Ground Zero GZIA 2.135 2-Channel Class A/B Amplifier
The Ground Zero GZIA 2.135 is a high-quality 2-channel Class A/B amplifier to enhance your car audio system. It delivers robust power output and ensures clear and dynamic sound reproduction. Its compact design and advanced features make it versatile for various installations.
High-Quality Class A/B Amplification
The GZIA 2.135 utilizes Class A/B technology, balancing efficiency and audio fidelity. This design ensures minimal distortion and a high signal-to-noise ratio, producing clear and accurate sound reproduction. The amplifier delivers 85 watts RMS per channel at 4 ohms and 135 watts RMS per channel at 2 ohms, accommodating various speaker configurations. Its stable power supply maintains consistent performance across different loads.
Variable Active Crossover and Bass Boost
Equipped with a variable active crossover, the GZIA 2.135 allows precise control over frequency distribution to your speakers. The high-pass filter ranges from 40 Hz to 3,000 Hz, and the low-pass filter ranges from 30 Hz to 250 Hz, enabling customization to match your system's needs. An adjustable bass boost function further enhances low-frequency response, providing up to 12 dB of boost for deeper bass. These features offer flexibility in tailoring your audio experience.
High-Level Input with Auto-On Function
The amplifier includes a high-level input with an auto-on function, facilitating seamless integration with factory-installed head units. This feature detects incoming audio signals and powers on the amplifier automatically, eliminating the need for a separate remote turn-on wire. It simplifies installation and ensures compatibility with a wide range of audio sources. The auto-on function enhances user convenience and system versatility.
Durable Design with Efficient Cooling
Featuring a black anodized heatsink with Ground Zero lettering, the GZIA 2.135 combines durability with aesthetic appeal. The robust construction ensures longevity, while the efficient cooling system prevents overheating during extended use. Large terminals accommodate heavy-gauge wiring, ensuring secure and efficient power connections.

| General Specifications | |
Frequency Response Frequency Response in a car amplifier refers to the range of audio frequencies it can amplify, typically measured in Hz. For example, a response of 20Hz to 20kHz indicates the amp can handle deep bass to high treble, covering the full audible spectrum.
|
|
S/N Ratio S/N Ratio (Signal-to-Noise Ratio): A measure of an amplifier's ability to amplify audio signals relative to background noise. A higher S/N ratio indicates clearer sound, as more of the output is dedicated to the signal rather than noise.
|
|
THD+N @ Rated Power THD+N (Total Harmonic Distortion plus Noise): A measurement of the total distortion and noise introduced by an amplifier. Lower values indicate cleaner audio reproduction, as less distortion and noise affect the output signal.
|
|
Input Voltage Range Input Voltage Range: The range of voltage levels an amplifier can accept from the audio source. It determines compatibility with various head units or signal processors, ensuring optimal signal strength without distortion or clipping.
|
|
Low Pass Filter Low Pass Filter: A feature that allows only frequencies below a specified cutoff point to pass through to the subwoofer, blocking higher frequencies to ensure cleaner bass output.
|
|
Crossover Slope Crossover Slope: The rate at which frequencies are attenuated beyond the crossover point, measured in dB per octave. Steeper slopes (e.g., 24 dB/octave) provide more precise separation between frequency ranges, improving sound clarity.
|
|
Fuse Rating Fuse Rating: The maximum current an amplifier can handle before its fuse blows, protecting the unit from damage. It indicates the amp’s power capacity and helps ensure safe operation within the electrical system.
