I found an old roll of 1½ foam I used to re upolster my weight bench so I said hey that would be a comfy bed for my amps lol. got tired of worrying about them breaking so I cut it to fit my lock box and then cut 10 slices down the foam with a hobby knife(I had 20 amps so you can cut for your total quantity). All that's left to do now is tuck them in and tell them goodnight lol. I posted this so maybe it'll be some help to you guys who are worried about breaking your amps like I was. Enjoy!
