Choosing of converter help
best bet is to call a pro and ask them to make one specific to your combo and intended us in my opinion...
i've been using dynamic and have very happy with them..
also give ultimate a call.. hey are very good as well...
the right converter will make or break your combo.. don't cheap out in that dept.
make sure you are 100% honest and accurate about your combo and intended usage if not chances are you wont be happy...
