The Autotek Super Sport AT-Series Amplifiers are designed to provide high-level performance and feature a range of models suitable for various audio setups. These amplifiers are engineered to deliver clean, powerful sound with minimal distortion and are equipped with features that allow for precise control over the audio output.
Function Description
The AT-Series amplifiers are designed to amplify audio signals from a head unit or other audio source to power car speakers. They offer a variety of configurations, including 2-channel, 4-channel, and 1-channel (mono) applications, catering to different system requirements. All models feature variable crossovers (High Pass, Low Pass, and selectable Mono/Stereo switch) to optimize sound delivery to specific speakers (e.g., tweeters, mid-range, subwoofers). High-level inputs are included for compatibility with factory head units that lack RCA outputs.
Important Technical Specifications

Both models have a frequency response of 30Hz-1.2kHz, a damping factor of >200, and a signal-to-noise ratio of >95dB. THD & N is <0.05%. Input impedance is 47kΩ. Crossover options include a variable HPF (30Hz-1.2kHz) and LPF (30Hz-250Hz). Bass Boost is 0-12dB.
- AT950 / AT1200 (4-Channel Amplifiers): These amplifiers are suitable for full-range stereo or 3-channel full-range applications. The AT950 offers 120W x 4 at 4 Ohms and 240W x 4 at 2 Ohms, with bridged outputs of 480W x 2 at 4 Ohms. The AT1200 provides 150W x 4 at 4 Ohms and 300W x 4 at 2 Ohms, with bridged outputs of 600W x 2 at 4 Ohms. Both models share a frequency response of 30Hz-1.2kHz, a damping factor of >180, and a signal-to-noise ratio of >90dB. THD & N is <0.05%. Input impedance is 47kΩ. Crossover options include variable HPF (30Hz-1.2kHz) and LPF (30Hz-250Hz). Bass Boost is 0-12dB.
- AT2000.1 / AT3000.1 (1-Channel Mono Amplifiers): These models are designed specifically for subwoofer applications. The AT2000.1 delivers 500W x 1 at 4 Ohms, 1000W x 1 at 2 Ohms, and 2000W x 1 at 1 Ohm. The AT3000.1 provides 750W x 1 at 4 Ohms, 1500W x 1 at 2 Ohms, and 3000W x 1 at 1 Ohm. Both mono amplifiers have a frequency response of 15Hz-300Hz, a damping factor of >200, and a signal-to-noise ratio of >95dB. THD & N is <0.10%. Input impedance is 47kΩ. Crossover options include a variable LPF (30Hz-250Hz) and a subsonic filter (15Hz-55Hz). Bass Boost is 0-12dB.
- Protection Features: All models include PowerProtect circuitry to safeguard against short circuits, thermal overload, and DC offset.
- Dimensions: The amplifiers vary in size, with the AT1000 measuring 9.85 x 2.17 x 12.6 inches and the AT3000.1 measuring 9.85 x 2.17 x 17.72 inches.
Usage Features
- General Installation: The manual emphasizes mounting the amplifier to a board of MDF or other solid material to minimize noise and improve cooling. Proper wiring with adequate gauge power and ground cables is crucial for optimal performance. The use of RCA cables with good quality shielding is recommended to prevent noise.
- Crossover Controls: Each amplifier features adjustable crossover networks.
- AT1000/AT1500: Includes a MONO/STEREO switch, HIGH PASS (30Hz-1.2kHz), LOW PASS (30Hz-250Hz), and BASS EQ (0 to +12dB at 45Hz).
- AT950/AT1200: Features a 2/4 CHANNEL switch, HIGH PASS (30Hz-1.2kHz), LOW PASS (30Hz-250Hz), and BASS EQ (0 to +12dB at 45Hz).
- AT2000.1/AT3000.1: Includes a REMOTE control input, PROTECT/POWER indicators, BASS EQ (0 to +12dB at 45Hz), PHASE (0 to 180 degrees), LPF (30Hz-250Hz), and SUBSONIC filter (15Hz-55Hz).
- Input Sensitivity: The amplifiers have adjustable input level controls to match the output of the head unit, ranging from 0.2V to 6V for RCA inputs and 0.5V to 10V for high-level inputs.
- Remote Bass Control: The mono amplifiers (AT2000.1/AT3000.1) include a remote bass control for convenient adjustment of subwoofer output.
- Bi-Amplified Systems: The AT1000/AT1500 models can be used in bi-amplified systems, allowing separate amplification for high and low frequencies.
- Multi-Channel Configurations: The AT950/AT1200 models support 4-channel full-range or 2 or 3-channel full-range setups, offering flexibility for various speaker arrangements.
- Minimum Final Loudspeaker Impedance: The 2-channel and 4-channel amplifiers support 2-Ohm stereo and 4-Ohm bridged loads. The mono amplifiers support 1-Ohm loads. It is critical not to exceed the minimum impedance to prevent damage.
Maintenance Features
- Troubleshooting: The manual provides a comprehensive troubleshooting section to address common issues such as no power, no sound, distorted sound, excessive heat, and noise problems.
- No Power: Check battery voltage, ground connections, and fuses. Ensure the remote turn-on wire is connected and receiving +12 volts.
- No Sound: Verify RCA cable connections, speaker wires, and crossover settings. Check for blown fuses.
- Distorted Sound: Adjust input level controls, check speaker impedance, and ensure proper crossover settings.
- Overheating: Ensure adequate ventilation around the amplifier. Check speaker impedance and input levels.
- Noise Problems: Identify and eliminate sources of noise, such as poor grounding, unshielded RCA cables, or engine noise. Use high-quality RCA cables and ensure proper wiring.
