Quieter after bolt down

[Guest KyleCannon]

After I put brackets from the sub box to the chassis of the trunk in my car all of a sudden my bass is twice is quiet. Could it be that the box isn't vibrating in my trunk as much that creates the sound or can my grounds of been screwed up when moving my stuff around? I don't hear any whining coming from my subs or anything at all and everything sounds just as "clean" as it did before but I'm trying to figure out what may have caused this before i pull my back seat out of my car again in 100 degree weather. Any ideas?

EDIT: Other thing i forgot to add is I have a crap load of Dynamat back there and always have had it so nothing has changed except the sound...

This would be my guess, but you can try to ground the amp(s) somewhere else also.

Yeah i just find it weird that it's doing this considering i have a TON of dynamat in the back and it was always loud..
