So i finally finished my kickpanels for my alpine type X 6.5" mids.
As i was doing some initial tuning i noticed a problem.
The left side speaker/kickpanel makes a weird noise. The noise is hard to describe, but it kinda sounds like a subwoofer that has a air leak, or a speaker with a messed up voice coil.
The sound is not popping/crackling etc. Not sure if anyone knows what i am talking about, as its hard to describe in typing.
The right side kickpanel/speaker sounds fine. I tried both speakers in the left side pod and they both make that same sound, so its not a speaker issue. I ve taken the pod out and held it in my hands (incase it was rattling against the car), and tested..same thing.
Ive polyfilled, i cut a hole in the back etc.
The sound only start to occur at higher volume (22+/35).
Any idea what could be causing this noise, it is audible and annoying??????
Also the left pod is bigger since it had to be. I just added more fiberglass to the inside tonight, but could only do so much since its hard to get inside the pod.
