I copied this from the acura forum... see if this will work. You'll need a 10mm socket with a ratchet extension to reach the bolts beneath the seat bottom. Ready? If you're facing the back window, there is a bolt at the right side of the armrest (between the seat back and seat bottom) Spread the seat bottom and back with your hand and you'll see it bolted to the metal floor of your TL. That bolt is holding a little metal arm - remove that bolt. Now pull up on the front parts of the seat bottom and pop the 2 clips that are holding the seat bottom (1 clip in front of left & right side). IMPORTANT: Make sure you remove the bottom of the seat before the back or you'll scratch your leather with the metal parts of the seat back!!! Pull the seat bottom out of the car and remove the 3 remaining 10mm bolts that are holding the seat back to the floor. See those 2 big metal tabs on the bottom? Careful you don't scratch your paint when you take that out of the TL. Now take the seat belts and swing them around so that they're behind the seat back. Push up on the whole seat back - towards the ceiling - to remove the 4 large clips that are holding the seat back to the rear deck. This is the hardest part! Just take your time! Pull the back out of the car and you'll see your trunk and your sub amp behind the right side seat. Let me know if you need anything else buddy!!!
