here is my question..I do want to add at least one sub in the cockpit to this later (possibly now just to get it all done at once) but not sure if a 4 channel will work for what I want and looking at pic of head unit there are only RCA outputs for front and rear speakers..
I did plan on hooking up all 4 cockpit to rear channel and 2 cabin speakers up to forward channel so I can isolate at night when I want to listen to music or watch a movie without disturbing neighbors..is that possible..if not I can live without that option! Here are the two amps I am considering!

Sorry for the long boring message but I wanted to include as much info for those that know to hopefully help me out..any help would be appreciated greatly!

Not that I think it will matter but here are some pics of the components I have gathered so far!





Thanks Again..any help with choice and suggestions on how to wire up would be appreciated!

It may have changed as I havent messed with audio in a few years, but a 5 channel amp was always a compromise. i was allways better to run a seperate amb for the bottom end and tune with a good active crossover. How you mount/enclose your speakers also make a HUGE difference. I had a ford ranger in my younger days, had 2 sets of component mids/tweets on a 4 channel, 2 8's on their own amp for mid base and 2 12,s own their own amp for the bottom.... It sounded ok but got a little muddy at volume. Took the time to build enclosures for everything to exact spec, sealed them good etc. Next problem was buying a new window for the back of the cab as I blew it completely out of the rubber gasket and the sound was worlds better,

Look at JL audios MHD 900/5 amp pricy but I couldn't be happier with how it sounds. I have a set of JL 7.7s, 6.5s and an M10 sub

I had the same question....just bought a new Kenwood marine head unit. I called Kenwood customer service to confirm that the front and rear outputs were putting out the same signal and they confirmed that they were. I'm used to home theater where front and rear mean VERY different sound signals are sent to the speakers from the receiver.

I'm hooking up my cabin speakers to an amp hooked to the front outputs, and the cockpit speakers to an amp hooked up to the rear outputs. I figure I can just use the fader control on the head unit to kill the music in one area or the other.

I was also thinking about putting in subwoofers later, but bit the bullet and bought a couple JL 10's for under my back seat (building boxes in the seat compartment) and a JL 500/1 to run them. I figure if I am going to have to crawl all around the boat running wiring, I am only going to do it once. I would also highly recommend getting a dedicated amp to run your sub(s).

DYVMASTER-That head unit is what I have decided on myself , as it has 3 sets of 2.5v outputs-front,rear and a dedicated sub output,not just 2. Plenty of flexibility there. I myself will be running 1 4 channel amp off the front and rear outputs for my componets, and then utilise the sub output for a 2 channel amp pushing 2 10" subs. After looking at the options , I think the Sony CDX-M60UI is a good unit for the $$$, it offers a lot of flexibility and desirable features.. As stated before, the 5 channel amps are ok for ease of/cleaner installation, but a dedicated sub amp will push out more/cleaner sounding power.

I have a M1200 mono Rockford amp powering 2 10" Rockford subs and a Rockford M600 2 channel powering 2 Rockford M282's and 2 Rockford M262's. It must be good because my lady keeps telling me to turn it down it's vibrating the seats!!! Lmao
Have fun with it !!!

Thanks for the help guys..and Masonbig1..I looked over the Specs I posted and I suppose if I would have read them more thoroughly I would have seen that..Time will be the factor for me as far as if the subs get put in this time or not..I am out at sea now and gathering parts but I will only have 4-5 days to buff..wax..clean prep install new toys plus shakedown the ol girl after a winter port engine rebuild to make sure I can trust her to make a run to PIB..plus I have some ideas for custom installation of my subs that will take time..dont want to just throw and go..I agree though..would like to do it all at once but time isnt on my side! Its good to know the front and rear put out the same signal (thanks mike_mds) and that there is a seperate out for the sub as well..for this leave I think Ill get the 4 channel and hook up what I have and plan my install of subs..gather those parts and have the custom plates I have in mind cut and install next leave..as long as I can rock while Im running and sitting at the dock with a cold one Ill be pacified for now! Thanks again for the input

DYVMASTER-To save some time later, if you have a spot planned for a sub amp, go ahead an run your RCA's to there while installing head unit, no sense on have to do it twice.

Formulas spot according to wiring diagrams is in the cubby above the fridge..I planned on putting the 4 channel there as well as the sub if there is room to mount..is there a benefit to having amp closer to sub?
