The M5-1000X1 is a monoblock subwoofer amplifier with a single Class-BD channel delivering up to 750W RMS at 2-ohm, designed exclusively to drive a subwoofer. Its frequency response is limited to 30Hz-245Hz and it features only a low-pass crossover and infrasonic filter. The M5-800X4 is a 4-channel full-range amplifier delivering 100W x 4 at 4-ohm across a 10Hz-50kHz frequency response, suited to powering speakers rather than a subwoofer. In most full marine audio builds, both amplifiers are used together. What subwoofer impedance gives the best output from the M5-1000X1? The M5-1000X1 delivers its highest rated continuous output at 2-ohm (750W RMS) and its highest dynamic output at 1-ohm (1000W dynamic). At 4-ohm, rated continuous output is 500W RMS. For the best balance of output and reliability in a marine environment, pairing the M5-1000X1 with a 2-ohm or dual voice coil subwoofer wired to 2-ohm is recommended. Is the M5-1000X1 suitable for saltwater marine environments? Yes. The M5-1000X1 carries IPX6 water intrusion rating and full Element Ready certification with integrated harness and panel seals, protecting it against water jets from any direction, UV radiation, corrosion, dust, vibration, and temperature extremes. It is designed for both freshwater and saltwater marine applications. What does the infrasonic filter do and should I enable it? The infrasonic filter attenuates frequencies below 30Hz at 12dB/octave on the output channel. Subsonic content below this threshold cannot be heard but can cause excessive cone excursion in subwoofer drivers at high output levels, risking damage over time. Enabling the infrasonic filter is recommended for most marine subwoofer installations, particularly at high volumes or when the source material may include subsonic content. What fuse is required for the M5-1000X1 and is it included? The M5-1000X1 requires a 70A MAXI fuse (Littelfuse part number 0299070). Note this is a 70A fuse - different from the 80A MAXI used on the M5-800X4 and M5-1500X5. The fuse is not included in the box and must be sourced separately. Install it as close to the battery as possible in the 8 AWG power supply line.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.

The M2-500X1 is a 500W mono Class-D marine amplifier from the M2 Element Ready series, rated at 300W at 4-ohm and 500W at 2-ohm. The M5-1000X1 is a 1000W mono Class-BD marine amplifier from the premium M5 series, rated at 500W at 4-ohm, 750W at 2-ohm, and 750W at 1-ohm, with IPX6 water intrusion rating, greater than 80% efficiency, and the PRESET feature for UTV kit compatibility. The M2-500X1 is the more accessible option for builds where 500W output is sufficient; the M5-1000X1 is the step up for higher output requirements and premium marine protection. What is Rollback Protection and when does it activate? Rollback Protection is a circuit that dynamically reduces the amplifier's output demand during sustained high-output conditions to prevent thermal stress on the output devices. Unlike a hard protect shutdown, Rollback Protection manages the amplifier's workload in real time, allowing it to continue playing while protecting the internal components from damage during extended periods of high volume. Does the M2-500X1 need a dedicated remote turn-on wire? Not necessarily. The M2-500X1 features Auto-Sense turn-on, which activates the amplifier automatically when it detects a high-level (speaker) input signal. This removes the need for a dedicated remote wire when integrating with OEM or aftermarket radios that don't have a separate remote output. An Auto-Sense bypass switch is also included for vessels with Retained Accessory Power (RAP) systems. Is the variable infrasonic filter adjustable and why does the range matter? Yes. The infrasonic filter is variable from 15Hz to 40Hz at 12dB/octave. A wider adjustment range gives more flexibility to protect different subwoofer types - drivers with a lower resonant frequency (Fs) benefit from a lower filter setting, while those with a higher Fs are better protected by a higher filter cutoff. This is more versatile than a fixed 30Hz infrasonic filter found on some amplifiers. What fuse does the M2-500X1 require and is it included? The M2-500X1 requires an 80A fuse. The fuse is not included in the box and must be sourced separately. Install the fuse as close to the battery as possible in the 4 AWG power supply line to protect the wiring in the event of a short circuit.

