I've looked at the specs on ED's website and from what I read it should be a suitable subwoofer for a stock replacement.

It's infinite baffle compatible and looks to take a decent amount of power which of course would mean an aftermarket amp but I'm not afraid of doing that. Has anyone else done this or tried it in our TL yet? I searched for e3.8 in this sub-forum but came up with bupkiss. Here are the specs for the sub. The only thing I see having to do is modify the hole on the bottom to make it larger for the magnet to drop through.

Also on the hole/install.. Would this void any kind of warranty on the car?
