So I had the car in the garage today and thought i'd do another stereo analysis. Ha. I was actually pretty impressed today with the bass. I went inside, and the woofers, mids, or whatever they are were rattling some of the house. The only thing I noticed was that the bassy beats on some of the songs would rattle something inside the rear bumper. Has anyone else experienced this? I laid on the floor and tried to feal up under there to see if I might be able to fix it, but I could come up with nothing. The only way I can really describe the sound is as like a "flutter." Sounds kind of like somone holding a piece of paper up against a subwoofer. Kind of annoying and sounds like one of those cheap cars with a modded stereo that rattles the whole car. Thanks for the input in advance!

 

The flutter sound is coming from the 1/4 panel vents on each side. They are about 6'' square inserts with flaps to relieve pressure/vent the cabin area. If you take the little intereior trim access cover off for the passenger side tail light off you can look down and see one of the two vents.

 

Can you make it stop doing that?

 

Anything's possible; it just depends on what you want to sacrifice. I just decided to live with the stupid noise and leave it alone. You can remove them, glue them shut, try to insulate them or leave them alone. Each solution will cause different "problems".

 

Oh, great. lol. Do you have any idea what the potential consequences would be of glueing them shut?

 

Those door speakers can really buzz if you don't add a pair of capacitors as a low pass filter.
The stock stereo routes freq's to the door speakers that they cannot handle. A low pass filter will let them be mid-range speakers, and let you boost the bass to the subwoofers without that annoying distortion.

Check out the "best stereo bang for the buck" thread.

It's a simple mod and really cleans up the sound.

 

I added the capacitors sounds much better and only spent about $6.00

 

yeah, but you ain't gonna like my suggestion.

 

I am all for doing the capacitor mod, but I have only one concern. I really like a lot of bass in my music such as the thump you get from rap. What I've noticed is that most of that comes from the door speakers. Will you still get the same thump and bass levels, but just from the rear speakers?
