it wasn't difficult at all for me. I believe there were 2 Philips under the arm rest, 2 torx under the cup holders for the rear passengers, and 1 or 2 either Philips or torx under the front cup holders. then you sort of finagle/shimmy/wiggle it away from the front portion with the gear and trans levers
I guess the only difficult thing was trying to figure out how the connection disconnected. every time I come across one, in any car, I wonder if im going to snap a tab trying to disconnect them. and I never really know if a separate locking slide is present. very small flat head screw drivers help, like glasses repair kit size
then once the console is off there are a couple one-way sort of spikey caps holding the speaker and amp assembly to the console housing, which I destroyed whilst removing. I have tons of fasteners and such in my garage so I should be able to fasten it back together somehow. It attaches via 2 plastic nubs so I could either run a screw with some thick spacer washers or thread the outside and run a nut down on it. sorry I don't have any pics right now, maybe i'll snap some when I get home tonight
as for the sub speaker itself, I shied away from the $90 replacement from quadratec after reading the reviews, and I wasn't about to pay OEM dealer prices if it's even still available. I found one on amazon that ppl have been using but have had to do some custom cutting and whatnot, about $17
im not looking for the greatest audio ever, but I do need a little bass back. I really don't plan on doing anything special with the sound system, I don't even want a different head unit. at some point i'll dig deep in my basement junk pile and find all the cds I used to have from the late 90's so I can at least listen to something without static or commercials.
