Practical features

You can also put this versatile amp into single-channel mode, switch on the low-pass filter for clarity, and run a subwoofer with up to 480 watts RMS, perfect for some rockin' bass. A bass boost adds extra kick, if you want it. Speaker-level inputs allow you to add the GM-A5702 to a factory radio that doesn't have preamp outputs. If your vehicle needs a sonic upgrade, this amp's performance features and reasonable price make it a great choice.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods 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 power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare amplifiers on an equal basis. Using CEA-2006 criteria, the Pioneer GM-A5702 is rated at 150 watts RMS x 2 channels, with a 75 dBA signal to noise ratio.

Specifications: The manual also lists these non CEA-2006 compliant specifications:

  • Power:
    • 2Ω: 240 watts x 2 channels (14.4 volts, 1 kHz, no more than 1% THD+N)
    • Bridged: 480 watts x 1 channel (into 4Ω, 14.4 volts, 1 kHz, no more than 1% THD+N)
  • Signal to Noise Ratio: 96 dB (at rated power)

Gain Control: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the input gain is adjustable (0.3V-6.5V line level, 3V-26V speaker level).

LPF: A two position switch turns the low pass filter (LPF) on/off. The crossover point is variable between 40Hz and 500Hz, and the slope is 12dB/octave. You can adjust the crossover frequency via the provided rotary control.

Bass Boost: The GM-A5702 has a selectable bass boost at 50 Hz. You can set the boost at 0dB, +6dB, or +12dB.

Power Connections: The power and ground connections are 0.54" wide screw terminals, the remote turn-on screw terminal is 0.325" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. With a total fuse rating of 60 amps, 8 AWG power and ground wire is recommended. A 60A fuse should be placed on the power wire within 18" of the battery. Spade connectors are recommended for the power, ground, and remote wires.

Speaker Connections: The speaker screw terminals are 0.325" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. Spade connectors are recommended for the speaker wires.

RCA Input: The amplifier features one pair of stereo RCA line level inputs (left/right).

Speaker Input: The included speaker level input harness allows you to connect your OEM radio (or aftermarket radio that does not have the typical RCA-type outputs) without having to buy an adapter.

Auto Power On: When using the speaker level input, a circuit senses the input signal and turns the amp on automatically. This feature makes it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs.

Fuse: The amp is protected by two 30-amp ATO blade fuses.

Q
Im a little confused what does the speaker input plug in do, I thought you just wire the speakers to the amp?
[ Atrain  Aug 16, 2020 ]
1 answer
A
The input comes from your head unit to the amp then the speaker output from the amp to the speakers. Think of it like this, the music comes from the head unit at a lower power level, travels through the amp to the speakers at a higher power level, the amp does not produce music, just makes it louder.

What is the Peak Power?

RMS power is what you need to know. Peak power is a selling gimmick.

Thanks for your question. For information on selecting a compatible amp/sub combo I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine any differences between the amp models and help you make the best choice for your system.

Q
If this amp is rated at 480rms x1 or 150rms x2, then why does it have 1000watts stamped on the front of it in huge red letters???
[ Nick  Feb 07, 2017 ]
1 answer
A
Thats the total peak power in watts for all of the channels combined, I have this amp and I love it, I use it to push two kicker 6x9s with 150w each and it's insanely loud. A lot of companies put that big peak number on their products to lure you in but don't get me wrong it's still amazing
[ Daniel  Feb 07, 2017 ]
Q
Could I safely bridge this amp to push a single sub at 2 ohms?
[ Zachariah  Dec 28, 2016 ]

A
YES IF SPACE IS AN ISSUE 2 10 INCH BETTER PUNCH THIS SIZE AMP I WOULD USE FOR DOOR SPEAKERS FRONT OR BACK MAYBE A LITTLE BIGER FOR KICKER SUB
[ SHAWN  Nov 05, 2020 ]
A
I'm afraid not--the Pioneer GM-A5702 is only stable down to 4-ohm in bridged mode. You may want to consider a mono amplifier instead. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat.
[ Larry  Jan 05, 2017 ]  Staff
Q
Will this power a sub with 50-400 watts RMS and 2 speakers with 5-75 watts RMS?
