System Planning
Proper system planning is crucial for maximizing amplifier performance and ensuring system reliability. Consult your authorized dealer for expert assistance with system design and installation.
Speaker Requirements
Each amplifier channel can drive 4Ω speaker loads in stereo mode. When bridged, the recommended minimum load impedance is 1Ω for subwoofers and 4Ω for full-range operation. Operating with lower impedances may cause overheating and temporary shutdown due to thermal protection. While this may not cause immediate damage, it can reduce the amplifier's lifespan.
Most car audio speakers are 4Ω. Connecting two 4Ω speakers in parallel results in a 2Ω load. Some subwoofers have a dual 4Ω voice coil design; connecting these in parallel results in a 2Ω nominal impedance, which is not recommended for bridged channels.
Wiring Configurations:
- Series wiring: Connect speakers in series to increase impedance. Example: two 8Ω speakers in series result in a 16Ω load.
- Parallel wiring: Connect speakers in parallel to decrease impedance. Example: two 4Ω speakers in parallel result in a 2Ω load.
- Series/parallel wiring: A combination of series and parallel connections can be used to achieve specific impedance loads.
Power Connection Leads
General Notes:
- Connect the +12V power input lead only after all other leads are connected.
- Ensure the ground wire is securely connected to a metal part of the car to prevent malfunctions.
- The REMOTE terminal turns the unit on when +12V is applied. A thinner wire (e.g., 18 Gauge, yellow) is acceptable for this connection. This terminal can be driven by the power antenna control wire of the car stereo. If the power antenna wire is in use, splice into it.
- Use a fuse in the power supply lead with a value matching the original fuse.
- Place the fuse as close as possible to the car battery.
- For full power operation, use leads of at least 10-Gauge (AWG.10) for the +12V and GND terminals.

(Diagrams illustrate power and speaker connections for various models and configurations, including single subwoofer, dual subwoofer, 4-channel, and 8-channel setups. These diagrams show the placement of input, output, power, remote, and ground terminals, as well as connections to the head unit and speakers.)
Recommended Fuse Sizes:
- TAS3000.1: 200A (External Type FUSE)

- TAS700.4/TAS2250.4: 100A (External Type FUSE)
- TAS1500.8: 100A (External Type FUSE)
Grounding Instructions: Keep ground connections as short as possible and of equal length, no longer than 20" (50 cm).
Troubleshooting
| Symptom | Possible Cause | Action to Take |
|---|---|---|
| No Output | Low or no remote turn-on input | Check remote turn-on voltage output at amplifier and correct as needed. |
| Fuse blown | Check power wire integrity and reversed polarity; repair and replace fuse as needed. | |
| Power wires not connected | Check power wire and ground connections; repair or replace as needed. | |
| Audio input not connected or no output from source | Check input connections and signal integrity; repair or replace as needed. | |
| Speaker wires not connected | Check speaker wires; repair or replace as needed. | |
| Audio cycles on and off | Speakers are blown | Check system with known working speakers; repair or replace speakers as needed. |
| Thermal protection engages when amplifier heatsink temperature exceeds 90°C | Ensure proper ventilation for the amplifier and improve ventilation as needed. | |
| Distorted Output | Loose or poor audio input | Check input connections and repair or replace as needed. |
| Amplifier level sensitivity set too high; exceeding maximum output capability of amplifier | Reset gain referring to the tuning section of the manual for detailed instructions. | |
| Impedance load to amplifier too low | Check speaker impedance load. If below 2Ω stereo or 4Ω mono, rewire speakers to achieve a higher impedance. | |
| Shorted speaker wires | Check speaker wire connections; repair or replace as needed. | |
| Speaker not connected to amplifier properly | Refer to the installation section of this manual for detailed instructions. | |
| Distorted Output (cont'd) | Speakers are blown | Check system with known working speakers and repair or replace as needed. |
| Poor Bass Response | Speakers wired with wrong polarity causing cancellation at low frequencies | Check speaker polarity and repair as needed. |
| Crossover set incorrectly | Reset crossovers referring to the multi-cross crossover configuration section of this manual for detailed instructions. | |
| Battery Fuse Blowing | Impedance load to amplifier too low | Check speaker impedance load. If below 2Ω stereo or 4Ω mono, rewire speakers to achieve a higher impedance. |
| Short in power wire or incorrect power connections | Check power and ground connections and repair as needed. | |
| Fuse used is smaller than recommended | Replace with proper fuse size. | |
| Too much current being drawn | Check speaker impedance load. If below 2Ω stereo or 4Ω mono, rewire speakers to achieve a higher impedance. | |
