6. Setup and Installation
Before installation, plan the placement of the amplifier. Choose a location that provides good ventilation, is protected from moisture, and is easily accessible for wiring and adjustments.
6.1. Wiring Connections
Refer to the diagram below for proper wiring. Ensure all connections are secure and insulated to prevent short circuits.
- Power Input: Connect the positive (+) terminal to the vehicle's battery via an 11 AWG cable and a 20A fuse/circuit breaker. Connect the negative (-) terminal to a solid chassis ground point using an 11 AWG cable. The Remote (REM) terminal should be connected to the remote output of your head unit using an 18 AWG cable.
- Speaker Output: Connect your speakers to the CH1, CH2, CH3, and CH4 terminals. For stereo operation, each channel supports 2 Ohms. For bridged operation, combine channels (CH1+CH2 and CH3+CH4) to achieve 200 Watts RMS per bridged pair at 4 Ohms. Use 15 AWG cables for speaker outputs.
- RCA Input: Connect the RCA cables from your head unit's pre-out to the amplifier's RCA input terminals (CH1/CH2 and CH3/CH4).

7. Operating Instructions
The TS 400x4 amplifier features controls for optimizing audio output:
- Level (Gain) Control: Adjust this knob to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until you achieve clear, undistorted sound at your desired volume.
- Crossover Switch: This switch allows you to select the frequency range for the output.
- LPF (Low Pass Filter): Allows only low frequencies to pass through, ideal for subwoofers.
- HPF (High Pass Filter): Allows only high frequencies to pass through, ideal for tweeters or full-range speakers where bass is handled by a separate subwoofer.
- FULL: Allows the full frequency range to pass through, suitable for full-range speakers.
- LED Indicator: The amplifier features an LED indicator that shows its operational status (e.g., power on, protection mode). Refer to the full user manual for specific LED codes.
