Thanks for the replys guys. That info helps a lot.
Assuming I start with front components (the Jan 08 Car Audio mag p.90 actually recommends starting with Focal speakers for the Civic) what would be the better way for me to wire them up?
Would using the stock wiring for both the doors and tweeters be a good option? Or should I tie the component crossover into the door wiring and then run new wire to the door speaker and tweeter? I am curious since using the new component crossovers would effectivly bypass two of the amp channels and maybe some signal if the door isn't getting a full range.
I can see how running your own wire from an amp would bypass a lot of these problems and would probably be the way to go when its upgraded.
Thanks again.
Edit: I found this issue discussed here.
Crossovers...
