My wayward thinking was that going from doubled up 12ga to a short single piece of single 12ga through the surge protector would be restricting.
The important thing to remember is that a piece of 12 ga wire has twice the resistance of an equal length of doubled-up 12 ga wire (assuming [big assumption sometimes] that the connections are essentially zero ohms).
Let's say you crimp or solder two 12 ga wires together and add a six inch tail of 12 ga wire.
The resistance that tail would add to your wire run would be the same as one foot of doubled-up 12 ga wire. Are you freaking out about how many feet long the wire run is? To the point where one foot of wire length is a big deal?
Next, this point of view: 12 ga wire has a resistance* of 1.588 ohms per thousand feet, that six inches of 12 ga wire would add 0.794 MILLIohms to your wire run.
I could use something like a Wago connector tying the 3ea 12ga (2x to amp and 1x to surge) then repeat on other side of AmpPro.
A Wago connector, or any other connector that just slides or snaps together, would probably add more resistance than that six-inch wire tail.
*Find a chart of wire sizes and resistance and put it in your "Tech Info"** computer directory so you can easily look up actual numbers when you're debating what to do.
**Really -- each of us should have a section of files like this. CATV channel frequencies. Bolt sizes. Bolt strength. Electronic formulas. all kind of stuff.
