Plays loud and clear
Why put an amplifier in your car? Pioneer's GM-A5702 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 Pioneer will power a pair of speakers with 150 watts RMS each, which is a gigantic jump over the power supplied by your car radio alone. You'll hear a lot more of the little details in your music, especially when you turn your system up to overcome road noise.
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 480 watts RMS, perfect for some rockin' bass. A bass boost adds extra kick, if you want it. Speaker-level inputs allow you to add the GM-A5702 to a factory radio that doesn't have preamp outputs. If your vehicle needs a sonic upgrade, this amp's performance features and reasonable price make it a great choice.

Ran 4 gauge to it, Powers my 2 10"fosgate dvc @4 ohms bridged better than i anticipated, it cranks! Amp hardly gets warm to the touch. Great amp for the price.

Guest from Lexington, KY on 5/9/2019
This is a very good Amplifier... Most of the negative to mediocre comments stem from being connected improperly. In bridge mode this amp is only 4 ohm stable.... Make sure you speaker configuration supports the amplifier specification. Load limit 4 ohm bridged and 2 ohm per channel.

A super-duper amp that doesn't get to loud!
Barry from Woodbridge, VA on 11/25/2018
If you're looking for an amp that has the physical appearance of a 1,000-watt RMS amp, but doesn't get too loud, this is amp for you! If you're looking for an amp that can power say two subwoofers, and you're good with 150 watts for each of them, this is the amp for you! On a good note this amplifier does amplify sound, but not that much. Also, when it's cold outside, this amp gets really hot within about two minutes of use to keep you warm on cold days; that's good right? ...Read the label. "1000W" does not equal 1,000 watts.
Pros: Amplifier does amplify sound.
Cons: "1000W" does not equal 1,000 watts.

Great amp for a sub
Rich from Ellicott City, MD on 10/12/2018
Light weight, easy install, clear instructions, I have this powering a single 12" sub in a sealed enclosure, a separate Pioneer amp powering the components and a Pioneer Head unit, this replaces the factory Mach 460 system, this amp is perfect for this setup, thundering bass And I listen to all types of music, plenty of power for my sub.
Pros: Easy install, light weight, clear instructions, great power
Cons: None yet

Doesn't get hot
Jon from Tyrone, PA on 1/24/2018
This amp is powerful. As with just about all amps, you can't run it at 1 ohm bridged. So if your subwoofer is a Kicker 43CWR102, this is a dual 2 ohm sub. Which means you are running at 1 ohm. Its no wonder it gets hot. Incorrect usage like this will void the warranty. When using this amplifier in bridged mode, ensure you have a 4 ohm load and it will be fine.
Pros: Powerful
Cons: No high pass x-over

Don't push this Hard
Steve from Sheridan, WY on 9/3/2017
Hooked this up to a Kicker 43cwr102 10" sub(400 watt rms) and ran the amp in mono at 480 watts rms and after about 5 minutes the amp was almost too hot to touch...would not recommend for any subs or systems that is going to push this amp...
Pros: affordability
Cons: gets extremely hot when pushed hard

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-A5702 is rated at 150 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: 240 watts x 2 channels (14.4 volts, 1 kHz, no more than 1% THD+N)
- Bridged: 480 watts x 1 channel (into 4Ω, 14.4 volts, 1 kHz, no more than 1% THD+N)
- Signal to Noise Ratio: 96 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 variable between 40Hz and 500Hz, and the slope is 12dB/octave. You can adjust the crossover frequency via the provided rotary control.
Bass Boost: The GM-A5702 has a selectable bass boost at 50 Hz. You can set the boost at 0dB, +6dB, or +12dB.
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 60 amps, 8 AWG power and ground wire is recommended. A 60A 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 two 30-amp ATO blade fuses.
