Key Features of the Pioneer GM-E7004 4 Channel Amplifier
1. 4-Channel Bridgeable Design
The GM-E7004’s flexible bridgeable architecture allows you to run it in 4-channel, 3-channel, or 2-channel modes. This adaptability lets you power multiple speakers or pair channels to drive subwoofers, depending on your system setup.
2. Maximum Power Output – 1000W
Experience intense, high-output sound with up to 1000 watts max power. This amplifier delivers ample headroom for clean, undistorted sound reproduction even at higher volumes.
3. Built-In Bass Boost (0-12dB at 50Hz)
Customize your low-frequency response with the variable bass boost control. Adjust it between 0 and +12 dB at 50 Hz to enhance your subwoofer’s punch and depth for a truly powerful bass performance.
4. High- and Low-Level Inputs
Compatible with both RCA (low-level) and speaker line (high-level) inputs, this amplifier can integrate with factory or aftermarket head units—making installation simple and versatile.
5. Automatic Signal Sensing and Turn-On
When using high-level inputs, the amplifier automatically detects a signal and powers on—eliminating the need for a separate remote turn-on wire in certain setups.
