did this tonight on the rear doors. The tutorial was nice, easy to do.
Only problem I had was; I had some nice components, some old reaudio 6.5". unforunetly (for this install) they have a phase plug attached to the cone, which with bass above -4 (on stock stereo) hits the speaker grill on the door.
I guess i'll have to find some other speakers.
So.
NOTE : Phase plugs mounted to a moving cone will hit the speaker grill on the door panel and make a nasty tapping sound.
