So I think we have some obvious choices here. Upfront, replace the 3 way setup in the doors with a high quality 3 way component set. I'm thinking focal or dynaudio - but insert your favorite brand. We'll need an amplifier to run these and depending on the crossover in the 3 way setup, we may be able to bi-amp the component set. That would be my first choice with a quality amplifier around 100x4rms.
As for the subs, I would scrap the current configuration completely. The left rear corner of the trunk has a lot of room to do a single 12" sub in a fiberglass enclosure. This maintains the most amount of trunk space, but would exclude putting a golf bag back there. For the golfer, I'm thinking a single rear firing 10 or 12" sub. I'm not a golfer, so off to the corner for me. To power this sub, I'll match it up with the correct sized amplifier, say a JL Audio 500/1. I would probably build up the trunk floor just enough to hold the amps and crossovers - with panels to hide them.
Example of side mounted sub - this is from a G35 coupe:
To interface with the factory radio, I'm thinking JL Audio Cleansweep or equiv.
Now the wild card is what do with the center speaker and the rear speakers. My first thought is to upgrade the driver, but leave it powered by the Bose amplifier. These are the areas I'm most unsure of right now.
So this is meant to be brainstorming.. Feel free to comment on what I posted or just lay out the upgrades you were planning.
