2. Setup and Installation
Proper installation is crucial for optimal performance. If you are unsure about any steps, it is recommended to consult a professional car audio installer.
2.1 Before You Begin:
- Ensure the vehicle's battery is disconnected to prevent electrical shorts.
- Gather necessary tools: screwdrivers, wire strippers, crimpers, drill (if needed), mounting hardware.
- Verify speaker size and mounting depth (Woofer Mounting Depth: 2.063 inches) are compatible with your vehicle's speaker locations.
2.2 Installation Steps:
- Remove Existing Speakers: Carefully remove door panels or speaker grilles to access the factory speakers. Disconnect the wiring.
- Prepare Mounting Location: Clean the mounting surface. If necessary, use the provided template (if included) to mark and drill new mounting holes. Ensure there is sufficient clearance for the speaker's depth.
- Connect Wiring: Connect the positive (+) speaker wire from your amplifier/head unit to the positive terminal on the THUNDER65 speaker, and the negative (-) wire to the negative terminal. Ensure connections are secure and insulated.
- Mount Speakers: Place the THUNDER65 speakers into the mounting location. Secure them using the provided screws or appropriate mounting hardware. Do not overtighten.
- Adjust Tweeter (Optional): The pivoting tweeter can be angled up to 15° to direct sound towards the listening position for improved imaging. Gently adjust the tweeter dome to the desired angle.
- Reassemble: Reinstall speaker grilles and door panels.
- Reconnect Battery: Reconnect the vehicle's battery.
3. Operation
Once installed, the MTX THUNDER65 speakers operate as part of your car's audio system.
- Power On: Turn on your car's head unit or amplifier.
- Audio Source: Select your desired audio source (radio, CD, Bluetooth, etc.).
- Volume Adjustment: Start with the volume low and gradually increase it to a comfortable listening level. Avoid excessively high volumes that cause distortion, as this can damage the speakers.
- Audio Settings: Adjust bass, treble, balance, and fader settings on your head unit or amplifier to optimize sound quality to your preference. The THUNDER65 speakers are designed for rich bass, so fine-tuning these settings can enhance their performance.
4. Maintenance

- Cleaning: Periodically wipe the speaker grilles and surrounds with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Environmental Protection: While designed for car environments, avoid exposing speakers to excessive moisture or extreme temperatures.
