What's in the Box
Your JBL Stage 602 speaker package includes the following components:
- 1 pair of JBL Stage 602 coaxial speakers
- Speaker grilles
- Mounting screws

Setup and Installation
Proper installation is crucial for the performance and longevity of your speakers. Follow these general guidelines:
- Preparation: Before starting, ensure you have all necessary tools (screwdrivers, wire strippers, drill, etc.) and verify the speakers fit your vehicle's designated speaker locations.
- Remove Existing Speakers: Carefully remove the factory speakers from their mounting locations. Disconnect their wiring.
- Mounting: Place the new JBL Stage 602 speakers into the openings. Use the provided mounting screws to secure them firmly. Ensure there is no interference with window mechanisms or other vehicle components.
- Wiring: Connect the speaker wires to your vehicle's audio system. Pay close attention to polarity: connect the positive (+) terminal of the speaker to the positive (+) output of your amplifier or head unit, and the negative (-) terminal to the negative (-) output. Incorrect polarity can lead to poor sound quality.
- Test: Before reassembling interior panels, temporarily connect the battery and test the speakers to ensure they are functioning correctly.
- Reassemble: Once confirmed, reassemble all interior panels and grilles.


Operation
Once installed, your JBL Stage 602 speakers are ready for use. Follow these steps for optimal audio experience:
- Head Unit Connection: Ensure your speakers are properly connected to a compatible car stereo head unit or amplifier.
- Audio Settings: Adjust the bass, treble, balance, and fader settings on your head unit to achieve your preferred sound profile.
- Break-in Period: Allow a brief break-in period (typically a few hours of normal listening) for the speaker components to settle and deliver their full acoustic potential.
- Volume Control: Operate the speakers within their rated power handling (45 Watts RMS, 135 Watts Peak) to prevent distortion and damage.
Maintenance
To ensure the longevity and continued performance of your JBL Stage 602 speakers, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe down the speaker grilles and surrounds. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the speaker materials.
- Inspection: Periodically check the speaker connections to ensure they are secure and free from corrosion.
- Environmental Protection: While designed for automotive use, protect the speakers from excessive direct sunlight, extreme temperatures, and prolonged exposure to moisture.
