Practical features

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.

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-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:

  • Power:
    • 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.

Can this amp handle a 12 inch woofer?

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.

No. Pick a side and wire it to your wire harness accordingly

Will run 6x9s no problem
[ TYLER  Apr 21, 2020 ]  Staff
A
That is exactly what I am using it for, Rockford-Fosgate 6x9's.
[ ROBERT  Apr 21, 2020 ]  Staff
A
Yes you can run a pair of 6x9s off it. Just make sure you keep the ohm load above 2 ohms per chamnel.

Im no professional but in my opinion should work great for those speakers.
[ JASON  Dec 27, 2019 ]  Staff
A
Oh yeah. Nice unit.
[ Brad  Dec 27, 2019 ]  Staff
A
Yes, but with those speakers you could run a higher power amp that would better match the speakers characteristics.

Q
Will this amp work with speakers that only hold 50 watts rms? Or will it be to much?
[ Mike  Dec 22, 2019 ]
3 answers
A
I'm using a couple of 20 watt speakers connected to each channel and they work fine. Just be careful you don't overdrive them for extended periods. You'll know it too much power when you start suffering hearing loss. Good Luck, if have any further questions, I'm happy to help! Jeff
[ Jeff  Jan 08, 2020 ]  Staff
A
The amp will push those 50 rms speakers really hard, I have it connected to a 400 peak sub and it pushes it hard, so to answer your question yes, it will push them , just be muscular with the volume

Q
Will this provide sufficient power for a set of Infinity Pappas component set 60.11?
[ Eminemgsr  Mar 31, 2018 ]
3 answers
A
Definitely, Infinity's are very efficient (93 dB sensitivity) and the Pioneer amp is a good affordable power solution.
[ Aaron  Apr 09, 2018 ]  Staff
A
I returned this amp. I found the power to be raw and unrefined. It is affordable but I think there are better products out there for the money.
[ NATHANIEL  Apr 08, 2018 ]  Staff
A
Yes. This amp is 60 watts RMS at 4 ohm and 95 watts at 2 ohms. The Kappas are 90 watts RMS at 2 ohms I'm pretty sure.
[ Caleb  Apr 07, 2018 ]  Staff
Q
Will this 2 channel amp power 4 aftermarket door speakers (Pioneer Model: TS-G1645R) rated at 4 ohms?
[ Nickt  Sep 09, 2017 ]
1 answer
A
Yes it should be able to at 47.5 watts per speaker, but you won't be able to use fader controls like you can with a 4 channel amp and there will be more distortion pushing what it will see as a 2 ohm setup if you wire in parallel.
[ Jeremy  Sep 09, 2017 ]  Staff
Q
Should i add a high pass filter to this amp so bass would only go to my subs running on a different amp?
[ Isaac  Jun 29, 2017 ]

Q
Would this amp work for a component speaker system or is it desined for subs only?
[ Boneskull  Apr 02, 2017 ]
2 answers
A
This will work on component or Sub. It is actually probably meant more for components. If connecting to a sub you will want to bridge this amp to get the most out of it. I have this connected to a Memphis 8" sub bridged, cranked up and still wish it had just a little more juice.
[ Ivan  Apr 04, 2017 ]  Staff
A
Yes. It can be used to power 2 component speakers. Make sure you check the power rating of the speakers you wish to use to be sure they are compatible with the power rating of the amp.
[ Curt  Apr 04, 2017 ]  Staff
Q
In bridged mode it says 190 watts x1, 4 ohm stable. I am curious if that means it pushes 190 to a single 4 ohm speaker (sub)? Also, if you are wanting to use the auto power on speaker level feature, do you need rca adapters or anything like that to plug in to it?
[ Rocky  Mar 25, 2017 ]
1 answer
A
You can bridged the 2-channels on this amp down to a single channel in order to drive a single speaker or subwoofer. And 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. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. Hope that helps!
