Re: Amp rack patch panel - front or rear & why
Assuming your amplifiers normally ride right side up:
1. Cut a 2x4 to the appropriate length.
2. Use sticky-backed velcro on each end of the 2x4.
3. Use the rest of the 2x4 as a lever to lift the back of your amplifiers so you can wedge the 2x4 between the amplifier's rear corners and the bottom of the rack.
Normally, the weight of the amplifiers will be adequate to hold the 2x4 in place, but for the odd times that it gets flipped and whatever, the velcro will help hold it in place.
The 2x4 should be cut to the full length of the space you are trying to span so the velcro is getting smashed as tightly as possible when the amps are just hanging out. There should be no wiggle and wobble at the back of the amp when the rack is rolled around.
