(since removing/unplugging the center channel is free: do this too).

If you were to do that single thing but a touch fancier, move that coax to separates/components with passive crossover and the OEM sail panels to house the tweeter.

Either way, with the door card off dampen the door before reassembly.

Those front door speakers are the single weakest area in the car.

P.S. the summary from the million threads on audio for 'proper' upgrade path is:

1) remove front center speaker

2) replace door speakers with coax* and dampen doors
2a) *component

3) replace rear fill w/passive coax

4) replace amp
4a) replace amp/processor
4b) replace amp/processor/run active crossover not passive

5) replace subs
5a) remove subs and use trunk sub instead
5b) bandpass filter underseat subs and use trunk sub for low fill
