Plays loud and clear
Why put an amplifier in your car? Pioneer's GM-A5702 2-channel amplifier will greatly improve the sound quality in your vehicle, so you'll find yourself looking forward to your time on the road. This punchy Pioneer will power a pair of speakers with 150 watts RMS each, which is a gigantic jump over the power supplied by your car radio alone. You'll hear a lot more of the little details in your music, especially when you turn your system up to overcome road noise.
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.

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:
- 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.
