Overview

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.

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.

Excellent construction, will install this Friday.

Crutchfield Customer Review (What's this?)

This was supposed to eliminate the POP in the subwoofers, when you turn on the radio by dropping the 12 volt signal, down to the 5 volts needed. I wired according to the schematic, but I still hear a POP (not that loud) when the radio first comes on. Radio works fine otherwise, and the POP isn't a big deal to me. According to the wiring directions it appears to be a parallel connection, which is how I wired it. Maybe I didn't wire it correctly, so I gave it the benefit of doubt and 3 stars.

Great product if the new radio applies wrong voltage to turn on wire for factory installed amplifiers. Too high voltage made the factory sub-woofer thump very loud when turned on. This device solved the problem.

Reduces the 12-volt DC to the 5-volts required by speakers don't absorb the full thrust. In a manner of speaking, it's a safety device for stock 35 -55 watt speakers. The Axxess AFD-5V should be used in any good quality install.

Pros: Reduces or eliminates excess voltage to speakers.

Cons: None

Crutchfield Customer Review (What's this?)

This did exactly what it was intended to do, keep my factory amp/sub from the dreaded pop when powering on. The only problem I faced was that the wire coming from my new head unit was solid blue instead of blue with white stripe as stated in the instructions. My particular head unit apparently had the color coding backwards where the power antenna lead was blue with white stripe and the amp lead was solid blue. I guess most head unit wiring is color coded the opposite way. Other than that it did what it was supposed to do.

It works, but not entirely. There is still a "pop" or "thump" noise every now and then. The wiring is all soldered correctly. I didn't want to cut and wire/solder so I am just dealing with it. It happens randomly mainly, when I shut off the car.

Pros: Prevents the "pop"/"thump" noise on almost every command change.

Cons: Still has "pop"/"thump" noise mostly when the car is turned off.

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

Very easy item to wire, worked perfect in my 2005 F150. 3 wires to wire, 1 to ground (I just wired to stock ground wire) 1 to the wire harness and the other to the reciever sub/amp wire harness. The wire harness install sheet tells you color for color the specific wire.

Pros: Easy to wire, free, works

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. If you wire your head unit to the Ford factory amp without this you will get popping and or thumping at power up.this simply prevents it and is free with the purchase of a head unit.

Pros: It works as described

Decent design with plenty of wire to make sure it fits without adding any wire. Instructions could be clearer, but with Crutchfields help center (which i didn't use lol) and some basic wiring knowledge, it can be figured out.

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!

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.

OlYeller01 from Kingsville, TX on 7/25/2013

2007 Ford Mustang
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

Eric from Salt Lake City, UT on 5/11/2013

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.
