Or do I put the tweeters on the head unit zone 1 as zone one is hard wired to the head units wiring harness. And zone 2 and 3 have RCA red and white and then zone 4 is a subwoofer zone with only one RCA coming out??? I’m really having a hard time on what to do with all the speaker wires do I connect sets of speakers before hooking them into amp and I know someone on here will know exactly what should be the best way to do this

Alright, I'll take a stab at this. First off, you're going to need more amps if you want to send enough power to all your speakers. Another 4 channel amp to power your tower speakers and Tweeters.

Not using Equalizer:

Amp 1, 1000W, 4ch
Zone 1 RCA -> Ch1 - Bow + Driver left 6.5" speakers wired in parallel - 250W at 2ohm - 125W to each speaker
Zone 1 RCA -> Ch2 - Bow + Driver right 6.5" speakers wired in parallel - 250W at 2ohm - 125W to each speaker
Zone 1 RCA -> Ch3 - Back seat left 6.5" speaker - 150W at 4ohm
Zone 1 RCA -> Ch4 - Back seat right 6.5" speaker - 150W at 4ohm

Amp 2, ????W, 4ch (this is the one you have to buy)
Zone 1 RCA -> Ch1 - Tweeter left speaker - 90W at 4ohm
Zone 1 RCA -> Ch2 - Tweeter right speaker - 90W at 4ohm
Zone 2 RCA -> Ch3 - Tower left 6.5" pair wired in parallel - 170W at 2ohm - 85W to each speaker
Zone 2 RCA -> Ch4 - Tower left 6.5" pair wired in parallel - 170W at 2ohm - 85W to each speaker

Amp 3, 1500W, 1ch
Zone 3 RCA -> Ch1 - Subwoofer left + right speakers configured for 4 ohm wired in parallel - 930W at 2ohm - 465W each

Do not use Zone 1 on the head unit.

If you want to use the equalizer, then just feed Zone2 from your head unit to it's input, then the equalizer "front" goes where it says "Zone 1" above, "rear" goes where it says "Zone 2" above, and "sub" goes where it says "Zone 3" above. I see the equalizer as unnecessary given your head unit allows you to have the same level of control. If the equalizer is easier to operate than navigating the menus on the head unit, then use it. If not, just leave it out.

With this configuration, you wont have a traditional Front/rear fade control, instead Front/rear fade will control cabin/tower. This way you can turn up or down the boat speakers relative to the tower speakers and vice versa. Normal front/rear fade is kinda useless in a boat.

FYI you will need a RCA Y splitter and two RCA cables to be able to send Zone 1 (or Front if using equalizer) to two different Amp's inputs.
On Amp 2, you will want to get one that allows you to set the crossover to high pass filter for the tweeters.
