First post

New owner of a Supra 21 Launch.

First job: adding amps, sub and tower speakers to the stock kenwood.

I have an additional deep cycle battery. What is the best method of wiring a second battery?

Is the Perko style selector preferred? I've read they can be a bit finicky.

How about something like this?

I'd rather have an "automated" switcher, if possible.

Thanks !
