The X2 series is a high-performance line of frequency-limited subwoofer monoblocks with a strapping circuit for combined output, and the Nighthawk is a compact full-range two-channel that measures 0.005% THD at its best. Arc is a brand judged on sound quality, and it is one we compete with.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Arc amp do I use for a subwoofer?\u003c\/h3\u003e\n\u003cp\u003eOne of the X2 monoblocks. The X2 650.1 makes 650W at 1 ohm for a single sub, and the X2 1100.1 makes 1100W at 1 ohm for more output. Both are frequency-limited to bass and midbass, both are 1-ohm stable, and both strap to double the power into one load. Match the amp's power at your wired impedance to the sub's RMS rating.\u003c\/p\u003e\n\n\u003ch3\u003eWhat does amplifier strapping mean on the X2 series?\u003c\/h3\u003e\n\u003cp\u003eStrapping is a master-slave mode that ties two identical amps together to drive one subwoofer load in unison, roughly doubling the output. A pair of X2 1100.1s makes about 2200 watts into a single sub. It is a growth path: start with one amp, add a matched second amp later without changing the driver.\u003c\/p\u003e\n\n\u003ch3\u003eIs the Nighthawk full-range?\u003c\/h3\u003e\n\u003cp\u003eYes. Unlike the X2 monoblocks, which are limited to bass and midbass, the Nighthawk runs full-range from 10Hz to 32kHz, which is what makes it a front-stage amp. It is 250W a channel at 4 ohm, bridges to 800W for a sub, and uses the same chassis as the Blackbird DSP amp without the onboard processing.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the Nighthawk have a built-in DSP?\u003c\/h3\u003e\n\u003cp\u003eNo. The Nighthawk shares the Blackbird chassis but leaves out the onboard DSP, so it is the choice when you already run a separate processor or a source unit with tuning. If you want the processing built into the amp, that is the Blackbird instead. Either way, plan a DSP into a reference active build.\u003c\/p\u003e\n\n\u003ch3\u003eDo you carry more Arc Audio amps than these?\u003c\/h3\u003e\n\u003cp\u003eYes. This collection is the amplifiers we stock in the amp category; the wider Arc Audio range, including speakers and subwoofers, is in the full Arc Audio collection.

A Blackbird DSP amp running a 3-way active front stage consumes all its channels for the front stage, leaving subwoofer and midbass amplification to be handled separately. Adding another DSP amplifier adds complexity, cost, and a second processor requiring synchronization. The Nighthawk adds output channels without adding another DSP: it takes the processed signal directly from the Blackbird's outputs, runs it through its own Infineon Class D output stages, and delivers that signal to additional drivers without interference or added processing latency.\u003c\/p\u003e\n  \u003cp\u003eThe crossover on the Nighthawk has a defeat switch precisely because of this use case. When running after a DSP processor that handles all crossover functions, the Nighthawk's onboard filter is bypassed entirely. When running the Nighthawk as a standalone amplifier without upstream DSP, the 50-500 Hz high\/low-pass filter with second-order Linkwitz-Riley alignment provides system integration capability without a separate processor.\u003c\/p\u003e\n\n  \u003cdiv class=\"arc-statgrid\"\u003e\n    \u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e0.005%\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eTHD Best Case\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e113 dB\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eSNR\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e500\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eDamping Factor\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e10.35 in\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eLength\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch3\u003eInfineon Output Stages and CTA-2006 Ratings\u003c\/h3\u003e\n  \u003cp\u003eThe Nighthawk uses Infineon Class D output stages, the same technology used in high-end professional audio amplifiers.

