sub/rattle driving me loopy pls help

[becausegocart]

alright guys ive had it! lol

had started a system in the wifeys car

for subs i first started with 2 12" alpine type e in a alpine "type" box with a 600 watt mono block mtx amp.. sounded great flexed everyythingggg when it hit! but that was tooo heavy n weighed down car.. so i upgraded to a brand new mtx 12 jackhammer in a sealed bassworx box... was not loud enough...

finally i had bought a 12 inch jl in a ported box ( ports huuge lol...2" wide...9.5" tall ahaha... ) with a 250 watt mono block jl amp

anyways after buying the jl set up.. i had decided to dynamat what i heard rattling..


horrayyy no more rattle... or is there..


NO there has to be stuff still rattling... BUT it only seems to rattle( alot) when there is more air coming into car...so either when a window is open...or sunroof..

this unknown item does rattle when all windows closed... but no at all near as much as when open...

who can help before i go right loopy.. lol...maybe you experience the same.. or have fixed.. i hope

items dynamatted include:

-rear hatch...( all inbehind plastic cover)
-third brake light housing
-about 75% total of both inner 1/4 panels
-in behind the hatch lock down latch panel
-took out Styrofoam in spare tire section

-amp is mounted to seat so its not amp or wires vibrating as all hidden
-running strips along rear speaker housings( where hatch deck rests on)
-license plate dynamatted...but does have plate cover...will that make enough noise tho... really...lol
-third seatbelt is strapped under box.. so thats not rattling..


ps the port is facing hatch if that helps ive tried towaards hatch n facing driver...

pls help ahah

I feel your pain with all this. I'm running over 3000 watts in my G3. The reason you hear rattles with the windows down is because, well, simply put the windows in our cars mechanically kind of suck. The whole mechanism is really loose and stuff, and I don't know if there's anything we can do about it or not. Literally, the window itself is rattling against stuff inside your doors. If you find a way to fix this, let us know!

i dont believe it is the windows... i dont hear it im not new to systems and big ones in odd cars... 2 10's and 2 12's with 0g wiring in a k car ahaha...anyways i dont doubt the windows rattle in it.. im sure if i ran 3000 watts there wouldnt be much NOT vibrating ahaha.. but its FOR SUREEEE something in the back..and its when SUNROOF is open oply aswell grrrr ahaha.. i know its raised bass compression as more air is entering the vehicle...( oh forgot to add last post.. WILL NOT make this rattle if im stopped somewhere and a window is open- is only when im driving with open window) so it from the air being forced into the car and making compression... just i dont know what this massive change in air is pushing/vibrating... ughh

ok rant done lol

Hell, my 300w Infinity I have in my Aveo's hatch drives me nuts. I need to figure a way stabilize my brake light. I think that thing alone is half my rattle.

Lol i feel your pain a 300 watt jl powered to spec sucks lmaoo
best way to actually stabilize would be removal ahaha Jk If you find out a good way to do that and it removes some rattle pls share

Right now I'm working on figuring out how to upgrade my electrical, now, I'll be upgrading the system soon.....very soooooonnn.
Gonna course about 1200w continually through my Aveo, 650 to a sub and the rest to midbass, midrange and tweet tweet super tweets.
