need wiring info for a sub

[2008fx4]

im thinking of taking out the factory sub and installing something with a little more kick. however, i need to know if there is a way to tap into the factory wiring back by the sub to wire in a line level adapter to get the signal to the amp (via rca cables). im sure that i could tap into the rear speakers, but that just seems like a lot more work to get all those panels off.


can anyone help????

Wow had no idea the 08's had a factor sub in them. Learn somthing new everyday I guess

They only do if you upgraded to the Audiophile system with sub...

I may be able to help. Can you give me some more specifics? I really don't know how the factory system is set up, but if you tell me what components you are planning on using I might be able to help.

Are you going to use an amp with hi-level inputs? If so, you can clip the factory sub input wires to the sub itself downstream of the factory amp, R&R the old sub, run the clipped wires to the "hi-level" input on the new amp, and then run the outputs on the new amp to the new sub. You'll probably need to run an install kit on the new sub since most aftermarket subs draw much more current than factory units. Are you going to get a class D amplifier?

If you are not going to use an amp with hi-level inputs, you'll have to get an adaptor to input them to the RCA inputs on the new amp.

What amp, what sub? Are you installing a capacitor too? What install kit? Factory deck?

ended up using a line level adapter off of the rear speakers. that converted the signal to use rca wires, then wired up an alpine mono amp to a 10" fosgate punch p1 in a wedge shaped truck box. remote wire off the back of the factory nav was a solid blue wire. sounds a lot better than stock, but now i want a 12" sub. oh well.

do you have the rear power sliding window?

The power slide window takes up some extra space behind the seat. Those of that have the power window get screwed with trying to fit something back there.

The factory sub doesn't sounds bad, but I think and upgrade would sure be nice.

Can you post some pictures of your install?

Yeah I ran into that same problem with mine....I want to put my subs behind the seat in the back, but the power window takes up way too much room....once I get the lift and tires squared away, I'm just puttin a 12" in the center console

i didnt take any with the seat out. i guess i could take some with the seat in place, but that wont show all the work that needed to be done
