This document describes the Pioneer TS-WX205A Amplified Bandpass Subwoofer, a car audio component designed to enhance bass reproduction in vehicles.

Function Description:

The TS-WX205A is an amplified bandpass subwoofer, meaning it integrates both the subwoofer driver and an amplifier into a single enclosure. The bandpass design utilizes a sealed internal chamber and a ported external chamber to achieve a focused and efficient bass response over a specific frequency range. This design typically offers higher efficiency and better protection for the speaker cone compared to open-air or sealed enclosures. The integrated amplifier simplifies installation by eliminating the need for a separate external amplifier, making it a convenient all-in-one solution for adding powerful bass to a car audio system. It supports both RCA input (for pre-out signals from a head unit or external amplifier) and speaker line input (for direct connection to existing speaker wires), offering versatility in integration with various car audio setups.

Usage Features:

The TS-WX205A is designed for straightforward integration into a vehicle's audio system.

Flexible Input Options: It offers both RCA and speaker line inputs, allowing it to be connected to a head unit with pre-out connections or directly to the vehicle's existing speaker wires if pre-outs are unavailable. This makes it compatible with a wide range of factory and aftermarket head units.
Integrated Amplifier: The built-in amplifier eliminates the need for a separate external amplifier, simplifying wiring and installation, and saving space in the vehicle.
Bandpass Enclosure: The bandpass design is known for its efficiency and ability to produce strong, focused bass, which is ideal for car audio environments. The enclosure also provides physical protection for the subwoofer driver.
Installation Accessories: The manual includes a packing parts list with items like a parts bag (containing screws), a belt assembly for securing the unit, and a cord poly assembly (including various power and signal cords), suggesting that necessary installation hardware is provided.
Remote Control Input: For RCA input systems, a system remote control input cord (blue cord included) is used to turn the unit ON/OFF in conjunction with the head unit's remote output. This ensures synchronized power management with the rest of the audio system.
Power Connection: The unit requires a direct connection to the car battery (10A fuse recommended) for its main power supply, and a separate accessory connection (0.5A, from the car's fuse unit) for the speaker line input system, or a remote turn-on signal for the RCA input system.
Grounding: Proper negative grounding to a metal part of the car body is crucial for normal operation and to prevent abnormalities.

Maintenance Features:

Service Manual Availability: The document itself is a service manual, indicating that detailed information for repair and maintenance is available.
Exploded Views and Parts List: The manual provides exploded views of the main unit and a comprehensive parts list, including part numbers and remarks (e.g., "NSP" for parts generally unavailable, or a mark indicating safety-critical parts). This is invaluable for identifying and ordering replacement components.
PCB Connection Diagrams and Schematic Diagrams: Detailed diagrams of the PCB (Printed Circuit Board) connections and schematics are provided for both the AMP UNIT and SWITCH UNIT. These are essential for troubleshooting, diagnosing electrical issues, and performing component-level repairs.
Resistor Code Conversion: Instructions are given on how to convert resistance values into code form for ordering resistors, which is a practical detail for technicians.
Safety-Critical Parts: The manual highlights parts marked with a specific symbol, indicating their importance for safety. When replacing these, identical designation parts must be used to maintain safety standards.
Specifications Subject to Modification: A note indicates that specifications and design are subject to modification without notice, which is common for electronic products and implies that users should refer to the latest available documentation for the most accurate information.
