I noticed some rattling sound near the trunk when playing music. And also the volume or power of the sound isnt as loud as before. Could it be that the subwoofer went out or ripped or would it be that the amplified isnt working at full capacity?
Trunk rattle happens in these cars depending on year but you could definitely attempt to take the rear deck lid off to make a better assessment. You'll have to remove the back seats first and the trunk deck liner. It's also easy to add additional asphalt based sound deadener
