Jared did you run your sub wires from the back of your head unit or did you get them from the back of the truck like Daedrix did? i don't know about the remote wire but it is a powered sub.

 

this is the converter i already have.

 

Yes, I did everything behind the dash and the radio harness.

 

is that easier or harder because the wires in the back seem like they would be harder to splice into what are the color of the wires I'm looking for behind the HU

 

Well, it isn't easy because the harness doesn't come out very far and it is hard to spice into. Also, the sub wires do not run to the wire harness behind the radio, they run to the factory amp, so if you are wanting to tap into the low range sub wires you will have to do it at the rear door.

I was able to make all the adjustments at my converter and my new amp so I just tapped into the wires that go to the front door speakers (not the tweeters, just the main door speakers). I don't think it matters if you tap into the rear speakers or the front, the main purpose of taping the speaker wires is to create RCA connections.

 

If you want to do it the way I did I will be happy to walk you through it. Just remember that if you run the RCA all the way from the front of the truck to the rear it will need to be extra long, because you have to follow the trim to hide it. Make sure you have at least a 10ft RCA cable

 

Here, this may help. It is a wire diagram for the audio system (in color).

So in the picture i posted earlier are the wires in question the ones bound by tape that are really thin or the ones behind the taped up wires?

 

If you have the Alpine system in your truck, here's a wiring guide:
2002 Land Rover Discovery with Alpine Wiring Information
I would tap into the system at the amp. The trick is going to be dealing with splitting the signals so you send the low frequencies to the subs while sending the highs to the factory amp. The input to the amp is full spectrum, then the amp crosses it over to split the signals. Does the subwoofer you are using have a built in amp or is the amp separate? Many amps can take a line-level input and most sub/amp combos can take a line-level input. Typically, amps have a low-level bypass so you can pass the rest of the signals off to another amp.

 

the sub I'm using has a built in amp it is a powered sub. i want to just untape the wires in the very back and splice those and re tape them up I'm assuming that will be the easiest way. now if i do it that way which set of wires is it as there are 2 sets in my little area not sure what to call it. if i tap into the amp would i just on the output side of it find the colors that are in that wiring diagram?

P.s how do i know if i have alpine or not
