Them damn packing peanuts, arent they annoying? Well this is how annoying they can be. I purchased a used Mirage sub a year ago off ebay, and was very happy with my purchase(somebody selling for a friend didnt know how to list it and I got it for $52 and thats with shipping included!), anyhow I had noticed a couple times at low volume there was a somekind of rattle coming from it. Very annoying to someone who hears everything! So I just dismissed it and turned it up so I couldnt here it:D, like any annoyed listener might. Well yesterday while watching Nascar it was there again, so after the race I decided to venture inward and to my delight I found the problem, Packing Peanuts had come in through the port on the back of the sub during shipping! They were lodged everywhere inside, thus with the thumping of the sub they would cause the annoying little rattle I was hearing. Ive been listening all day and no more rattles. So everyone BEWARE of the packing peanuts!
