Why put an amplifier in your car? Pioneer's GM-A3702 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 little Pioneer will power a pair of speakers with 60 watts RMS each, which is a gigantic jump over the power supplied by your car radio alone. You'll hear 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 190 watts RMS, perfect for a modest system. Speaker-level inputs allow you to add the GM-A3702 to a factory radio that doesn't have preamp outputs. If your vehicle needs a sonic upgrade, this amp's small footprint 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-A3702 is rated at 60 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: 95 watts x 2 channels (14.4 volts, 1 kHz, no more than 1% THD+N)
- Bridged: 190 watts x 1 channel (into 4Ω, 14.4 volts, 1 kHz, no more than 1% THD+N)
- Signal to Noise Ratio: 95 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 fixed at 80 Hz and the slope is 12dB/octave.
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 25 amps, 10 AWG power and ground wire is recommended. A 25A 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 one 25-amp ATO blade fuse.
