GS Mounting Amp on Back Seat
How are people doing this? I was going to mount my amp against the back side of the rear seat, but there's these cross beams there, and nothing to drill into. Can anyone help me out with this? Any Suggestions?

Cut a piece of MDF or plywood about 2-3 inches larger on all sides than the amp. Cover it in trunk color matching carpet, then attach it to the cross beams securly. Then mount the amp to the board.

It can be difficult, depending on what size you cut your amp rack (MDF board) to. I bolted mine thru the rear deck overhang in two places at the top, left and right, and supported it in the middle by using a nice large bolt/nut (with rubber spacers) thru the center hole of the middle support brace. Make sure whatever you do, you use large washers on both sides of any screws/bolts to de-stress each mounting point. This is necessary because as the car flexes, the holes in the MDF/plywood will enlarge, and you don't want anything pulling out later on. Liberal use of dense rubber spacers at contact points also helps to keep everything squeak-free as the car flexes.

If you go to the Member Galleries section under "gallery" here on ClubLexus, search for "engin_ear" and up will come some pics of my install. They don't show the amp rack mounting, though, but may give u a bit more of an idea.
There's another picture of Dex's install at www.digitalsimple.com under 'sound better'. It has a picture of his amp rack and the braces...
You have to play it by ear - see what you have, experiment with sheets of cardboard if necessary, to see how it will fit in. Unfortunately u have to take out back seats to do this...

The sub is 8ohm and the max RMS rating is 100 watts, so I would recommend an amp that puts out about 200 watts RMS into a 4ohm mono load. You will have to make a mounting ring for this sub (since the stock ring is actually part of the factory sub) but that is pretty simple.
Good luck!

Can someone tell me an easy way to get the rear seat out? I am trying to get the factory sub out of there but can't get the seat out. I pulled, tuged, pushed (from the bottom), hit a couple of times, cursed at it for a good 10 minutes, but it's still stuck. Is there a trick to taking it out?

No trick, it's just brute force. You'll need to pull straight up from the front of the bottom seat cushion on *each* side (at the center of each seat position) - that's where the (2) clips are that hold it in place. Each clip requires quite a bit of pressure to unsnap it, and if you don't pull where the clip is, you'll prob ruin the seat, and still not get it loose. Using a jerking motion usually helps. If you can't get it loose, try using a lever wedged deep underneath the seat, but be careful not to ruin the seat cushion.
Usually, if mine is stuck, I put one hand on either side of the clip and pull up hard.
