The Supra manual says use 1 or 2 and only both if you need a last chance to start, also never turn to off while the boat is running.
The one interesting thing the manual says is use “dual purpose” batteries.
My dealer installed marine deep cycle batteries.

Is it correct in that the pop only happens when the stereo is on and you crank the boat? No pop if you turn on the stereo with engine off, or wait to turn it on after the engine is running? The recommendation to run on 1+2 seems like they are chasing a voltage sag.
First have to determine which circuit is falling out of sequence. Is it the IGN turn-on? (may not even be one). Is it the constant B+? Or is it the amps hitting their voltage threshold and cycling off then back on.
Both the ground and B+ share the load equally, so if one needs to be upped, both would, unless one is smaller then the other, which would be odd.
Load, or stress on the charging system is relative to the discharged level. So two batteries can be now more load to the alternator then one battery. Think of audio amplifiers. five 100W amps are in theory, no more of a load then a single 500W amp. Same with batteries.
A large stiffening CAP may "fix" the issue, but they can be a liability to the battery(s) on toys that are not used regularly.

Battery type
Only pops when you start boat with radio on.
I am surprised Supra hasn’t fixed this yet

06-04-2019, 06:52 PM #26Wonder if these new boats come with an ACR, or automatic charging relay?
With the DCP switch and ACR, the house loads are isolated from the engine loads, so there would never be a voltage drop on the house side, created by the engine side.

Supra does not recommend running in 1+2 mode.

Not sure why having the switch and having HD alternator if they don't want to simultaneously charge all of the battery banks. I can see issues if one didn't know how or when to operate the switch. They should automate it then as the motor home industry has been doing for years.

Not the prettiest setup but I added an acr this winter to my 16 mojo, works great. Worth the time installing.
