I have been away from the net, I looked at sending an amp to a guy with a fed ex tag, and the cost was $103 with tag insured they pack. it was only $22 somthing 5 day I pack.these speakers are much bigger and heaver, oh and the other was to california only. I do not have the cost yet, but will get on it. I will look at rail options. I will check on any comment you may have soon! see ya.
