Sinemeup, others.. clearly you have no understanding of how electricity works. and the brilliance of this design is that at no time could high current ever flow through the smaller wire...
It's moved the entire power source for the stereo to the trunk and isolated it from the main feed... and changed the main power feed into a simple charging circuit.
and since 4 gauge handles three times the possible max charging current Im likely to see, whats happening here is a bunch of idiot forum trolls with bad install habits trying to hate on a serious overkill system
peace.. kiddies.

Please sir, can I have some more.
We are not disputing your design, we are in fact disputing the FACT that you have serious errors about your understanding of current and how it pertains to the electrical system and demand in the vehicle. For example, are you still telling me that the battery in the back is running the stereo?

So seeing as your stereo is run off your rear battery and your only running 4ga from the front to the back is that 4 ga fused? Seein as you believe your stereo is run off just your rear battery and your 4ga will never see more than 40a ( according to you) why dont you try fusing that 4ga line at 40a and see how long that fuse lasts before popping. I have no idea what you have for a stereo but if your adding a second battery im going to assume you have a fair bit of draw and that fuse wont last at all.

There is nothing wrong with starting the vehicle with both batteries. If the wire to the rear is on the small side the resistance will force the front battery to supply more of the starting current. In this case the wire becomes part of the load seen by the rear battery. Because of this (and the short time span) the wire would have to be quite small before there would be any danger.
That said the design is fine. It hurts nothing and will allow the rear battery to drain while parked and keep the front battery charged to start the car.
