Hey folks.This post really only applies to people NOT using freeair subs as the port will be in back if your drivers.I have a pretty nice system in my car but my subs(2 12's in a sealed box)weren't hitting as hard as they should.The trunk,deck and rear seat are way too airtight so I removed the 6x9's to allow some more bass to escape and it was a huge difference.I had to turn my amp gain down to around halfway versus almost cranked!Dont get me wrong,the bass pounded very good before and would be adequate for probably most people.To my ears it just sounded too "contained".The bass hit so much harder w/o the 6x9's and actually sounded a lot more refined and accurate.Unfortunately,my only option is to cut a hole in the sheetmetal as I do not want to remove the 6x9's.I'm not talking about cutting a manhole cover out of my deck,probably a 6"x12" hole.I will cover it with wire mesh to prevent the carpet from sagging.There really is not that much open flat area in the sheetmetal to cut but there is a nice spot in front of the third brakelight.I know a lot of you don't want to hack your car but if you do it carefully it will be invisible from the top and with straight cutting,nice and clean on the underside.A little dremel work will yield smooth edges and rounded corners.Touch it up with a little grey paint and you're good to go.It may even look pretty stock.There shouldn't be any structural weakening either.If you are happy with your bass then rock on,but if not,listen to your stereo with the 6x9's removed.It takes all of 10 min to take them out(push grill clips up from INSIDE of trunk with pliers or something then well..... you know what to do...)It makes a very significant difference.Post your thoughts if you try this!Later...

right after i swapped out my front speakers i just yanked out the 6x9's. they didn't add much for rear fill and what they did add was crap anyways. with a nice set of components up front i don't think you need anything else except for subs. i'm thinking eventually adding another set of comps to the front so its a little bit louder. or maybe a pair of 8's or something. for now it sounds good tho.

I took the material out from under the carpet in the rear deack and took every thing out behind the rear seat and kept the arm rest down. That worked for me but I will be putting a hole in the rear deck soon.

i took all the stuff out of the rear deck today. i am just left with the metal now. i don't have subs in there yet, and if victor would send me my amp then i would have something. but i 'll have to wait i guess. i'm going the rear deck box route, whever it is i get enough free time to work on it.

if you are cutting the sheet metal of the rear deck, make sure you dynomat the rest of the metal to avoid the rattle, in my case a port through box works better, just like the one that Steve has on his Impala, this way there is no need to delete the 6x9's, I would just replace them with a set of components or 8" mids.

If you install 8" you should go with mid-bass drivers and set-up the system as a bandpass. Basically making the entire car one big speaker with the sound stage in front and low mid bass in rear with the dubs. Just a thought.

ANother note: if you have speakers in the trunk that are not in a bandpass config with the port going through the rear but instead share the trunk air space, this will affect any speaker you put in the rear deck causing them to want to sync the movement with the subs. This will cause the back speakers to sound bad cus they want to move on their own. Most people who do this put very little powered speakers back there just to get the rear fill. Either enlose the speakers in the rear deck or move them to the doors,etc.

good call on that twig, you'll just blow your rear speakers if they are not in there own enclosure. with all the bass in the trunk i don't think you would hear them anyways.

Ive been wondering about doing this for a while. I also have 2 12"'s in my trunk in a sealed enclosure. They sound OK, but they should be louder. I will definitly try removing my 6x9's as they are practically useless now anyways.

Which way do you ppl have your sub box facing? I have mine facing towards the back of the car, because the subs give a sort of "muffled" sound when faced towards the seat.
