The instructions are on the back of the card if you buy it at Radio Shack.

There is a picture of it here

sorry to revamp a 5 year old thread but I just bought a 2006 F-150 with the factory amp and sub. The guy I bought it from put an aftermarket headunit in and sure enough I have the popping sound going on almost constantly.

I have the 12-5v adapter coming in, but am confused by the instructions. It seems like everything between the head unit and the factory wiring will be connectorized and the instruction will be asking me to splice in the adapter, creating parallel paths.

does anyone have a picture of how these 3 wire adapters work/install?

Instructions are:

Wiring the AFDI-5V:
1. Connect the Blue/White wire to the aftermarket radio’s amplifier turn on wire.
2. Connect the Black wire to chassis ground.
3. Connect the Blue/Red wire to the vehicles amplifier turn on wire.

Old thread, new car

I know this is a really old thread, but I was hoping that one of you might know the answer to my question.

I recently bought a 2004 Expedition from my uncle and installed an aftermarket head unit. I am experiencing this popping sound from my subs, and one of them actually appears to have blown and makes a constant buzzing noise that is extremely annoying. Since the subs are so old and don't sound very good, and don't really put out the punch I'm looking for, I was planning to replace them anyway, so the driver side sub blowing isn't that big of a deal.

My question is: If I replace the subs, will that alone fix the popping sound, or will I still need to install a voltage regulator? And, should I also replace the subwoofer amplifiers as well?

Also, if anyone has recommendations on what subs and amps I should replace the old ones with, that info would be greatly appreciated! I'm not sure which subs I will replace the old ones with, but I really liked my old Kicker 10" subs that I had in my Dodge Ram. Also considering Pioneer, since my head unit is a Pioneer.

Thanks in advance to anyone who replies. Below are some links to subs I was looking at. No idea which amps to get, or what the correct amperage and ohms are needed either.