Arc Audio publishes all Nighthawk power ratings under CTA-2006, which means the 800 watt bridged figure is a real measurement, not a peak or marketing power claim. Arc Audio further notes that real-world output comfortably exceeds specification, consistent with their under-promise philosophy.\u003c\/p\u003e\n  \u003cp\u003eThe THD of 0.005% at the best operating point and 0.009% across 20 Hz to 20 kHz at 1 watt are genuine reference-class figures. For comparison, most automotive amplifiers in the Nighthawk's price range publish THD above 0.05% or simply avoid publishing THD at all. The 113 dB SNR and damping factor of 500 complete the picture of an amplifier designed for sound quality rather than just output.\u003c\/p\u003e\n\n  \u003ch3\u003eBalanced Differential Inputs\u003c\/h3\u003e\n  \u003cp\u003eThe Nighthawk uses balanced differential inputs rather than the single-ended RCA inputs found on most car audio amplifiers. Balanced inputs reject common-mode noise: interference that appears equally on both the positive and negative input conductors is cancelled by the differential circuit, while the audio signal on the hot conductor is preserved. In automotive environments where alternators, ignition systems, and switching power supplies generate interference, balanced inputs provide meaningful noise rejection. This is why balanced connections are standard in professional audio and why the Nighthawk's input architecture is a genuine performance feature rather than a specification checkbox.\u003c\/p\u003e\n\n  \u003ch3\u003eMatched Chassis, Clean System Integration\u003c\/h3\u003e\n  \u003cp\u003eThe Nighthawk uses the same extruded aluminum heatsink and chassis dimensions as the Arc Audio Blackbird DSP amplifier: 10.35 inches long, 6 inches wide, 2 inches tall. In an installation where the Blackbird and Nighthawk are mounted side-by-side or stacked, the visual result is a matched pair rather than two mismatched components. The high-current speaker connection plug system is shared between both amplifiers. The remote output on the Nighthawk allows it to trigger additional amplifiers in a system without requiring a separate remote wire from the source unit.\u003c\/p\u003e\n\n  \u003ch3\u003eMarine, Powersports, and Motorcycle Compatible\u003c\/h3\u003e\n  \u003cp\u003eThe Nighthawk's thermal range of -4 degrees Fahrenheit to 180 degrees Fahrenheit, start-stop compatibility down to 4.6 volts, and DC auto-detect turn-on make it suitable for motorcycle, marine, and powersports applications where operating conditions are more extreme than a typical car installation. The 4.6 volt minimum operating voltage handles the brief voltage drops that start-stop systems produce when the engine restarts, a failure point for amplifiers that require higher minimum voltage to operate.\u003c\/p\u003e\n\n  \u003cdiv class=\"arc-callout\"\u003e\n    \u003cp\u003e\u003cstrong\u003eInstallation summary:\u003c\/strong\u003e 2-channel Class D, 10.35 x 6.0 x 2.0 inches, 4 AWG power and ground, 3 x 30A ATM mini fuse, balanced differential inputs, high-current speaker plug output, selectable load switch (4 or 2 ohm bridged), stereo\/mono switch, adjustable crossover with defeat, remote output trigger, DC auto turn-on.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch3\u003eBuilt and Backed\u003c\/h3\u003e\n  \u003cp\u003eThe Arc Audio Nighthawk carries a 1-year warranty through authorized Arc Audio dealers.

The amplifier does not attempt to reproduce frequencies outside the subwoofer operating range, which means its power supply and output stage design are optimized for bass reproduction rather than being compromised by full-range requirements. The low-pass crossover is adjustable from 30 to 230 Hz and the subsonic filter runs from 10 to 80 Hz for ported enclosure protection. A bass boost of 0 to 12 dB centered between 30 and 125 Hz is included but should be used sparingly.\u003c\/p\u003e\n\n  \u003cdiv class=\"arc-warn\"\u003e\n    \u003cp\u003e\u003cstrong style=\"color:#f04657 !important;\"\u003eNot suitable for full-range or mid\/high-frequency speakers.\u003c\/strong\u003e The X2 650.1 bandwidth is 20-230 Hz.

