Default 2002 WRX install questions (long)

My cousin owns a 2002 WRX and wants to upgrade the stock system. I will be doing the installation and was wondering about a few things:

1. Are all the speakers standard (4 ohm impedance) or are they some wierd impedances? And are the speakers driven by an amp in the HU or is there an external amp somewhere?

2. how hard or easy is it to get the HU? any tips on taking it out? What kinds of install kits are out there? It will be a 1 DIN HU going in there at first and maybe ading a 1 din EQ afterwards. Any pics of suggestions of the nicest one (flush install hopefully)?

3. is there any way to mount an aftermaket tweeter in the stock location in the door? If not where have you guys mounted your tweeters? What size are the mids that are in the door? Any tips to taking the door panels off?

4. Any pics or recommended boxes for a nice stealthy install for a sub? Probably 1 12" in a sealed box.

5. Any recommendations on running wires? Any good places to run the power wire through the firewall?

Any info is appreciated. Thanks.

There's an unused 1.5" (or so) rubber grommet down near the clutch. I've used it for everything I've needed to wire. Just punch a hole and cram the wire(s) thru it and it'll make a pretty good seal. Add some silicone to really seal it off if you want, but I haven't had any issues with water leaving it alone.

taking out stock hu is a breeze...

I found its easiest to remove cupholder + trim piece first (open cupholder, then remove screws...trim + cupholder slides out

then next piece of trim (which surrounds radio and heater controls snaps out it you pry it gently.

you'll see HU is held by screws which once out allows the unit to slide out..

I believe spkrs are 4 or so ohms....nothing weird like my ford poopers

If you're replacing them (which is clearly the first priority upgrade) I'm not sure why you care, but yes, the are just normal POS paper speakers with whizzer cones, and are driven directly by the OEM headunit. Do a search on this forum for "door speaker" to find out important info about speaker size, mounting depth, and spacer rings. Look at Concillian's front door measurements first.

Really easy to get to and install/remove. Do a search for "trim DIN" on this forum; one of the threads you will find is:
http://i-club.com/forums/showthread.php?threadid=111982
which includes pictures of the "guts" as well as info on wiring harnesses and DIN pockets. Also, you should be able to sell the OEM HU/CD changer for a few hundred US$ in mint condition.

Speaker sizes and taking door panels off are covered in threads under #1 above. Tweeter mounting can be done in the stock location using two methods: 1) Make a bracket for your tweeter somewhat like the bracket that comes with the OEM tweeter and mount that to the door metal, or 2) mount the tweeter to the inside of the door panel, right behind the "waffled" area of plastic. #1 has been described in this forum previously; #2 is what I did and will post photos when I finally finish up (hopefully within a week or so).

Stealthy sub boxes really depends on what you want to trade off space-wise (e.g. toss spare tire and use that space or mount to back of rear seat and lose some trunk space). There are many threads on that issue, and on running RCA and power, ground, etc wires front-to-back or within doors.

your tweeter kit should come with some kind of cup that the tweeter can go into.
My tweeters had a small divot in the back of the magnet that leaves room for a screw head, so I drilled a hole in the bottom of the cup and got some small bolts and nuts and put the bolt through the cup and then trough the stock tweeter mount. twist on a few nuts and then slide the tweeter into the cup- click. solid. wire it, screw the bracket back into the door, done.

The install is done. I mounted the tweeters to the stock bracket with glue. It was easy and there's tons of romm back there for a 1" tweeter. I also mounted the crossovers in the doors. I ran the power wire through the firewall on the passenger side, i didn't want to poke through by the clutch because it's so low and water gets at it more. The wire went fairly easily through a grommet on the passenger side, got to it from the inside by removing the kick panels and a few clips holding the carpet (and maybe the knee bolster, I can't remember). I good grounding point is under the rear seat.

use hardcore velcro to stick them onto the interior of the plastic door panel
otherwise
throw them away, I guess?
gotta put them somewhere. buy speakers that work for your car, i'd say.
