Well the project kind of stalled at the moment as we ended up buying a TSX.
I have some Pioneer TS or GS 3-way speakers in the rear 6x9" spots.

They are blue mica like material with rubber surrounds. They have a depth of 2 5/16" which is the max depth the coupe can use with the stock trunk torsion springs in place. They sound really good from the factory head unit

Else the rest are stock, but I think the max stock depth for the door speakers is 2" I was planning to purchase some Blaupunkt Overdrive speakers for the doors b/c of their slim profile and power handling.

I haven't yet picked a head unit but at this time I'm running a Kenwood satellite radio system via hardwired FM modulator on the OE radio. So I planned to upgrade to a Kenwood headunit to use my current tuner and cables to keep my satellite radio setup.

I ended up getting a company car so my Accord doesn't get driven much so upgrading the radio hasn't been a major goal at this time. I'm currently in the process of moving so maybe I'll get to the car again this summer.
