Ok, so my current set up in my 99 civic ex coupe is..... 2 memphis 6.5"s in the bottom of the doors, 2 memphis 6x9's in the rear dash, an alpine 12" sub in the trunk and a kenwood amp feeding from the sub... Also, the kid that had the car before me bought 2 tweeters (one for each door by the window) but never hooked them up.. I have a Sony xplod CDX-MP70 head unit and here is the guide to the wiring:
- blue with white stripe = amp trigger
- white = left front (+)
- white with black stripe = left front (-)
- gray = right front (+)
- gray with black stripe = right front (-)
- green = left rear (+)
- green with black stripe = left rear (-)
- purple = right rear (+)
- purple with black stripe = right rear (-)
- yellow = hot always
- red = hot when key switch is on
- light blue = attenuate input (cell phone, etc.)
- blue = antenna trigger
- black = ground

Now how about would i go hooking up those tweeters?!

 

when you put in the front door speakers. There should be 2 wires that go from those sets of wires up to the tweeter.

 

I'm curious as to where you mount these, my 98 sedan doesn't come with mounting locations, is there an A-pillar thing you can buy?

 

Good to know, I've got two tweeters not hooked up to anything also.

You can really put them wherever you want.

 

they mount where your mirror connects to the car. THere is a little plastic triangle on each side that they would mount into it they were stock but im not sure if they will fit aftermarket ones unless you mount them to the outside of them
