Frequently Asked Questions - DR-1325.4D Crunch
How do I connect the receiver to my car's power supply?
Connect the yellow wire to the constant 12 V battery line and the red wire to the accessory switched 12 V. Always connect the black ground wire to the vehicle chassis. Use correct fuses as specified.
Why does the receiver turn off when I increase volume?
This is often caused by a low battery/alternator voltage or a loose ground connection. Check the power wiring, the ground connection, and the speaker impedance; do not exceed 4 ohms per channel.
How can I pair my phone via Bluetooth?
Enable Bluetooth on your phone, select CRUNCH DR-1325.4D in the available devices, and enter PIN 0000 if prompted. Once pairing is successful, the receiver will remember the device.
What file formats are compatible with USB playback?
The USB port supports MP3 and WMA audio files. The USB drive should be formatted in FAT32 and the files should be organized in folders no deeper than 8 levels.
How do I reset the receiver to factory settings?
Press and hold the RST button on the front panel for 5 seconds. This restores all settings to factory defaults and clears the Bluetooth pairing memory.
Does the receiver support rear-view camera input?
Yes, the receiver has a rear camera input on the RCA connector. The camera image is automatically displayed when the reverse gear is engaged and the camera trigger wire receives +12 V.
Why is there no sound from one speaker?
Check the speaker wiring, the fader/balance settings, and the speaker itself. If necessary, swap the speaker to another output to determine if the issue is the internal amplifier.
How should I clean the receiver's screen?
Use a soft, dry microfibre cloth to gently wipe the screen. Do not use alcohol, ammonia, or abrasive cleaners, as they may damage the anti-reflective coating.
Can I use this receiver with a 24 V truck electrical system?
No, this unit is designed for 12 V negative ground systems. For 24 V trucks, use a voltage converter or an external DC-DC step-down regulator rated for the receiver's current draw.
Where can I obtain spare parts and accessories?
Spare parts and accessories, such as mounting sleeves, wiring harnesses, and faceplates, are available from authorized Crunch dealers and service centers. Contact Crunch customer support for the nearest outlet.
