... would a dedicated 20amp circuit be the way to go wanted to get 120 volts all the time and get away from voltage dips I get any where from 119v to 105v in the summertime is this hard on the amp?

Are you in the US? If so, 105VAC is definitely considered low voltage. I would check your voltage at the service entrance and if it really measures that low, you should notify your electric utility.

A dedicated line can help with reducing voltage drop, and of course it has other advantages, too. But it sounds like you have other problems as well.
