Cal2vin! We have the same boat and I'm getting ready to replace the one factory JL amp with 2 new ones. Am I correct when I say the factory wiring runs from the batteries to the 3 way battery switch and then to a fuse at the helm before it runs out to the amp itself? Reason I'm asking is this... If I run new power and ground wire directly from the battery to the new amps , what happens to the factory wiring which currently connects to the amp?
Also, if I remember correctly, my two batteries are not connected in parallel. I don't recall seeing any wiring connecting the 2 neg posts and the 2 positive posts of the 2 batteries. Will this become an issue if I run new power and ground wire from one of the batteries only?
