Line in from 3rd row tweeters?

[EX-excursion]

Hey all... Asking for a little advice - help on the 2015 Expedition. We have the woofer in the rear & premium sound system- all stock. All over this site I see others curing the 3rd row sound problem in different ways. As for me I want to try something a little different, but don't want to blow $$ or start down a road just to find out things aren't what I think they are.

Here's what I'm planning. I want to tap into each rear tweeter set of speaker wires & use each side for a 'line in' to an appropriate relatively SMALL amp. So...to clarify...tap into the right side, run wires to a small amp. Tap into the left side, run wires to the same amp. From there, I'll install a couple of good quality 6X8's or maybe some 6 1/4" round COAXIAL or TRIAXIAL speakers.

Question one: do the wires on the rear tweeters contain 'all the music' (base, mid & high range sound)???

Question two: (wanting to remove as few panels as possible)........can anyone 'target' me to these tweeter wires where they might run very close to some easily accessible area where I might be able to pry a panel corner up, hook them and tap into them?

QUESTION THREE: Also a big deal, I want to put a simple 'on/off' toggle on that damn factory woofer.. Can anyone advise along the same lines? (easiest access to the woofer wires-which exact color wire to put the switch on)

This is all for the kids- the two that ride in the rear seat can only hear that crappy factory woofer- even when I turn the base down as far as possible and keep the volume low. I simply want a couple regular 2 or 3 way speakers back there with maybe 75 watts going to each one. Thanks all....

#1...no they don't..tweeters run ur high frequencies so no mid bass and the sound is high vocals...that is a BAD choice to tie in to add speakers...I would tap the rear door speakers

#2...can't help

#3...u will have to remove a lot of panels which contradicts u wanting to remove a lot of panels

To do this right and properly...u have to remove the panels...

Thanks 10K. That's the biggest deal right there (#1). I was thinking this might be the case (having to tap in to the rear doors).

I swear to God I'm about ready to stick a few screw drivers right into that rear woofer, lol..... I have to get a switch on that thing, so if anyone knows more about that, please holler up!

Heres the stereo wiring for your 2015.

This doesnt list which wires are your power and ground to the factory amp. From what I can tell the stereo is run all off the same amp so turning it off is a no go. My thinking is simply put a relay on each ground with to the sub VC and activate those with the same switch.
