* 480 Watts Max Power
* Variable LPF (low pass filter) & HPF (high pass filter) for Greater Audio System Flexibility
* Speaker Level Inputs
From dramatic distinction to dramatic design, Pioneer's new GM-Series amplifiers are thrillers in every sense, pushing the limits of flexibility & functionality.
The 4-channel GM-A4604 delivers a 480 watts max in a compact design - plenty of juice to power your speakers.
It's also got built-in low-pass/high-pass crossovers, speaker level inputs for easy connection to an OEM headunit & oversized power terminals.
CEA2006 * Power Output: 40 Watts RMS x 4 Channels (4 ohms AT 1% THD+N)
* Signal-to-Noise Ratio: 94 dBA (Reference: 1 Watt into 4 ohms)
Pioneer is constantly finding ways to make amplifier technology better.
Our new & improved GM-Series prove how you can add cutting edge technology & more power to your system without breaking the bank.
Like all Pioneer products, these amps are fully tested to ensure that each is designed & built for performance.
Having more power isn't just about LOUD.
It's also about CLEAN, getting the most out of your speakers & your music.
Constant road noise makes it hard for the music to be heard clearly.
But w/480 watts max.
power, you'll get to hear all the words & all the notes.
Variable LPF (low-pass filter) & HPF (high-pass filter) allow for adjustable frequency between 40 Hz to 500 Hz & greater car audio system flexibility according to subwoofer characteristics & personal listening preferences.
The GM-A4604 has a variable LPF/HPF on Ch.
B & fixed LPF/HPF on Ch.
To suppress power supply loss, GM-Series amplifiers incorporate a large toroidal transformer & are driven using a high-speed switching MOSFET.
This stabilization of power supply maintains stable playback of all types of music.
