So I did alot of research and came to a conclusion that I dont want a sub in my trunk at all! I wanted it stealth installed or hid away somewhere. Then again, I also didn't want bass that'll rock my block so I decided to go down a "premium" audio system route. On one note, this is for the cars without the pioneer upgrade as I only have the 6 speaker option. Next weekend I should get the rest of my parts in for the rest of my speakers but this is some pics from my install. I used two Tang Band subs Tang Band W69-1042J 6"x9" Subwoofer 264-837 (note: these are awkward shaped subs so they need to be custom fitted into the stock rear deck 6x9 holes! forewarned)
Along with the subs I used:
2x- 6x9 Universal MDF Spacers (too lazy to make my own and because they didn't come with templates. I am going to seal the spaces soon to make sure no sound will leak out but it is a mad tight fit)
8x- #8 1 [SUP]1/2 [/SUP]stainless steel bolts
8x - 8x Rubber washers
8x- Lock Nuts (these made the install perfect for doing by myself or else the speaker wouldve fell on my face!)
You will need to drill your own holes into the metal of course.

Here is a quick explaination on how to get to the rear deck. Credits to Cruze15 from
First, from inside the trunk take out the 2 screws that hold the third brake light in. pull down on the grey clip and then unplug the connector. Take it out now.

2nd, on each side of the car is a little plate that says AIR BAG, slightly pull the side out a bit and push the airbag plate out from the back. Take out the screw behind the plate. You might want to use a magnetic screw driver.

3rd, Pull gently on the side piece til it pops out of the 3 clips. Pull straight out btw.

4th, If the back seat is not already down then do so. Pull the plastic push clip on each side just under the latch. These clips old the rear deck to the back seat mount.

5th, lift up on the front part of the deck so you can clear the edges of the back seat mount.

6th, Pull the deck piece at an angle following the contour of the back glass.

In the end, they were completely worth it. They bump like crazy an they have an insane good response and sound reproduction. I can hear/feel it outside of the vehicle if i turn it up...and that isn't even blasting them. So really, they turned out to be the perfect sound I was looking for. I don't ever really have to turn them down as they aren't boomy as ported subs are. I installed these IB by the way IMO. Next week i'm installing a 4 channel amp, two sets of kenwood component speakers, and dynamating the doors and rear deck. Yes, I am custom mounting tweeters in the rear doors! I will do a write up when I'm done! Feel free to ask any questions I hope I filled in some gaps other posts didn't.

Have to say the Cruze is the one and only vehicle that I have owned that has small rear door speakers. Wonder why they did this, when you get much higher sound quality from the package tray and already laid out for this.

04 Cavalier had rear deck speakers, cheap single cone speakers with a magnet about the size of a wedding ring. Replaced those with Blaupunkt overdrive 6 by 9 full range speakers, wow, what a difference. But also installed an auxiliary amplifier to convert the radio from a CD toaster to a CD player. Just used the fadder to kill the front door speakers, my feet don't have ears anyway and were causing acoustical phase distortion.

So what did you do with your rear door speakers? Disconnect them? Sure can't parallel additional speakers, would overload the car radios amplifier. Stereo infers two sound systems where the music is recorded with two microphones to produce a lot more fullness to the sound. Adding additional speaker with the same identical signals only acts to degrade the quality of the sound. Ha, and contrary to so-called purist, do love the ping-pong effect.

Did add rear speakers to my home system for sound surround, but entirely different signals, makes my relatively small listening area sound like a concert hall. In my Cruze, haven't play with it yet, just kill the rear door speakers, notice a degradation in sound quality with those turned up. Certainly wasn't designed by a professional. A marketing guy is more like it.

Rare for me to have the rear seats down, only when I am hauling something, but a cure for this also. Radio has an on-off switch.

Also a L-R and R-L circuit that by increasing the negative levels gives the effective distance a lot more width when speakers have to be mounted closer together, like in a car. Add this and sound surround would be nice, but the main speakers have to be in the front. Impractical and would require some really major modifications, like getting rid of the air bags.

Ha, in my airplane all I got was a 4" speaker, but if you want to stay alive, far better off to listen to ATC than to music.

Best sound in a vehicle is to wear noise canceling head phones, but is illegal, but say nothing about adding a 2,000 watt system to your vehicle. Can also get a driver's license if you are stone deaf, so will leave this to you to figure out. I could, if I was smoking crack like our law makers do.
