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.

Product Highlights:

  • 2-channel car amplifier
  • 60 watts RMS x 2 at 4 ohms (90 watts RMS x 2 at 2 ohms)
  • 180 watts RMS x 1 in bridged mode (4-ohm stable in bridged mode)
  • CEA-2006 compliant
  • selectable low-pass filter (80 Hz, 12 dB per octave)
  • Class AB amp technology, MOSFET power supply
  • preamp and speaker-level inputs
  • fuse rating: 25A x 1
  • 8-gauge power and ground leads recommended — wiring and hardware not included with amplifier
  • 9-1/2"W x 2-3/8"H x 7-1/8"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Very happy with the amp. No need to run a line from amp to head unit for switch on as long as you use the speaker input along with the provided connection harness.

Pros: speaker input with connection harness

Cons: none

Works great! Not a good idea for a sub because it is not powerful enough.

Just enough low end

I use this amplifier to power a 10 inch alpine subwoofer and the bass hits harder then I thought a 400w amp would hit.

Pros: Easy setup looks great

Cons: None

Good for basic install

Written By Wrench, Colorado on Tuesday, December 09, 2014

Crutchfield Customer Review (What's this?)

This amp is a good little overall amp if used for a stock system with the right sub. I used rockford slim in my 09 f-150 and the two sound great but I used a Pioneer 10" in my 13 mustang and with the shaker 500 system all ready in it I did not see much of difference in lows and does not hit as hard as the rockford slim. If purchasing this amp I would recommend a rockford sub and not a pioneer to go with it.

Pros: Price good and easy install

Cons: Not very hard hitting and seems to like other brand subs better then sister componets.

I have this 2 channel amp hooked up in my 96 Chevy astro for my front speakers an head unit. It makes it all sound amazing. Best amp I have got. But I do suggest if you are thinking about an amp stick with pioneer speakers an head unit. Them all together sounds amazing.

I am super pleased with this amp, The install was painless and it drives the single 10" I am running flawlessly, it doesnt get overly warm which is nice given the fairly tight install space.

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.
