Frequently Asked Questions - Road Thunder Extreme RTX2BT MTX Audio
How do I pair my phone with the RTX2BT via Bluetooth?
To pair, turn on the speaker system and activate Bluetooth on your smartphone. Search for MTX RTX2BT in your device list and select it. The LED indicator will flash during pairing and turn solid once connected. If a PIN is requested, enter 0000.
What power source does the Road Thunder Extreme RTX2BT require?
The system is designed for 12V DC power from a vehicle, boat, or ATV battery. Use the included wiring harness and connect the red wire to positive and black wire to negative. The inline 5A fuse protects against power surges.
Are these speakers waterproof?
Yes, the RTX2BT features an IPX5 rating, meaning they are protected against water splashes from any direction. They are perfect for outdoor powersports vehicles, but not designed for prolonged submersion. Always install with the grille facing forward to keep connections dry.
How do I clean the speakers?
Use a soft, damp cloth with mild soap and water to wipe the exterior. Avoid abrasive cleaners and pressure washers, which can damage the UV-protected ABS housing. Keep the speaker grille free of debris to maintain sound quality.
Can I use these speakers without a vehicle battery?
You can use a 12V battery or an independent power supply as long as it provides stable DC current. For testing at home, a regulated 12V adapter with at least 2 amps output is recommended. Never exceed 15V.
What is the difference between peak and RMS power on the RTX2BT?
RMS power (100W) is the continuous power the speakers can handle without distortion, while peak power (200W) is the maximum short-term burst. The built-in amplifier delivers 50W RMS per channel for reliable performance.
How do I reset the Bluetooth connection?
Turn off both the speaker and your source device. Press and hold the Bluetooth button on the controller for 5 seconds until the LED flashes red and blue. This clears the pairing memory. You can then re-pair using the standard procedure.
Can I mount these speakers on a boat?
Yes, the marine-grade build and corrosion-resistant grilles make them suitable for freshwater and saltwater environments. Ensure you use stainless steel mounting screws (included) and seal any holes with marine sealant to prevent water ingress.
What is the warranty coverage for this product?
MTX Audio provides a 1-year limited warranty covering defects in materials and workmanship. Register your product online to activate. The warranty does not cover damage from misuse, water submersion, or unauthorized modifications.
How do I tune the sound output?
Use the volume and track controls on the wired remote or your connected phone. For tonal adjustments, access your device's equalizer to tweak bass and treble. The speakers are optimized to deliver balanced audio without external amplifiers.
