Standard Technical Specifications
Works with 12V & 24V Systems
Perfect for cars, trucks, boats, and power sport audio. Integrated 2A fuse helps prevent damage from power surges or accidental short circuits. Note: The remote trigger output voltage matches the system's power input. If using a 24V system, ensure the connected amplifier can accept 24V trigger signals or add a voltage regulator to protect the amplifier.
Bluetooth 5.2 with Qualcomm QCC3040
Powered by the Qualcomm QCC3040 Bluetooth 5.2 chipset, blafili CAR offers faster wireless transmission, lower latency, and extended connection range — ideal for high-performance car, marine, and motorcycle audio systems.
Stereo RCA Output & Remote Trigger Wire Support (Music-Activated)
- The blue remote trigger wire provides an output only while audio is actively playing via Bluetooth. This feature ensures that your amplifier or powered speaker system is triggered only when needed, preventing unwanted power cycling during idle periods.
- RCA output ensures clean stereo audio transmission directly to your amp or powered speakers.
Premium Audio Codecs
Supports aptX Adaptive, aptX HD, aptX, AAC, SBC for Hi-Fi sound. While blafili CAR doesn't include a built-in EQ app, it seamlessly passes high-quality audio to your amplifier or head unit. To shape your sound—bass, treble, and more—simply use your phone’s or mixer’s EQ settings. For best results, pair it with an audio system that supports EQ adjustments.
ACC Auto Power-On Control
Turns on/off with your ignition – no manual switch needed. The blafili CAR Bluetooth receiver requires both the **+12V (or +24V)** power( YELLOW ) and the **ACC (accessory/ignition) line( RED )** to be properly connected in order to power on. Without the ACC line receiving voltage (typically when the ignition is on), the unit will remain off by design.
Easy Installation & Versatile Mounting Options
The compact design and included wiring make it easy to mount blafili CAR behind a dashboard, in a glovebox, or directly onto a wall. Perfect for custom car, marine, or motorcycle audio setups.