Maximum BOOM for Your Buck. Marine-Tough to the Core. Product Overview The Rockford Fosgate PM1000X1bd is a 1,000 Watt Class-BD mono amplifier purpose-built for marine, motorsport, and powersports environments where maximum bass output and genuine weather protection are non-negotiable. Delivering 300W x 1 at 4 ohms, 500W x 1 at 2 ohms, and a full 1,000W x 1 at 1 ohm, this is the dedicated subwoofer powerhouse of the Punch Marine amplifier range. What makes the PM1000X1bd different from a standard Class A/B mono amp is its Class-BD circuit topology delivering 75–80% efficiency ratings compared to the 20–60% typical of traditional Class A/B designs. That means more of your electrical power becomes bass output, less of it becomes heat. Combined with a frequency response optimised for 20 Hz to 250 Hz, this amp is exclusively calibrated for mid-bass speakers and subwoofers no wasted bandwidth, no compromises. Its 1-ohm stability makes it easy to wire a pair of 4-ohm DVC subwoofers or a quad configuration of 2-ohm DVC subwoofers directly, without needing a complex impedance calculation or risking amplifier damage. Rockford Fosgate's Element Ready™ construction handles the rest marine-grade two-part epoxy conformal-coated PCB and corrosion-resistant stainless steel hardware keep the PM1000X1bd performing reliably through saltwater spray, corrugated outback tracks, high humidity, and Australian UV. Key Specifications 1,000W total power output (CTA-2006 compliant) 300W x 1 at 4 ohms | 500W x 1 at 2 ohms | 1,000W x 1 at 1 ohm Class-BD circuit topology 75–80% efficiency rating 1-ohm stable monoblock; dedicated low-frequency output only Frequency response: 20 Hz – 250 Hz (±1 dB) THD+N: Less than 1% Input sensitivity: 150mV – 12V (low- and high-level) Low-pass crossover: 50 Hz – 250 Hz @ 12 dB/octave Butterworth Infrasonic filter: 28 Hz @ 12 dB/octave Butterworth (subsonic protection) All-Pass: No (low-frequency only) On-board Punch EQ: Bass +0 to +18 dB @ 45 Hz RCA pass-through outputs Optional remote Punch Level Control (PLC2) compatible Marine-grade two-part epoxy conformal coating on PCB Marine-grade stainless steel hardware Element Ready™: Dust, UV, Temperature, Water, Corrosion & Vibration rated Recommended fuse: 140A x 1 (not included) Max current draw: 130A at 13.8V sinewave 2-year manufacturer warranty Features & Benefits Class-BD Technology Efficiency That Translates to Real Bass Class-BD amplifiers achieve 75–80% power efficiency, compared to the 20–60% typical of Class A/B designs. That gap matters  it means more wattage reaches your subwoofers rather than being lost as heat, your electrical system works less hard, and the amp runs cooler in sealed installations. At 1,000W into a 1-ohm load, this efficiency advantage is the difference between a hot, straining amp and one that holds output all day on the water. 1-Ohm Stable Wire More Subs Without Compromise The PM1000X1bd's 1-ohm stability opens up multi-subwoofer configurations that would stress or destroy standard marine mono amps. Run two 4-ohm DVC subs wired in parallel per voice coil (final load: 1 ohm), or four 2-ohm DVC subs in series-parallel (final load: 1 ohm). Maximum cone area, maximum output, one compact amplifier. Dedicated Low-Frequency Design No Wasted Bandwidth With a frequency response of 20 Hz to 250 Hz, the PM1000X1bd isn't trying to be everything. It's calibrated exclusively for subwoofers and mid-bass drivers, with no all-pass mode and no high-frequency reproduction. Every watt is focused exactly where it needs to be. Infrasonic Filter at 28 Hz Sub Protection Built In The onboard infrasonic filter rolls off frequencies below 28 Hz at 12 dB/octave. This protects subwoofer cones from damaging over-excursion caused by ultra-low frequency content (boat hull resonance, port noise, corrupted audio files) critical for vented subwoofer enclosures and high-excursion marine subs in open-air environments. Marine-Grade Element Ready™ Construction Two-part epoxy conformal-coated circuit boards and corrosion-resistant stainless steel hardware provide full protection against the saltwater, humidity, UV radiation, and mechanical vibration that destroys standard car audio gear in marine and motorsport environments. This isn't a rebadged car amp it's genuinely built for the conditions Australian boaters, UTV riders, and 4WD tourers encounter. C.L.E.A.N. Gain Setting with LED Indicators Calibrated Level Eliminates