Product Description

Features & Specifications




Pioneer GM-ME500X1 Mono Marine Amplifier

Pioneer’s GM-ME500X1 is a Marine grade Class-D digital amplifier specifically designed for the marine environment, including features such as special painting, protective covers for the side panels and RCA terminal covers.

To prevent circuit shutdown, Pioneer’s GM-ME500X1 digital amplifier circuit includes a “Protection Control System” senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 ? connection. This design enhances the flexibility to connect multiple subwoofers to a system.

For extra flexibility, easy installation is guaranteed thank to “Automatic Signal Sensing and Turn-On”, which automatically detects an input signal and turns the amplifier on and off when connected via the speaker line input.

Variable Low Pass Filter (LPF) means you can adjust the audio frequency more according to the subwoofer characteristics and personal listening preferences. The GM-ME500X1 also includes a wired Bass Boost Remote Control.

The GM-ME500X1 has a sleek design thanks to its white cosmetics and hairline top plate enhancing the high quality sense of design and a total of 1600W.

Big bass in the sea

It takes a lot of amplifier power for your bass notes to be heard clearly over the sounds of the waves, wind, and engine noise. Pioneer’s ME-Series GM-ME500X1 mono marine subwoofer amplifier can put out up to 800 watts RMS, enough for everyone in and around your boat to feel the beat.

Pioneer’s ME-Series awesomeness

This amplifier’s output power matches up nicely with Pioneer’s ME-Series TS-ME100WS and TS-ME100WC marine subwoofers, allowing you to build up a large system by adding one sub at a time. When running one sub, the amp puts out 300 watts RMS, exactly the power rating of the sub. With two subs, the amp sends out 500 watts RMS total, 250 watts to each sub. With three of them, it delivers about 700 watts RMS, about 233 watts per sub. And with four, it produces a whopping 800 watts RMS, 200 per sub. Not bad for one little amp.

More info

The GM-ME500X1 features a low-pass and a subsonic filter to tune the bass tones to match your subs and make them sound good. Conformal coated circuit boards and rubber connection/control covers keep water and dirt away from sensitive areas.

CTA-2006 Compliant: CTA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier’s RMS power output and signal-to-noise ratio. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CTA-2006 standards allow consumers to compare amplifiers and receivers under the same conditions (apples to apples).

CTA-2006 Specifications:

  • Power Output: 300 watts RMS x 1
  • Signal to Noise Ratio: 75 dBA

Other Specifications:

  • Power Output:
    • 2″: 500 watts RMS x 1 (14.4 volts, 100 Hz, ?1.0% THD)
    • 1″: 800 watts RMS x 1 (14.4 volts, 100 Hz, ?1.0% THD)
  • Signal to Noise Ratio: 100 dB (at rated power output)
  • Frequency Response: 10 Hz – 240 Hz (+0/-3 dB)

Speaker Level Input: The RCA input jacks can be used for preamp level or speaker level input signals. If connecting the source unit’s speaker wire to the input jacks, use the included Speaker-to-RCA adapter. When using a speaker level input signal, it may not be necessary to connect a remote turn-on lead because of the amplifier’s signal sensing function.

Pre-Output: An additional pair of RCA jacks provides a line level output for sending a signal to another amplifier. The output matches the signal at input, and is not affected by the amplifier’s crossover.


  • Gain: rotary control; adjustment range depends on the input type; automatically selected between 200mV to 6.5V (preamp level) and 800mV to 16V (speaker level)
  • Frequency: rotary control for crossover point; variable from 40 Hz to 240 Hz
  • Subsonic Filter: 2-position switch; on/off; 30 Hz crossover point, 24 dB/octave slope


  • RCA Inputs: one pair of stereo RCA inputs; used for both speaker level and preamp level signals
  • RCA Outputs: one pair of stereo RCA outputs; outputs the signal at the input
  • Speaker Outputs: two pair of set-screw terminals; internally shorted together, making is easy to connect two subwoofers in parallel; the terminals will accept up to 8-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screws
  • Power: set-screw terminal; accepts up to 4-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screw
  • Ground: set-screw terminal; accepts up to 4-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screw
  • Remote Turn-on: set-screw terminal; accepts up to 8-gauge wire; the included 3mm Allen wrench is used to tighten/loosen the set screw
  • Fuses: two 40-amp ATO fuses are mounted on the side of the amp
