Installing aftermarket deck with factory sub

[Heineken]

Well, the deck works, but I do get a pop sound when the amp fires up. It akso looks like I need an antenna adapter or something cause the focus one definitely don't fit.

Mind sending me the fix when you have a chance?

My sub pops too...i ignore it.

well, i dont want to. if it was a small pop i wouldn't care but if it can be fixed then I want to fix it.

The sub making a popping sound when you turn on the amp sounds like it's the amp itself. Nothing wrong with it.

Most amp's have a muting circuit that mutes the amp for the first few seconds of startup to eliminate that popping sound. Sounds to me like yours just doesn't have that feature.

I don't think that's the case - if it was then the sub would pop with my factory deck in as well. Keep in mind here I'm using the factory sub, and the popping only happened once i put an aftermarket deck.

I researched the issue online and the common fix is to install a resistor/capacitor that causes a delay in the amp turn on.

If you are using the factory amp as well, then that's probably the reason. The factory HU should have a minor delay to turn on the amp and probably mutes it as well from the HU. Since your aftermarket deck doesn't do that, you have popping.

the problem is most ford factory amps use a 5 or 6 volt turn on. All aftermarket head units use a 12v turn on which causes the popping sound. If you drop the voltage down it will eliminate the pop.

Not sure if that's the reason.

But if it was then add a resistor in line with the remote lead. A 1.5k ohm resistor should be ok.

what wires would you have to splice to make the sub work without the harness or do u need the rca cables

[dirtbiker348]

Can somebody help me with hooking up the factory sub to an aftermarket hu. I bought the adapter that was posted in this thread and the plug that comes out of the rca wires doesnt plug into anything. Theres two blue wires that come off and i think i have them in the right spot but im not totally sure. Theres a third factory harness that isnt plugged in and i believe this is for the sub but the rca plug isnt going to plug into it. What am i doing wrong or was that the wrong harness posted??
