I purchased the dash piece for a civic with nav. It gives you a double din hole. You transfer the heater controls. DONE.
The "factory" dash trim was 40.00$

 

i looked into this too having a 06 ex/nav........the only thing i can do is buy that little adapter piece that converts wire to RCA {20 bucks i think} and run a 4 channel amp.................but my problem is where to put the front tweets

 

^ i had the same problem. However, look into fabricating you kick panels to hold tweeters.

 

In the "perfect world" the tweets are supposed to go as close to the mids as possable. I'm mounting mine under, or most likely in, the grills in the corner of the dash. The grills are 3.00 ea. so get a couple and play with em. Not much room under there for BIG tweets.

 

Where can you get the grills for $3 each as I will be putting some new tweeters in there soon and I may need to modify them (Infinity Kappa's), unless someone has a success story they want to share?

 

i think i'm going to cut holes in front of the door handles.

 

get that headunit it looks so damn sexy!!

 

I got mine from the dealer.....!