The master amplifier provides all control functions (crossover, subsonic, bass boost, phase, gain) while the slave amplifier bypasses its controls and follows the master's signal. The slave input and slave output connections on each unit use RCA interconnects. This is not a bridging operation in the traditional sense: the X2 650.1 is already a monoblock and cannot be bridged. The strapping function doubles output capacity while maintaining the 4-ohm minimum load on the combined pair.\u003c\/p\u003e\n\n  \u003ch3\u003eBalanced Differential Inputs and OEM Integration\u003c\/h3\u003e\n  \u003cp\u003eThe X2 650.1 uses balanced differential inputs compatible with RCA line-level signals, balanced outputs from DSP processors, common-ground speaker-level outputs, and bridged-tied-load (BTL) outputs common to factory amplifiers. Included speaker-level input RCA pigtails incorporate a resistive voltage divider network that reduces the high-voltage output of factory amplifiers to an appropriate level for the X2's differential input stage. This makes the X2 650.1 directly connectable to factory audio systems without an external line output converter in most applications.\u003c\/p\u003e\n  \u003cp\u003eThe auto-detect turn-on provides two options: DC Detect monitors the RCA input for the DC offset common to factory BTL amplifiers and turns the X2 on when it appears, and Signal Detect turns the amplifier on when an audio signal is present.

The 1100.1 is 4 inches longer at 13.0 inches versus 9.02 inches on the 650.1, uses 3 x 30A fuses versus 2 x 30A, and steps up to Level 2 cosmetics with the extruded brushed-aluminum chassis and blue illuminated acrylic badge. Power output scales proportionally: where the 650.1 makes 350W at 2 ohms, the 1100.1 makes 600W. Where the 650.1 makes 650W at 1 ohm, the 1100.1 makes 1100W.

The master amplifier provides all control functions; the slave amplifier bypasses all controls except phase and follows the master's signal via the Slave In connection. The minimum strapped load is 4 ohms. This allows a dual-1100.1 system to reach 2200 watts at 4 ohms for a single high-power 4-ohm subwoofer or a pair of 8-ohm subwoofers wired parallel at 4 ohms.\u003c\/p\u003e\n\n  \u003ch3\u003eBalanced Differential Inputs and OEM Integration\u003c\/h3\u003e\n  \u003cp\u003eThe X2 1100.1 uses the same balanced differential input stage as the 650.1: compatible with RCA line-level, balanced DSP outputs, common-ground speaker-level, and BTL factory amplifier outputs. The included speaker-level input RCA pigtails with voltage divider allow direct connection to factory audio outputs in most OEM integration applications. DC Detect and Signal Detect auto turn-on modes eliminate the need for a dedicated remote wire.\u003c\/p\u003e\n\n  \u003ch3\u003eSubsonic Filter for Ported Enclosures\u003c\/h3\u003e\n  \u003cp\u003eThe adjustable subsonic filter from 10 to 80 Hz provides excursion protection in ported enclosure applications. At 1100 watts into a ported subwoofer enclosure, infrasonic content below the port tuning frequency will push the cone well beyond its mechanical limits without a subsonic filter in place. The filter should be set at or slightly below the enclosure tuning frequency in all ported builds. The low-pass crossover from 30 to 230 Hz handles the upper frequency boundary; the subsonic handles the lower boundary.\u003c\/p\u003e\n\n  \u003cdiv class=\"arc-callout\"\u003e\n    \u003cp\u003e\u003cstrong\u003eInstallation summary:\u003c\/strong\u003e 4 AWG power and ground, 3 x 30A ATC\/ATO on-board fuses, removable plug-style speaker terminals (12 AWG max), balanced differential RCA inputs with speaker-level pigtails included, DC Detect or Signal Detect auto turn-on, remote level control included, start-stop compatible below 8V, Slave In\/Out for master\/slave strapping.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch3\u003eBuilt and Backed\u003c\/h3\u003e\n  \u003cp\u003eThe Arc Audio X2 1100.1 carries a 1-year warranty through authorized Arc Audio dealers.

