passive radiator on rear deck

I spent a few hours searching and couldn't find anything. Has anyone done this? I have a 1996 Ford Contour GL 2.0 The rear speakers are in the doors and i got 2 12" Kicker CVR's in the trunk. I was looking for a little better sound so i thought about "porting" my trunk but then i thought hmmmm maybe a passive radiator would work well too? Any thoughts?Ohm's law ain't got **** on me!

Not gonna work. A passive radiator is the same thing, and performs the same function as does a port... If the PR or the port is not in the same airspace as is the driver (and I mean SHARING THE SAME SEALED CONTAINER) neither of them will do anything. A port, as in a tuned device, between the trunk and the cabin will not work. If the port actually enters the box in which the driver itself is housed, and THEN put through the rear deck, THEN you can get some result... possibly good, possibly bad. Putting a PR in the rear deck without somehow following the same methodology, will likely only be destructive to your sound, and/or just plain sound like crap.

I have a 96 Ford Contour Gl with 2 12" Kicker CVR's in a sealed box in my trunk with 200watts rms @ 2 ohms going to them. My rear seats don't fold down and all 4 of my speakers are in the doors so my rear deck lid has nothing there it's just carpet, sound deadening and sheet metal. The weatherstripping on my trunk lid vibrates heavily but doesn't vibrate at all when my trunk is open. So my theory is that because of the sound pressure my subs are putting out and the fact that my trunk is sealed pretty well makes that vibrate. NOW if i cut a massive hole or 2 8" or 6X9 holes with speaker grills over them. With those holes my trunk would be sharing MORE of the same air as my cabin so i would probably get less vibrations in my trunk and maybe more in my cabin. In my theory. :p Has anybody ever actually done this?Ohm's law ain't got **** on me!

Sure.  Sometimes it works, most times it doesn't.  It turns your trunk into a mis-tuned 4th order bandpass enclosure and unless you get really lucky you end up with a booming terrible sounding setup.Support the12volt.com

What would you recommend to help my trunk stop being so loud?Ohm's law ain't got **** on me!

Stop your trunk from being so loud?  You do that by using the volume control and turn it down.  But if what you mean is you want to stop the vibrations, there are plenty of ways to treat the trunk to help stop that.  But if you want a loud system, then it's going to be loud in your trunk....Support the12volt.com

haha yeah what i meant was to stop the vibrations, turning your trunk into a speaker would be interesting though, lol. What do you recommend to help keep vibrations down? dynamat? Thanks for the help by the way. Ohm's law ain't got **** on me!

Dynamat or one of the many similar products out there is a good place to start.  There are trunk kits available that will help.  If you want to get serious a good shop in your area can do the job with ease.Support the12volt.com

yeah so that was one of the funniest threads ive read in a great while.   thanks DYohn for a good laugh.
