The Kicker PT250 is a powered subwoofer enclosure designed for quick and easy integration into vehicle audio systems. This system aims to deliver substantial bass performance without the complexities typically associated with separate amplifier and subwoofer installations. The PT250 features a 10-inch subwoofer, a built-in amplifier, and adjustable controls for customization. This article details the technical specifications, installation procedures, and operational considerations for the Kicker PT250, based solely on the provided documentation.
Technical Specifications
The Kicker PT250 boasts several key specifications that define its performance characteristics. The subwoofer itself measures 10 inches (25 cm) in diameter. The amplifier provides a RMS power output of 100 Watts at 14.4V with 10% Total Harmonic Distortion (THD), and 90 Watts RMS at 14.4V with 1% THD.
Key dimensions of the enclosure are as follows:
- Net Weight: 18 lbs (8.2 kg)
- Height: 12-13/16 inches (325 mm)
- Width: 19-5/16 inches (490 mm)
- Depth at Top: 4-11/16 inches (118 mm)
- Depth at Base: 7-11/16 inches (195 mm)
The unit exhibits a frequency response of 25–120Hz ± 1dB and a signal-to-noise ratio exceeding 95dB. It incorporates a variable crossover, adjustable from 50–120Hz at a 12dB/octave lowpass slope, and a 24dB/octave subsonic filter at 25Hz. A phase switch allows for selection between 0° and 180° settings. Input sensitivity is specified as 125mV–5V for low-level inputs and 250mV–10V for high-level inputs. The system also includes KickEQ Bass Boost, which is variable up to +6dB at 40Hz, and a remote bass control. The enclosure type is sealed.
Installation Procedures
Proper installation is crucial for optimal performance and longevity of the Kicker PT250. The documentation emphasizes selecting a structurally sound mounting location. Careful inspection of the intended mounting area is required to ensure that mounting screws will not compromise the vehicle’s fuel tank, brake lines, or wiring. Interference with any mechanical components underneath the mounting surface should also be avoided.
A minimum of 4 inches (10 cm) of open ventilation space around the amplifier is recommended. Whenever possible, mounting the enclosure within the climate-controlled passenger compartment is advised.
The PT250 offers two automatic power-on modes selectable via a panel on the unit: +12V and DC offset. Utilizing the DC offset mode provides a +12V signal to the remote (REM) terminal, enabling the powering of additional amplifiers.
Operational Features and Adjustments
The Kicker PT250 provides several adjustable features to tailor the sound to individual preferences and vehicle acoustics. The phase switch allows users to correct for potential phase cancellation between the subwoofer and the vehicle’s existing speakers. If bass response is diminished, switching the phase can improve performance.
The unit accepts both low-level and high-level inputs. The input level switch should be set to match the output of the source unit. The variable crossover allows adjustment of the frequency at which the subwoofer begins to roll off, typically set around 80Hz as a starting point.
The input gain control is not a volume control; rather, it adjusts the source unit’s output to the amplifier’s input level. The recommended procedure is to set the source unit’s volume to approximately 3/4 of its maximum and then slowly increase the gain control on the enclosure until audible distortion is detected, after which the gain should be slightly reduced.
The variable KickEQ Bass Boost provides an adjustable boost of up to +6dB at 40Hz, allowing for further enhancement of low-frequency response.
Troubleshooting
The documentation provides limited troubleshooting guidance. If excessive distortion is observed, checking the grounding connections is recommended to ensure they are secure. If bass response is weak, adjusting the phase switch is suggested. If noise is present in the audio signal, a grounding wire connected from the RCA outputs of the source unit to the vehicle’s chassis may resolve the issue.
Safety Precautions
A caution is provided regarding jump-starting a vehicle. It is imperative to ensure correct connections when using jumper cables, as improper connections can result in blown amplifier fuses and potential failure of other critical vehicle systems.
Conclusion
The Kicker PT250 powered subwoofer enclosure offers a convenient solution for adding bass to a vehicle audio system. Its compact design, integrated amplifier, and adjustable features provide a balance of performance and ease of installation. Proper installation, careful adjustment of the controls, and adherence to the safety precautions outlined in the documentation are essential for maximizing the benefits of this product. The specifications and features detailed in this article are based solely on the provided documentation and represent the capabilities of the Kicker PT250 as designed and manufactured by Kicker.
