- Key Specs
- Amplifier Class: Not Applicable (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 0
- Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)

An amplifier shouldn’t take up too much space, especially in your car. The GM-D8704 might just be what you’re looking for. It combines a 1-Ohm stable circuit, installation flexibility, and superior high-power output.
- Big power, small size: Pioneer’s extra-efficient Class-D amplifiers mark a dramatic improvement in power output capability yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.
- Improved circuit design: To prevent circuit shutdown, Pioneer's digital amplifier circuit protection control system senses its internal temperature and automatically moderates input level. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 ff connection.
- Variable low-pass and high-pass filter: For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D8704 LPF is adjustable from 40 Hz to 500 Hz.

Product Manuals
A: The Pioneer GM-D8704 / GM-DX874 will work great with these speakers wired at 4 ohms with 2 on the "A" channel and two on the "B" channel. This amp will make these speakers sound loud and clear and be super reliable over time. You're aware of the power rating on the speakers, so when you install the amp, you can roll the gain for both channels back a little to give you a safety buffer at high volume, or you can push the gain up a little and simply be aware that at the receiver's highest volume, you'll be flirting with danger of damaging the speakers. Be aware and play it smart and both will work great for a long time.
