Re: Cheapest way to ship an amp. Please help.
For actual shipping charges....Fed Ex ground has been the cheapest I've found for heavy items. I shipped my amp chassis to Jeff Seal to be modded, and it cost me $17 from Denver to Houston. I can't remember the exact weight, but it was around 20-25 lbs.
Go to one of their locations and get an estimate. Also, USPS is sometime pretty reasonable. I've found UPS to be the most expensive. You can have the UPS store just pack your amp, because they do a very good job at that, and then ship it elswhere.
