Universal 12V to 5V Step Down Converter by Axxess®. The AFDI-5V will take a 12V input from aftermarket radios remote turn on and drop the voltage down to 5V this is used in some vehicles that have an amplified sound system the OEM amplifier can use a 12V input to turn on however an audible pop may heard using the AFDI-5V will eliminate that audible pop.



3-Wire hook up drops 12 V turn on signal to 5 V


  • For use in vehicles with OEM amplifier and aftermarket radios
  • Fixes audible "Pop" when Aftermarket Radio turns on OEM amp

AFDI-5V is an accessory for the following products: XSVI-5520-NAV Non-amplified, non - onstar interface harness that retains accessory power and provides navigation output wires.

OEM Ford radios send only 5 V to the stereo amplifier to turn them on, a signal separate from the amp's 12 V supply current. Problem is, the aftermarket radio has 12 V on that line, far more than is necessary. It won't hurt anything, but it often causes an audible "pop" when the radio is turned on. This simple harness drops the 12 V from the radio to 5 V, quieting the "pop". Just connect one wire to the 12 V radio sense line, one to ground, and the last to the amp's sense line.

Axxess® Integrate, a subsidiary of mobile audio's one-stop-shopping conglomerate Metra, is at the very forefront of the mobile audio installer's field. Their cutting-edge interfaces make adding to or installing a car stereo, nav system, sat radio or auxiliary amplifier easy. With the complexity of modern vehicles, it's not a simple operation to install aftermarket electronics that will properly interface with the car's wiring, onboard computers and OEM infotainment system. Axxess has it figured out and dialed in.

Finally the Pop Is Gone!
Axxess® - 12 Volt To 5 Volt Step Down Converter
I have a 2006 Ford Mustang which someone had installed in aftermarket stereo in but retain the factory amplifiers. Every time he would start the car up you would get the dreaded "POP" from the sub woofers due to the level of voltage the aftermarket stereo sans to the amplifiers. I ordered this step down converter at the suggestion of one of my friends and boy was he right. This product once installed and lemonade and that awful "POP" when starting my vehicle and now I don't have to cringe every time I do. If you are experiencing the same problem in your Ford vehicle I would highly recommend this product. You do have to do some wiring with this so just be aware.
