Our take on the Pioneer GM-A3602

by Buck Pomerantz
Pioneer

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Plays loud and clear

Many people never think to upgrade their car's audio system, suffering with subpar sound when they listen to music. Pioneer's GM-A3602 2-channel amplifier will greatly improve the sound quality in your vehicle, so you'll look forward to spending time on the road. This punchy little Pioneer amp will power a pair of speakers with 60 watts RMS each, which is a huge jump over the power supplied by your car radio. You'll hear more of the little details in your music, even when you turn your system up to compete with the road noise.

Practical features

You can put this versatile amp into 1-channel mode, switch on the low-pass filter, and run a subwoofer with up to 180 watts RMS, for some rockin' bass. Speaker-level inputs allow you to add the GM-A3602 to a factory radio. This amp's small footprint and reasonable price make it a great choice for almost any vehicle needing a sonic upgrade.

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-A3602 is rated at 60 watts RMS x 2 channels, with a 78 dBA signal to noise ratio.

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

  • Power:
    • 2Ω: 90 watts x 2 channels (14.4 volts, 1 kHz, no more than 1% THD+N)
    • Bridged: 180 watts x 1 channel (into 4Ω, 14.4 volts, 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 (300mV-6.5V line level, 3V-26V speaker level).

Gain Control Caution: If the gain control level is set too high, Pioneer's Gain Control Caution feature will automatically reduce the amplifier's output until the headunit volume is decreased to acceptable levels. This added layer of protection helps prevent damage to the amplifier and the connected speakers due to improper gain control adjustments.

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. 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 a single 25-amp ATO blade fuse.

2 questions already asked

I have a pair of JBL GTO638 speakers rated at 60W at 2Ohms each. Can I use this amp? It's stated at 90W at 2 Ohms. [ Desmond  May 29, 2014 ]
4 answers
  • It will work nicely. [ RICH   May 30, 2014 ]
  • Yes Plenty of power in a small package. Very happy with this amp! [ DAVID A   May 29, 2014 ]
  • I do not see why not because you can turn down the amp. I am running the amp 6x9 Rockform Fosgate that are rated at 150 watts (peak), 2 ohms. I am not using near the power that the amp could put out. I drive a Ram 1500, sounds good enough to wear I need to add some dynamat to the rear doors. I hope this helps. [ Christopher   May 29, 2014 ]
  • You should be able to use this amp, however, I would want an amp that has a equal or a little greater wattage then my speakers. 2 Speakers @ 60W=120Watts and this amp is at 90 Watts. I would recommend an amp that is equal or greater than 120 Watts. [ BOBBY   May 29, 2014 ]
I have a pioneer 12 inch sub, what size amp do I need? [ Cade Barnes  Mar 07, 2014 ]
1 answer
  • Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Jeff Staff  Mar 07, 2014 ]
