How to put wires from doors to A pillars (tweeter install) without disassembling fenders? Any ideas? 2000 EK sedan

 

Why not just splice into the door speakers?

 

Run wire up from footwell in gap between frame and dashboard? There's enough space. Plus, that's how Honda does it to run wiring to the OEM overhead centre tweeters ... wiring comes through there and along A-pillar to overhead (on a 5G Civic).

 

The tweeters in the door NEXT TO the A-pillars or are you mounting tweeters IN the A-pillar?
Next to-post #2. In-post #3.

 

are you putting the tweeters onto the actual a pillar trim panel?

why not get the oem ones that mount where the side mirror cover goes. comes on the EX models.

but anyhow. you can tap into the door speaker and fish it through the oem loom that goes from door into under the dash.

or splice into the speaker wire from behind the deck and run it under the dash up to the a pillar

 

OP has a sedan, so those door mirror cover tweeters are difficult to find and expensive. Coupe/hatch ones are dirt cheap.
