Does it fit my car?

Select your car

Find what fits your car

Can't find your exact car?

If you've replaced the radio in your Ford, Lincoln or Mercury, you've heard an audible "thump" sound when you turn on the power. The reason? Your Ford radio sent 5 volts to turn on the factory amp, not the 12 volts that your new car stereo delivers. In other words, the amp is simply getting too much juice.

This AFDI-5V converter from Axxess will drop that voltage down to 5 volts, which the factory amp can handle better for an easier (and quieter) start. Warranty: 60 days.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Crutchfield Customer Review (What's this?)

This part was recommended because I was replacing a receiver in a Mach 460 sound system from a Ford Mustang. These are notoriously tricky sound systems. This part prevents power surges (loud pops) from the subwoofer when you power on the receiver. It works perfectly. In fact, my sub had a quiet, but noticeable, thump when I powered up the factory receiver. Now there is no sound at all. Better than factory!

Pros: Works exactly as described

Cons: None

This is used to convert the power to 5v to the factory amp turn on lead. It stops the amp from thumping or popping when the unit comes on.

Necessary for Fords and like cars that use a 5V turn on instead of 12V. Kudos to Crutchfield for noting this when I ordered my stereo. Simple connection in-line to the power wire, and no annoying loud "POP!" when you start the car.

Pros: Like it says, cheap, easy, works.

Cons: Having a car that requires this thing. Looking at you, Ford!

Crutchfield Customer Review (What's this?)

Use of this "converter" was the most frustrating part of installing my new radio. There are no good directions. I had to search on the internet and finally found a picture showing which wires went where. Then I confirmed this with a Crutchfield advisor. Yet I still hear an occasional pop turning on the radio. Crutchfield does a fantastic job with every other aspect of radio installation. Why forget about this one?

Pros: Less popping, I suppose

Cons: Minimal and useless directions.

Worked flawlessly, i am not sure why people find three wires hard to connect, but If you have any kind of experience or common sense, this is a simple fix for Ford Amp pop.

Pros: nicely packaged, small, and plenty of pigtail to tuck it wherever you need it.

Cons: None, everyone else finds it hard to install.

Works perfectly-no popping!

Get Rid of the POP

Written by: OlYeller01 from Kingsville, TX on July 25, 2013

Crutchfield Customer Review (What's this?)

Ford vehicles with premium factory audio systems have a lower voltage remote turn-on for their factory amps than the 12 volt turn-ons in most aftermarket decks. Without a converter, turning on your ignition with an aftermarket deck gives you a VERY loud "POP" through your speakers. Besides being shockingly loud, the pop makes your whole sound system seem cheap.

This converter is extremely simple to wire up and eliminates the annoying pop. It's definitely worth the money. Don't even THINK of installing an aftermarket deck in a Ford with a "Shaker" audio system without this converter.

Pros: Eliminates the pop Low cost Super easy to install

Cons: None

Volt Reduction Harness

Written by: Eric from Salt Lake City, UT on May 11, 2013

Crutchfield Customer Review (What's this?)

Either this items does not work or we hooked it up wrong. I am guessing we hooked it up wrong. The instructions for this item were probably the some of the worst we have encountered. It appeared that they used different terminology for some of the wires than JVC did for their wires. Needless to say, we hooked it up but the "pop" is still there and is annoying. I have no desire to spend another 2-3 hours trying to fix it, and I'm not sure I could anyway.

Pros: At this point there are none. Just a waste of money.

Cons: Instructions are not clear. Item is not working as advertised. As I said above, terminology used for the wires is not the same. I think if you do this sort of thing all the time you probably won't have an issue. For all I know it is hooked up correctly and just doe not work but I may never know.

I had no idea that anything like this was even necessary. It has been over 30 years since I've installed a stereo into a car but Crutchfield made the experience as easy as could be. This harness drops the amp voltage from 12 volt to 5 volt and eliminates the loud pop at boot up if you have too much voltage. Works perfectly!

Pros: Simple straightforward easy installation.

Cons: None!

They all can' be perfect.

Crutchfield Customer Review (What's this?)

The piece was sent separately after I described a loud popping noise comming from my new Kenwood CD receiver. After installing it, the stereo no longer worked. (The technician told me it should have been included in the installation package so it was free.) Trouble shooting it with the technician revealed it was defective. They offered to replace it but also suggested if i was in a hurry, i could get one off the shelf at a local electronics store. I was in a hurry... The point of this is the invoice sent with the Axxess listed it at over $$ while down the street it cost $. Granted, I had to solder 3 wires and cover it with a piece of heat shrink but for the price and 10 minutes work, well, it was a good thing it was free.

Pros: Preassembled, ready to go and it will eliminate the "pop".

Cons: I was defective. (and potentially expensive)

Since this came for free with my receiver, I can't gripe. I didn't try the system without it, so I can't say for sure that it was needed. What I do know is that I don't get a voltage pop and it performed without a hiccup.

Product Research

Features

Overview: When replacing factory radios in vehicles with factory installed amplifiers (mainly in Ford, Lincoln, and Mercury vehicles), an audible "pop" through the speakers may be heard; especially the subwoofer. The main reason for this "pop" noise is that the factory amplifiers do not require 12-volts to turn on, but instead require 5-volts. The Axxess AFDI-5V 12-volt to 5-volt converter takes a normal 12-volt turn-on from an aftermarket head unit and drops it down to 5-volts, which the factory amplifier handles better. A 3-wire hook-up makes the AFDI-5V simple to install.

  • Connect the Blue/White wire to the aftermarket head unit's amplifier turn on wire.
  • Connect the Black wire to chassis ground.
  • Connect the Blue/Red wire to the vehicle's factory amplifier turn-on wire.