Audible Noise. Onboard colour-coded LEDs (Blue: <0.5% THD | Violet: 1% THD | Red: 10%+ THD) guide precise gain matching between your head unit and amplifier maximising clean output headroom and protecting subwoofer voice coils from clipping distortion. High-Level Input with Auto Turn-On Accepts speaker-level signals directly from factory (OEM) head units no line output converter required. Auto Turn-On powers the amp automatically at ignition. Ideal for Aussie utes, 4WDs, tinnies, and UTVs running factory head units where aftermarket RCA outputs aren't an option. RCA Pass-Through Outputs Loop the signal from the PM1000X1bd to a separate full-range amplifier without signal degradation. Run the PM1000X1bd exclusively on subwoofers, and daisy-chain a PM400X4 or PM300X2 for full-range speakers from the same source. Optional PLC2 Remote Level Control PLC2-ready for driver-seat subwoofer level adjustment (sold separately), complete with an input clip indicator for real-time gain monitoring while underway. MEHSA³ Cast Aluminium Heatsink Maximum Efficiency Heat Sink Application (MEHSA³) construction delivers up to five times better heat transfer than conventional mounting techniques critical for a 1,000W mono amp installed in a sealed marine cavity or under a ute seat where airflow is limited.

For maximum output at 1 ohm, wire two 4-ohm DVC subwoofers with each voice coil pair connected in parallel, giving a final 1-ohm load. Alternatively, four 2-ohm DVC subwoofers wired in series-parallel also achieve a 1-ohm final load. Always verify total impedance before powering on. Can the PM1000X1bd be used for full-range speakers? No. The PM1000X1bd has a dedicated low-frequency response of 20 Hz to 250 Hz with no all-pass mode. It is designed exclusively for subwoofers and mid-bass drivers. For full-range speaker amplification, pair it with a Rockford Fosgate PM400X4 or PM300X2 using the RCA pass-through outputs. What is Class-BD and why does it matter for marine installs? Class-BD amplifiers deliver 75–80% power efficiency compared to 20–60% for traditional Class A/B designs. In a sealed marine cavity or under a ute seat, this means less heat generated per watt of bass output keeping the amp cooler, reducing strain on your electrical system, and extending the life of the install. What does the infrasonic filter do and do I need it? The 28 Hz infrasonic filter rolls off damaging subsonic frequencies that human hearing can't detect but that over-excite subwoofer cones particularly in vented enclosures or open-air marine installs. It is active by default and provides essential cone protection, especially important for high-excursion marine subs used in boats where hull resonance can generate problematic ultra-low frequency content. What warranty applies to the PM1000X1bd in Australia? The PM1000X1bd carries a 2-year manufacturer warranty. Australian warranty terms are administered through the authorised local distributor confirm coverage at point of purchase, as Rockford Fosgate's published US warranty applies only to products purchased via US-authorised dealers.

Serious Bass. Compact Package. Built to Survive the Elements. The Rockford Fosgate PM500X1bd is a 500 Watt Class-BD mono amplifier engineered for marine, motorsport, and powersports environments where dedicated subwoofer power and genuine weather protection are the brief. Delivering 150W x 1 at 4 ohms, 300W x 1 at 2 ohms, and a full 500W x 1 at 1 ohm, it sits in the sweet spot of the Punch Marine mono range more than enough to drive a serious subwoofer setup without the electrical demands or physical footprint of a kilowatt-class amp. Like its bigger sibling the PM1000X1bd, the PM500X1bd runs Rockford Fosgate's Class-BD circuit topology, achieving 75–80% power efficiency compared to the 20–60% typical of Class A/B designs. That means cleaner bass, less heat generated per watt, and reduced strain on your boat or vehicle's electrical system. Its 1-ohm stability lets you run two 4-ohm DVC subwoofers or four 2-ohm DVC subs without any complex impedance gymnastics, and its frequency response is locked between 20 Hz and 250 Hz every watt is dedicated to the low end where it matters most. Rockford Fosgate's Element Ready™ construction marine-grade two-part epoxy conformal-coated PCB and corrosion-resistant stainless steel hardware keeps it performing reliably through saltwater, humidity, outback dust, and relentless Australian UV.
