Ok couple quick questions that I know you guys will have answers for. My rearview mirror rattles like crazy when my subs bump and it makes a god awful sound that just ruins everything, any way to stop this? or attach it better? And my next question is my box is sliding towards the back when i drive and is sitting on a piece of carpet, is there anything i can do to hold the box in place without bolting it down? i know you guys have answers for this youve got answers for everything thanks
