Couldn't Load Pickup availability
The Helix P ONE MK2 is a Class D mono subwoofer amplifier delivering 1,500W RMS at 1 Ohm (up to 1,800W RMS), with an optical digital input and High-Res capability. It belongs to Helix's premium P series amplifier range.
This listing is for the P ONE MK2. Helix also offers mono subwoofer amplifiers in the M series, including the Helix M One (up to 600W RMS) and the Helix M One X (1,030W RMS).

HELIX P ONE MK2: raw power, total control
The P ONE MK2 delivers 1,500W RMS at 1 Ohm (up to 1,800W RMS), making it a strong match for any subwoofer configuration, including two 2-Ohm subwoofers wired in parallel. Its large damping factor keeps tight control over woofer movement at all power levels.
High-Res Audio and a fully digital signal chain
With a frequency range extending to 40 kHz, a high signal-to-noise ratio and very low THD, the P ONE MK2 meets High-Res Audio standards and can be used as a full-range amplifier as well as a subwoofer amp.
The optical digital input accepts signals up to 96 kHz via light conductor, providing a ground-isolated, interference-free signal path. A 32-bit BurrBrown D/A converter handles analogue conversion. This makes the P ONE MK2 a natural pairing with Helix DSP amplifiers that feature an optical digital output, such as the HELIX P SIX DSP ULTIMATE.
Extremely high power density with particularly compact dimensions
The P ONE MK2 packs more power into a smaller enclosure than any other Helix amplifier. This is made possible by an efficient Class D design that keeps heat dissipation exceptionally low, allowing the compact chassis to handle sustained high-power output.

About the Helix P811002
From our tech experts at CEN
A monoblock subwoofer amplifier, rated at 1500w RMS.
Who it suits
Anyone adding a subwoofer to a processed system and wanting the bass driven properly.
Our tech experts advise
Matching matters more than headline watts: the amplifier has to suit the drivers, the gains want setting with a meter, and the power feed needs fusing at the battery on the correct gauge. Installation and tuning are priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: How much power does the Helix P ONE MK2 deliver?
A: Helix rates the P ONE MK2 at 1,500W RMS into 1 Ohm, with up to 1,800W RMS available. It is a perfect match for 2 x 2 Ohm subwoofers wired in parallel to a 1 Ohm load.
Q: Does the P ONE MK2 have a digital input?
A: Yes. It has an optical SPDIF input that accepts signals up to 96 kHz, converted by a 32-bit BurrBrown D/A converter. An SPDIF Direct In switch routes the digital signal directly to the power stage.
Q: Can the P ONE MK2 be used as a full-range amplifier?
A: Yes. With a frequency response extending beyond 40 kHz and very low distortion, it is suited to full-range use as well as driving subwoofers.
