My car didn't come with the door speakers - I looked into obtaining replacement door skins, speaker enclosures, running the wiring...and it is beyond what I'm willing to invest (particularly for speakers that would be aimed at my legs!).
I've seen mention of custom fiberglass enclosures - apparently some smaller volume ones work - in the passenger footwell, and...I'm not thrilled by this solution either.
And I have a pair of Harvey Peck's rear shelf speakers that I haven't yet installed.
But...has anyone ever thought about mounting a sub, or perhaps full-range speakers...in the lower console? OK, you'd lose the tray (and in my case the CD holder), but it seems like a reasonable tradeoff for what would probably be good speaker placement. I know you can easily delete the entire lower console, so there's nothing critical in there.
So what do folks think about turning that space into a speaker enclosure?
