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 Research

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.

Is this a good amp if I have two 12" speakers?

gerald Jun 26, 2016

Yes, it's an awesome amp I have two alpine 90W marine speakers with mine and it sounds great you just can't turn it all the way up your ears can't take it nor can the speakers.

mark Jun 28, 2016

I have it hooked to two 8" subs and sounds great

ryan Jun 27, 2016

Can I bridge this amp to power my Kicker 40CS6934 6x9's? 150 watts RMS

michael Jan 12, 2016

1 answer

Unfortunately this amp is not rated 2-ohm mono operation (as you are describing). Have a quick call or chat with an Advisor. They will be able to help find an amp that will power your speakers and fit your budget.

jeff Jan 15, 2016 (Staff)

I'm using this amp unbridged to power two rear speakers, (sounds awesome). Can I add a sub simply by running wires from the "bridge" terminals? The amp would then be running the two rear coaxles and the sub. I know I'd reduce overall power to each speaker, but is that possible?

asa Sep 25, 2015

I wouldn't do that..you run the risk of destroying the amp.

shane m. Sep 28, 2015

I Don't think it will work, because the amp must be set to low pas filter to push the sub. And the amp must be set to high pas filter to power the rear speakers. Hope this helps....

jose Sep 28, 2015

Hey there . probably gonna buy this amp. However I need to know ; Can i switch off the current crossover on the amp ? How ?

dofly Sep 03, 2015

yes it has a switch and adjustable screws for whatever type of music you listen to

ryan Jun 27, 2016

Yes, it has a switch.

patrick Sep 04, 2015

Can I run four door speakers from this amp? I have a crew cab GMC Sierra and it has two front door and two rear door speakers

creighton Jul 18, 2015

YES, IT IS A 2 CHANNEL AMP HOWEVER, SO YOUR WATTAGE WILL CHANNEL AS YOUR OHMS DO.

patrick Jul 21, 2015

This is a two channel amp (left and right) or you can bridge it together for one speaker (positive on side / negative on other). You could use this for front and back but will lose. My Pioneer deck runs the front speakers and the amp the back in the doors. I hope this helps.

christopher Jul 20, 2015

If I use the speaker level inputs do I need to use a remote wire for the amp or will the amp automatically turn on with the speaker level inputs?

michael Mar 12, 2015

You need a remote wire from your head unit. The head unit will tell the amp what to do

dale Mar 14, 2015

I believe you still have to use the remote wire.

sam Mar 13, 2015

Run the power, ground and remote as you would with rca cables. Remember the remote wire is what switches the amp on and off. Then tap in to the rear speakers to plug in the high input. I hope this helps

jose Mar 13, 2015

Still need amp rem turn on wire

kelvin Mar 13, 2015

Amp will automatically power on when using speaker-level inputs.

taylor Mar 13, 2015

hello everyone, is it necessairy to use to remote power on cable. Doesn't it start when you use the high level inputs? thank you

bart de munck Feb 16, 2015

2 answers

what's up player? If you have one amp then the high input harness is sufficient you don't need the remote wire. if you have two(2) amps then one amp will need the remote wire and the other amp can use the high input harness. then you connect RCA plugs from one amp to the next to transfer sound.

clyde Feb 19, 2015

Yes if the deck allows it.

What 10" woofers would be best for Pioneer GM-A3602?

dale Feb 12, 2015

Thanks for your question. For information on selecting the best subs for your amp 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.

What does AB stand for? And how can it help me with my shopping for an amp

derek c Nov 02, 2014

1 answer

Class AB is a combination of both Class A and Class B amplifiers. In a Class AB amplifier the output transistors power-down a little when not in use, resulting in good sound fidelity and adequate efficiency (often 50%). Most full-range amplifiers use Class AB technology. You can find out more about amplifier types in our Amplifier FAQ here: http://www.crutchfield.com/learn/learningcenter/car/amplifiers_faq.html?showAll=N#16

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.

It will work nicely.

richard j 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?
