bluemsp and terbow,
Be sure to put some double sided stick tape on the rear license plate, if you haven't already done so. Your gonna need to. Also make sure to use the supplied foam gaskets on the mounting surface. It makes a much better seal than without it, trust me, I tried it both ways. Sub box is almost completely airtight. I did the ole trick of pushing in the sub and seeing if it comes back out slowly and it did come out pretty slowly. Also if you haven't already done so, you might think about removing the plastic 6x9 plates that cover the factory openings in the rear dash. It increases the bass output with the rear seatbacks in the upright position. Here's a pic of what they look like:

Also forgot to mention that all the pictures that I've seen of the Stage 2 sub, show it with both spring posts and clip style connections. But mine came with only the spring posts. I dunno if this was just specific to my sub, or if they've deleted the use of the clip style connections because of clearance issues. But you can either do what I did and solder two wires to the factory connectors or just cut the connectors and remove some of the insulation to expose the bare wires. I soldered two wires because I've never liked the idea of cutting the factory wiring.

Yeah it's real simple. I just edited that post that you just replied to and added a pic of the plastic 6x9 plates.

Pull down both rear seatbacks and you will see 5 plastic doohickeys holding the rear dash. They are made of two pieces. Pull the center part out with your nail and then the whole little doohickey comes out. Do this to all five. Then all you need to do is grab the rear dash from where the doohickeys go through it and push up on the rear dash. It is also held down with some clips hidden on the other side of the dash, so some "friendly persuasion" might be needed in order to get these clips to let go. Be very careful not to pull up on the rear dash too hard as you may end up scratching your rear tint(if you have tint) when the rear dash finally does come loose. Once its loose, just lift the rear dash up and towards you and set it down between you and the where the rear dash was before. You will then easily see the plates and all you need is a phillips screwdriver to remove the four screws holding each one down. I suggest you screw the screws back down in the factory holes(tightly) as to not lose these screws as they may come in handy if sometime down the line you wish to mount some 6x9's or use the plastic plates to cut some holes for some 6.5" or 5.25" inch speakers/components back there. This way you already have screws that you know will fit properly. The factory connections for the 6x9's are still there and are connected to the plastic plates. You'll need to disconnect these before the plates will come loose. Also I suggest that you tie down these connections as to not have them flapping around and possibly making an annoying rattling sound when you hit a bump or when you turn the bass up. While the rear dash is out it might not be a bad idea to stuff some insulation down there to elliminate some of the rattlling between the sub box and vehicle chassis/body and between the vehicle chassis/body and the rear dash. Better to do it right the first time, cause I guarantee if you don't do this, you will have annoying rattles. If any of this is unclear please just ask me to clarify, it's absloutely not a problem. I'm just trying to help. Unfortunately I can't go out to the car right now and take pictures of some of this because my fianc has the car and she's at work.

Dynamat would be best but you would have to remove the sub box so that you could place the dynamat between the the box and the chassis. I just used this foam that looked like carpet padding. It's like made up of different color pieces of foam glued together. I'm pretty sure you've seen this before. It worked for me. Stuff just enough in there so that it creates pressure between the sub and the chassis/body so that they don't rattle against each other. Just keep in mind that if you stuff too much in there you might defeat the purpose of removing the plastic 6x9 plates in the first place. I just pushed down on the sub box through the 6x9 openings in strategic places and listened for what sections would cause the rattling sound to go away and then I placed padding in those areas. I don't know where to find it as I got it from a roll that I found at my parents house that my brother used to use back in the day when he was into car audio. It's a little ghetto, but it works for me and as long as you can't see it, what's the harm. On the top part, just cut a piece that is about the shape of the rear dash and place between the rear dash and the vehicle chassis/body. Then reinstall the rear dash with the five little doohickeys. It's that simple. I don't think polyfill would work since it's got to create pressure and polyfill is too soft and fluffy.

subscribing to this thread... buddy of mine has a "supposed" dead 8" W0 - hopefully 4ohm. Wish I could hit up on the Rockford, but if that JL works, then I'll finally get my boom back. Ya know, the 8ohm wouldn't kill the sub. Thats for sure. I'm very very sure the gain on our amps must be put way over the limit... I hope when the replacement sub comes in for me this week they'll figure out what the hell is goin on!

I didn't replace my Kenwood sub because it blew a voice coil. In fact my Kenwood sub still works, but the rubber surrround literally pulled itself apart from the cone. The gain on my amp is set to like the 1:30 position on a clock, so it's fine where it's at. The reason why the cone on my sub seperated from the rubber surround is because it was over extended.
One day I get in the car(it's my fiance's daily driver) and notice that the bass is really bumping at a very low volume, so I turn it up only to hear this awful rattling noise coming from the 8 inch sub. I check the settings and notice that they are all messed up. The bass was set to +8, the door speakers are running straight through, no low pass on them and the non fading volume is also cranked up. Oh yeah it was slamming, at the cost of an over extended sub. I asked her why all the settings are all messed up and she says that she was messing with them because she wanted more bass and couldn't figure out how to put it back to the way it was. I was really pissed at her and told her not to mess with the settings again. It wasn't until after I spent four days researching subs on the internet that my fiance finally spills the beans about her dumb ass friend and what really happend to the sub. After work, my fiance and her male coworker went to Walmart. He decided to stay in the car and wait for her to grab what she needed and just listen to the stereo since he "has a Kenwood stereo almost like this one". Oh but noooooo he couldn't just sit there and enjoy the wonderful sounds of the Kenwood stereo that I had spent 2 hours fine tuning to my and my fiance's personal taste in music. No he felt the need to **** with all, and I mean all the settings on the radio, including the sine waves and frequency cutoffs for the door speakers. When my fiance got back in the car she found him messing with all the settings and told him that he shouldn't have done that because her fiance(me) was gonna get pissed. He then goes on to say, "but look it sounds so much better now, the two(2) 8 inch subs hit so much harder now." Oh yeah the one(1) 8 inch sub was boomin' alright. ******* dumb ass. When I found out about this I told her not to ever cover for someone elses dumb ass mistakes. I told her don't you realize that the very dumb ass that you were covering for was the same person who is responsible for blowing your sub. When I told her that, she then started to get pissed at her friend. I told her that either she tells him that he owes her a new sub or I will. Which is it gonna be? So she tells him and he starts to get all defensive stating that what he did to the settings couldn't have possibly blown the sub(s). My fiance then tells him that if he doesn't want to be held responsible for screwing up other people's s*** then he shouldn't be messing with them in the first place. She then tells him, "oh by the way my car only has (1) 8 inch sub not (2). He took off pissed off and they didn't speak for like a week until he apologized for messing with the settings, but he still doesn't feel like the changes he made in settings could've blown the subs. Hmm let me see, bass used to be set to 0 and now its on +8, but that couldn't possibly be the reason for the blown 8 inch sub, huh!!!
The Golden Rule:
Never **** With Another Man's Woman.
Never **** With Another Man's Car.
And Never **** With Another Man's Stereo.
As I see it, he ****** with two out of three. I still haven't ran into him, but when I do he and I will have some very interesting words.(gun)
