2008 SC Subwoofer Replacement

[Monkeytx]

I just purchased a 2008 SC430 with 58K miles.  I have a subwoofer buzzing and probably needs replacement.  I found a replacement on Lexuspartsnow.com.  $450.  Does anyone have the procedure to remove the rear seats to get to the subwoofer and replace.  I don't want to pay Lexus $1200 to replace.  I added a GTA Iphone connection to the CD/Cassette stereo and it works good with stock head unit.  If any one has diagram or have replaced their subwoofer it would be helpful.
