On the zones it’s an easy fix. Remove 4th zone which is bow and tie them in with cabin.

Having had two supras I found no way to get system sounding right without a line driver. Never tried external eq but I suspect it would have worked.

When I first got the boat the gains were cranked. It would blow your ears off by 25 on the volume lol.
I tuned it by pairs on the amp. It sounds great, but there’s still some hiss, even with the gains all the way down and the motor off. It’s nothing anyone would ever notice at this point, but it still bugs me. I know it’s there and that’s all that matters!

In my experience, JL amps always tend to be a little noisy from the start anyway. They’re super sensitive. I could almost bet if I threw a 6 channel Kicker KXA or iQ in there the hiss would be gone.
I love JL, just not the amps.
