Verify amplifier power light comes on and speakers operate when receiver volume is adjusted.
Ensure correct speaker output and verify wiring if sound is absent or incorrect.
Prevent 'siren' sound by not bundling cables, running wires separately, and ensuring good grounds.
Run power wires along existing vehicle wiring paths in the trunk, removing trim as needed.
Use wire ties to bundle wires, keeping power and speaker wires separate for optimal performance.
Strip 1/4 inch insulation, insert into connector, and crimp securely for reliable splices.
Run power and speaker wires on opposite sides of the vehicle to prevent noise induction.
Check +12V and remote wires for power. Verify fuse status.
Adjust input level control (gain) to a higher setting if radio volume is too high.
Adjust input level control to a lower setting if radio volume is too sensitive.
Check speaker connections, wiring integrity, and for defective speakers.
Adjust input level, check speaker wiring for shorts, and ensure RCA cables are functional.
Verify power wire connections and check speakers for shorts or defects.
Ensure proper ground connections and separate power/speaker wires to avoid ignition noise.
Check remote wire connection; consider a switch for manual amp turn-on if needed.
Allow amplifier to cool if in thermal protection; check speaker connections and impedance.
Verify speaker wires are connected correctly to speakers and inputs are properly hooked up.

The Jensen XA2150 is a two-channel, 300-watt total system power automotive amplifier designed to enhance the audio experience in a vehicle. This amplifier is built to make the sound of your receiver fuller and richer, even at low volume levels, and allows for the use of more powerful speakers by delivering substantial wattage per channel.
The primary function of the XA2150 amplifier is to boost audio signals from a car's receiver to drive speakers with greater power and clarity. It features RCA inputs for low-level audio signals and high-level inputs for direct connection to speaker outputs from a receiver, offering flexibility in integration with various car audio systems. The amplifier includes a continuously variable low-pass or high-pass crossover, allowing users to tailor the frequency response to specific speaker types, such as subwoofers (low-pass filter) or smaller full-range speakers (high-pass filter). A "full" setting is also available for full-range speakers, passing all tones.
A bass boost feature is incorporated, which increases the volume of bass by up to 6 dB at 45Hz, providing a more impactful low-frequency response. The amplifier also has a remote turn-on/off capability, which allows it to power on automatically when the car's receiver is turned on, simplifying operation.
For system expansion, the XA2150 includes pass-through connectors, enabling the addition of other amplifiers to the audio setup. Its bridgeable design allows the amplifier to direct its full power to a single speaker, typically a subwoofer, for enhanced bass performance.
The XA2150 is designed for flexible mounting, either under a seat or in the trunk, thanks to its compact design. Proper air circulation around the amplifier is crucial due to heat generation, so it should not be covered by carpets or enclosed behind trim panels. The installation process requires disconnecting the battery's negative terminal for safety. An amplifier installation kit is highly recommended, as it typically includes necessary components like RCA cables, power and ground wires, and a fuse or circuit breaker.
The amplifier supports both high-level and low-level inputs, but only one type should be used at a time.
Pass-through connectors (PASS OUTPUT) are available for daisy-chaining and adding other amplifiers to the system.
The manual provides diagrams for various speaker configurations, including two speakers, two subwoofers, two speakers plus a subwoofer, and a bridged subwoofer. It emphasizes the importance of using appropriate speaker wire gauges (12 gauge for subwoofers, 16-18 gauge for other speakers) and ensuring correct impedance matching (e.g., 4 ohms minimum for bridged operation).
After installation, several tests should be performed:
The XA2150 is equipped with electronic protection circuitry to safeguard against short circuits, DC offset, and thermal overload.
The manual includes a comprehensive troubleshooting guide to address common issues such as:
The guide provides possible causes and corrective actions, such as checking wiring connections, adjusting input levels, replacing defective speakers, insulating speaker wires, and ensuring proper grounding.
The Jensen XA2150 amplifier is designed for car audio enthusiasts looking to upgrade their in-vehicle sound system with a powerful, versatile, and protected amplification solution.
