How can speed come in "base" form

[raising_da_piggy]

you are trying to convert amphetamine salts of any sort to base, then simply dissolve it in water, then add alkali solution (e.g. sodium carbonate, sodium hydroxide etc) until it all oils out, then extract with whatever nonpolar solvent you have handy, dry over magnesium sulfate (or whatever), then remove the extra nonpolar solvent by distillation.

So if you were gonna on sulphate and wanted to carry on getting high the next day... Could you not just use amphetamine of this type as you would have a tolerance to the sulphate. ?

no, they are the same molecule and will have the same effects when ingested
