Description

Description

Combines attractive design and high power, offering absolute installation freedom and zero distortion. This 4-channel amplifier allows you to drive multiple speakers and subwoofers, and it can also be bridged to drive a single subwoofer.

Crystal Clear RMS Sound and Detail Enhancement

The Pioneer GM-A6704 amplifier is designed to dramatically improve the audio experience inside your vehicle. It powers the front and rear speakers with clean continuous power of 60 watts RMS per channel, allowing you to hear all the small details of your tracks with absolute clarity. This increased power ensures that the sound remains clear and free of distortion, even when you turn up the system volume to overcome outside road noise.

Bridging Flexibility and Monophonic Operation

The amplifier’s multi-channel architecture offers exceptional flexibility in configuring the audio system. It allows you to drive the front speakers through channels "A" and bridge channels "B" for the independent power supply of a subwoofer. In addition, this versatile amplifier can be set to 2-channel mode, delivering the impressive power of 190 watts RMS per channel to a pair of demanding component speakers or subwoofers.

Adjustable HPF Filter and Factory Connection

The device incorporates an adjustable Variable High Pass Filter (HPF), offering the ability to adjust frequencies from 40 Hz to 500 Hz. This ensures enhanced flexibility for precise frequency separation based on the characteristics of the subwoofer and your personal preferences. At the same time, the Speaker-level inputs allow the amplifier to be easily added even to factory head units that do not have pre-amplified RCA outputs.

    Excellent for its price! Small size, fits easily everywhere, and with proper adjustment and a decent source, it plays very nicely and clearly!

    With proper installation, proper speakers, and proper adjustment, it works just fine. Installed in a VW POLO 6R (under the passenger seat) with 4 Focal IS 165 VW speakers and a Sony XAV-AX1005DB source. Very good sound quality and volume. It's not for competitions, let's have the right expectations, for €120 it's just fine.
