4. Setup and Installation
The CA-AEC01 amplifier is designed for easy integration with ATOTO head units. Its compact size allows it to fit within the dashboard opening, maintaining a clean and tidy car interior. The installation process is streamlined, often not requiring a new power supply wire from the battery due to efficient power management technology.
Installation Steps:
- Step 1: Mount the Amplifier
Tune the car amplifier's EQ settings (Bass, Mid, High) as desired before mounting. Then, mount the amplifier onto the head unit using the provided screws and brackets. - Step 2: Connect Input Cable to Head Unit
Identify the power socket on your head unit. If it is 16PIN, use the 16PIN-20PIN cable. If it is 20PIN, use the 20PIN-20PIN cable. Plug the appropriate cable into the head unit's power socket. - Step 3: Connect Input Cable to Amplifier
Plug the 20PIN side of the cable (from Step 2) into the input socket on the amplifier. - Step 4: Connect Power Cable from Car
Connect the power cable from your car to the amplifier's output socket. Choose either the 20PIN or 16PIN output socket based on your car's power cable configuration.

5. Operating the Amplifier
The ATOTO CA-AEC01 amplifier features built-in EQ gain adjustment knobs for fine-tuning your audio output. These controls allow you to customize the sound profile to your preference.
EQ Gain Adjustment:
- Bass: Adjusts low-frequency sounds.
- Mid: Adjusts mid-range frequency sounds.
- High: Adjusts high-frequency sounds.
Each band can be adjusted by ±10dB. It is recommended to set these before final installation, as they may become less accessible once the unit is fully mounted.
