To start have 10mm and 12mm sockets screwdriver and about 30min of your time…

Automotive exterior Vehicle Bumper Car Rim
Start in the rear its easiest.. untighten the top two hooks for the mesh net (not the bottom ones as they are not holding the plastic into place) then pull out from the sides and then up to get it out.

These are pics of the left side and it’s the same on both sides… Remove the screw holding the left and right panel in place the panel you just removed was covering up.

The pic shows the plastic surround the covers where the back seats latch into. All you do is pull it towards you as shown.

Here and (lift up the spare tire cover and remove the two screws is holding down the SUB panel) start popping the panel out and you will see the bolts shown holding the top panel into place. HENCE if you are not doing my ADD TWEETER DIY then please disregard taking top panel out and its bolts.

On the driver side (DS) corner of the back seat lift up the fabric as shown an use the 12MM to take the bolt off.

As seen to the far left the is a metal shaft that held the opposite end of the set into place so when the bolt is off pull the seat to the front of the car on an angle and pull it away from the shaft and that’s done. In this pic you also see one of two bolts that hold the bottom seat down also takes the 12MM to get it. The PS one you can get by letting the top seat fold down and there is enough space to get it without taking the top seat out.

Once the two bolts are out then lift up on the front of the seat and it will pop out as seen here the white colored female type holder as there is one on each side. To the top of the pic you can see a screw holding down the panel for DS rear speaker panel.

Go to DS front door lift the center plastic peace as it is holding down the panel for DS rear speaker panel and after that pop it out.

Then you will see the rear speaker and the sub has been exposed when you removed its cover during this process. All you do is unscrew it and place your own 6.5 or whatever you want as there is a lot of space…UMMM MAKE A GOOD DRUG CAR WITH ALL THIS INNER WALL SPACE YOU WILL SEE WHAT I MEAN!!!:cool2:

So you didn't replace or add amp, just replace the rear subwoofer?? Was it worth it?? Add a good bit of bass??

I like the sound system as is already, it sounds great, just lacking a little bit on the bass. I really want the 12" that goes into the spare wheel space, but I'd rather replace the stock one and not have to run a separate amp if that's a good improvement.

Well 99.99999999% sure any sub used aside from this one you will have to use a new AMP you can keep the old one an just add one for your sub. I wish there was a way to use the stock one but the stats of any aftermarket sub is worlds better than this 2ohm 20-40w max oem one...
also with many aftermarket speakers they are 4ohm (not subs) so with any improvment to the sound with a 4ohm speaker you will have to replace the AMP as it will burn out or die or who knows but its a deticated 2ohm system using 4ohm can be negitive in some way.

I picked my replacment Sub and it will be Rockford Fosgate P2D4-8 8" P2 Dual 4-Ohm Subwoofer as it only requires .2-.3 qft for the enclosure and give or take (more like take away) with the dimentions of our oem one we are at .479

Instead of posting a separate thread i will just high jack yours. Here is a couple terrible quality pix from my --front door component speaker upgrade and sub woofer/box and amp install. If you have any questions on what to expect or tips on doing your own install just PM me I will gladly assist you. Here is a few pics - I did not write up a DIY, because there already is one that was very similar on veloster.org.

Step one-Remove the butyl surround plastic retainer.

Step 2- "this will destroy your stock speaker" rip out the cone and then use diagonal clippers to trim the basket away making room for replacement speaker.

I was going to just throw in a replacement 8 inch... as you can see that was not sufficient. Now I get absolutely ridiculous sound with almost zero vibration noise inside and out, the small vibrations can be fixed with a piece of foam tape.

trunk for what...spare tire?... the wife brings home groceries in the other car. This trunk is for subs. LOL. I will say that I already blew up one of the speakers :( damn "woofer cooker". gotta throw down for something that can handle more Power. Also, the picture is deceiving I still have about a good 1-2 feet of trunk space left but its hard to tell from the pic.
