at 2- or 4-ohm impedances. Each of the three channel pairs can be bridged to produce up to 350 watts into 4-ohm loads. Switches underneath each speaker connector change the internal supply voltage to optimize power delivery so that 2- and 4-ohm power production is similar.

Amplifier Common Features

All ARC Series amplifiers use balanced differential inputs capable of up to 4 volts of input with the default analog signal input card or up to 32 volts input with the optional IPS8.8 DSP card in place This higher level of signal input range is optimum for connections with factory amplified OEM systems and from some higher output OEM radios. At a quick glance, you’ll notice that there don’t appear to be many signal processing options on the ARC Series amplifiers. The ARC 1000.2 has a variable high- or low-pass crossover while the four- and six-channel amplifiers don’t have any crossovers at all. ARC Audio designed the analog signal processing portion of these amplifiers to be easily removable so that they can be used with any of the Pro-Series DSP processors from ARC Audio. If space is a limitation in your vehicle, each model of ARC Series amplifiers can he upgraded with the IPS8.8 Pro Series digital signal processor by simply removing the front end signal input module and replacing it with the IPS8.8. We took a close look at the eight-channel Pro-Series DSP platform here.

Each amplifier has an Auto Sense switch that allows your installer to choose from the remote turn-on connection, DC voltage sensing and a signal sensing option in order to activate the amplifiers when connected to an aftermarket source unit or a factory-installed sound system.

Microprocessor-Controlled Features

You will note that each amplifier has a micro-USB port on the front panel. This port exists even if you haven’t opted for the IPS8.8 processor upgrade and provides access to adjust the color of the logo on top of the amp and to change the Class-D switching frequency. Knowing that high-frequency switching inherent in all Class-D designs can occasionally interfere with radio reception, the engineers at ARC allow access to adjust the switching frequency from 323.4 kHz to 450 kHz. In the unlikely event your ARC Series amp does affect radio reception in your application, your installer can resolve the issue with a few taps on his computer keyboard. No other amplifier manufacturer in the car audio industry includes this feature.

Build Your Car Audio System with ARC Audio Amplifiers

Whether you need the ARC 1000.2 to power a subwoofer or are designing a four-way fully active entertainment system with an ARC 1000.6 and an ARC 1000.2, these amplifiers will ensure amazing sound and unparalleled flexibility when upgraded with an IPS8.8 processor.

The X2 Series speakers from ARC Audio are designed as a high-performance drop-in upgrade for the factory-installed speakers that came with your car or truck. This speaker series was designed based on feedback from ARC Audio retailers around the world to deliver impressive quality and value. With a total of nine models, including a pair of component sets, there is an X2 speaker for almost every application.

Basket Design and Installation Features

The X2 Series speakers were developed from scratch. Each speaker is based on a proprietary stamped steel basket. The baskets have spokes that are curved vertically and laterally to add rigidity to the design and prevent resonances. Integrated vents under the spider mounting plateau provide improved voice coil and top plate cooling while improving linearity at high excursion levels.

While conventional wisdom would suggest that a 6.5-inch class speaker would be suitable for all applications, the reality is that this speaker size has a variety of mounting and depth requirements. ARC Audio researched all the common applications and designed the X2 602 2-way coaxial and the woofer in the X2 6.2 component set with a 141.5 mm (5.57 inch) cutout requirement to fit into all applications. Mounting depth on these speakers is less than 2.4 inches.

Premium Design for Amazing Sound

While fit and flexibility are crucial, overall sound quality is the most important factor when choosing a speaker upgrade. ARC Audio’s North American transducer design team worked with its partners in Denmark to optimize the electromechanical design of each speaker.

The woofers on the X2 Series feature glass fiber-reinforced polypropylene cones for excellent rigidity and damping characteristics. The cones are attached to butyl rubber surrounds for reliable performance in all climates. The tweeters in the coaxial speakers feature a 20 mm (0.79 inch) silk dome design and are powered by strong Y-35 neodymium magnets. Integrated phase plugs on the tweeters help to smooth response at high frequencies. The X2 5.2 5¼-inch and X2 6.2 6½-inch component sets use a large, low-resonance 27 mm soft dome tweeter to help raise the soundstage in instances where the tweeter is mounted in the sail panels, dash or A-pillars. These same tweeters are offered as a stand-alone solution in the X2 1.0 set. All X2 Series tweeters include wool sound-absorbing material in the cavity behind the tweeter diaphragm to absorb rearward energy and reduce distortion.

The coaxial X2 speakers use high-quality polypropylene capacitors as a filter for the tweeters to deliver a smooth frequency response. The component sets feature upgraded 12 dB/octave networks to lower the crossover point while maintaining power handling.

Power Handling and Efficiency

Part of the design process for the X2 Series was to ensure that the speakers would work well when powered by an aftermarket radio that produces 15 to 22 watts and still be able to handle more than 150 watts when connected to one of ARC Audio’s large amplifiers like those found in the X2 Amplifier Series. ARC Audio invested significant effort in developing a voice coil that could handle high power levels while optimizing the overall design of each speaker for excellent efficiency in low-power applications. All speakers underwent extensive power handling tests with customized pink noise and dynamic sine sweeps at progressive power levels, and each failure point was addressed and upgraded until specific performance and power handling standards were met as the development process continued.

ARC Audio X2 Speaker Solutions

As mentioned, there are a total of nine solutions in the X2 Series. Offerings include the 4-inch X2 402, the 5¼-inch X2 502 and the popular 6.5-inch X2 602 round coaxial drivers. In terms of oval OEM sizes, the series includes the 4×6-inch X2 462, the 5×7-inch X2 572 and the 6×9-inch X2 692. We already discussed the 5¼-inch X2 5.2 and 6.5-inch X2 6.2 component sets and the X1 1.0 stand-alone tweeter sets. All X2 speaker solutions are sold in pairs and, because they’re designed as OEM speaker upgrades, do not include grilles. However, grille options are available from ARC Audio in a variety of sizes and colors.

If you’re interested in upgrading the sound system in your car or truck, drop by your local authorized ARC Audio retailer and ask for a demonstration of the new X2 Series speakers. We’re sure you’ll be impressed. For more information about ARC Audio and its products, visit its website and follow ARC Audio on Facebook, Twitter, Instagram and YouTube.
