The people handling our goods while in transit aren't too concerned about what is inside our box but only that they have to move and stack it as fast as they can..... Sadly, this means your box may be thrown, dropped or kicked several times before it gets to the final destination. Sometimes, enough packing just isn't enough and the package gets damaged and that's why it's always a good idea to get insurance...... If you read the small print in the terms & conditions agreement (any shipping company), it states that "the package must be able to withstand a drop of 6-8 feet."
And they won't pay out on any claim unless the packing is bullet proof. Trust me.... They won't....So here are my thoughts and tips-
*AMPS AND SPEAKERS*
-Double boxing. It's never a bad idea.
I hate when people put peanuts in the original box and slap a sticker on... If the amp/speaker is in the original box, get a bigger box to put it in. If not, get one close to the size of the amp/speaker and a bigger one. -2 inch rule. There should be atleast 2 inches of packing all the way around...Atleast. More is good when you can and is never a bad thing.
-Shake test. Don't just pour the peanuts in and call it good.
Force them down the sides tight. Close the top(don't tape it yet) and shake it. If you hear or feel any movement, add more peanuts.-Tape. I tape the box so that if the cardboard is damaged the tape will hold it together. I'm not saying wrap the entire box in tape... But don't be shy.
-MS amps need to have the power/speaker connections taken out for shipping. IMO there are no exceptions to this tip.... It's more like a RULE!!!
I'll open the floor to other tips and tricks........
