Need help with speaker problem

[hiroprotagonist2005]

have the 3.5 pkg with the bose system, i think some boxes in my truck knocked loose some wires (hopefully nothing worse) in my rear right speaker causing a rattling/static sound especially with songs with heavy bass.

any suggestions on what it might be? i've already taken off the carpeting around the speakers through the trunk and checked the wires; everything looks good/connected so i dont see anything obvious that would be causing the problem.

i'd rather fix it real quick than disconnect the speaker but it might come down to it.

ALSO: anyone know if you can access the speakers through the inside of the car? taking off the speaker cover from behind the passenger headrest?

Check the amplifier for that speaker.

Sounds like a blown speaker to me, especially if you only hear the rattle on heavy bass. Troubleshoot...turn the bass 100% off, fade/balance to each speaker and see what the difference in sound is like. If none, crank the bass, dead the treble, and do the same thing. My guess is a separated/torn cone.
