Powerful 4-Channel Amplification
The GM-A6704 delivers 60W RMS per channel to power your front and rear speakers with clear and detailed sound. When bridged, the amplifier can provide up to 190W RMS to drive a subwoofer or a pair of high-performance speakers.Flexible System Configuration
This amplifier allows multiple installation setups. You can power four speakers, run front speakers while bridging rear channels for a subwoofer, or use 2-channel mode to send higher power to component speakers or subwoofers.High-Quality Power Supply
The amplifier features an advanced internal power supply designed to maintain stable power delivery even during demanding bass-heavy playback. This improves sound dynamics and reduces distortion.Automatic Signal Sensing
When connected to factory audio systems without RCA outputs, the amplifier can automatically power on when it detects an audio signal through the speaker-level inputs. This allows easy integration with OEM head units.Adjustable Bass Boost
The built-in bass boost control lets you enhance low frequencies with adjustable levels between 0 and 12 dB at 50 Hz, allowing you to tailor the bass response to your music preferences.Advanced Crossover Filters
Channel A includes a variable high-pass filter from 40 Hz to 500 Hz or a fixed low-pass filter at 80 Hz for detailed tuning. Channel B features selectable high-pass or low-pass filtering at 80 Hz, helping optimise sound for speakers or subwoofers.Durable Amplifier Design
The amplifier uses a solid chassis and effective heat dissipation to maintain stable performance during extended listening sessions, ensuring long-term reliability.Specifications