Arc Audio documents four configurations: four-channel stereo high-pass with subwoofer, three-way active with tweeter, midrange and subwoofer, three-way with passive mid and tweeter plus midbass and subwoofer, and bridged three-channel stereo with subwoofer. That range is what makes this amp worth its footprint. A builder who would otherwise install a four-channel plus a monoblock can do the whole system on one amp, one power run, and one ground.\u003c\/p\u003e\n\u003ch3\u003eTwo Bandpass Sections, Not Just High-Pass and Low-Pass\u003c\/h3\u003e\n\u003cp\u003eChannels 1 and 2 and channels 5 and 6 each have a full bandpass crossover section: high-pass, low-pass, and both together. Channels 3 and 4 have a high-pass with full-range bypass. Every low-pass and high-pass section except the fixed 12 dB per octave stages carries an X1 and X10 range multiplier, which moves the adjustment window from 50 to 500 Hz up to 500 Hz to 5 kHz. That is what allows a true active midrange band on channels 1 and 2 without an external processor. For DSP-based systems, every crossover switches to full-range and passes the signal untouched.\u003c\/p\u003e\n\u003cdiv class=\"arc-statgrid\"\u003e\n\u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e150W x 6\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eat 2 or 4 Ohm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e600W\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eBridged CH 5\/6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003e13.0 in\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eLength\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"arc-stat\"\u003e\n\u003cspan class=\"arc-statnum\"\u003eLevel 2\u003c\/span\u003e\u003cspan class=\"arc-statlabel\"\u003eChassis\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eLoad Select: Adjustable Rail Voltage\u003c\/h3\u003e\n\u003cp\u003eChannels 1 and 2 and channels 3 and 4 each have a Load Select switch that changes the amplifier's internal rail voltage to match the load. In the Under 4 Ohm position, the amp makes full power at 2 ohms stereo or 4 ohms bridged. In the Over 4 Ohm position, it makes full power at 4 ohms stereo or 8 ohms bridged. This is why the amp holds 150 watts per channel across both impedances instead of dropping output on higher-impedance loads the way a fixed-rail design would.\u003c\/p\u003e\n\u003cdiv class=\"arc-warn\"\u003e\n\u003cp\u003e\u003cstrong style=\"color: #f04657 !important;\"\u003eSet the Load Select switches before the first power-up.\u003c\/strong\u003e Running the amplifier with the Load Select switches in the wrong position can damage it.

A separate master switch selects between four-channel stereo and bridged two-channel operation. In bridged two-channel mode, input 1 feeds the output of channels 1 and 2 and input 2 feeds channels 3 and 4, with the channel 1 and 2 crossover and gain controls governing the signal.\u003c\/p\u003e\n\u003ch3\u003eBalanced Differential Inputs and OEM Integration\u003c\/h3\u003e\n\u003cp\u003eThe X2 1200.6 uses a balanced differential input stage compatible with unbalanced RCA, balanced DSP outputs, common-ground speaker-level outputs, and the bridged tied load outputs common on factory head units. Included speaker-level RCA pigtails carry a resistive divider network molded into the RCA end, which drops a high-power factory signal to a usable level without an external line output converter. DC Detect and Signal Detect auto turn-on modes monitor the channel 1 input and remove the need for a dedicated remote wire.\u003c\/p\u003e\n\u003ch3\u003eLevel 2 Cosmetics\u003c\/h3\u003e\n\u003cp\u003eThe 1200.6 carries Arc Audio's Level 2 cosmetic package: a silver brushed-aluminum hairline extruded shroud and an acrylic center badge that illuminates blue in normal operation and flashes diagnostic fault codes when something is wrong. The badge rotates in 90-degree increments to read correctly in any mounting orientation. All tuning controls sit under the removable shroud, so the finished install shows no exposed adjustment pots.\u003c\/p\u003e\n\u003ch3\u003eFront-Panel Diagnostics\u003c\/h3\u003e\n\u003cp\u003eThe illuminated badge doubles as a diagnostic display.

On a six-channel amp driving a full active system, being able to tell which side of the amp faulted without pulling panels saves real diagnostic time.\u003c\/p\u003e\n\u003cdiv class=\"arc-callout\"\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation summary:\u003c\/strong\u003e 4 AWG power and ground, 3 x 30A ATC\/ATO on-board fuses, removable plug-style speaker terminals (14 AWG max on channels 1 through 4, 12 AWG max on channels 5 and 6), balanced differential RCA inputs with speaker-level pigtails included, DC Detect or Signal Detect auto turn-on, remote level control included for channels 5 and 6, start-stop compatible below 8V, 13.0 x 6.268 x 2.162 in.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eBuilt and Backed\u003c\/h3\u003e\n\u003cp\u003eThe Arc Audio X2 1200.6 carries a 1-year warranty through authorized Arc Audio dealers.
