I have decided to start making preperations for my Subwoofer and need to know where the Preamp is located for my 2003 Ford Ranger FX4--it has a 6 CD Disc Changer if that helps anything. I am sure there is one, and all I need is a confirmation before I get to deep into this project.

Its on the back of the stock head unit right? So all I need to do is pull out the Head Unit, plug it my wire in, connect that into my Amp and go from there right?

I am looking for the Audio-Out port of the Stereo system, and it didnt say anything about it in my Owners Manual.

Thanks in advance. . .

 

There is no external factory amp on an FX4. It's in the head unit. If you want to use an external amp with it, you will need a line output converter unless your amp will accept speaker level inputs.

 

Alright, fair enough.

A little something like this might be the fix?

I am guessing the route most go is getting an After Market Head Unit, which has a RCA output on it?

 

Youll get a cleaner sound with a aftermarket headunit rather than a line out conv.

 

I suppose thats true, the stock head unit is decent - but I will look into a after market head unit, because I really dont want to go halfway, so its either all or nothing, by that I mean a $300 color LCD or just use the little converter for now.

If you want to retain the factory head unit and avoid the LOC, look for an amp that will accept speaker level inputs. My Roc-Fos amp has provisions for either preamp RCA inputs or speaker level inputs from the factory HU.

 

i had the converter on my stock head unit before i went aftermarket and there was a big difference. if you are putting a bigger amp in your truck then it will actually rob a little bit of your speakers. plus, aftermarket sounds a whole lot clearer.

these converters can be found at your local radio shack if you decide to head that route.

 

what do you mean 300 dollar LCD i dont you dont mean a pyle flip out tv!!!! That probably puts out the equivalent of the line out not if worse
