Relocating batteries & Mounting amps
Not to hijack but when is it recommended to go with 3 batteries over 2? I have two now but was thinking of adding another and getting a Prosport20 plus charger. Also, when should someone think up upgrading the alternator?
Right now I have two amps and probably by the end of the summer I will have three. Two Syn4s and a syn2 if I add another set of tower speakers in the future it would be another Syn4 for a future total of 4.

E4,
Its all about play time will anchored, and thats all. How many Ah (amp hours) will be determined by the approximate current draw of your system at a given volume level x how long you want to play on the water with the engine off. This will then be divided by what size batteries you go with.
if someone never plays while anchored, then they only need a single battery for the all duties. if they want to spend some time playing while anchored, then a dual battery setup is recommend. For those that want to spend an entire weekend jammin while anchored, then it will be a sizable bank with a lot of large batteries.

Rarely do you need an alternator upgrade if your charging system is otherwise well planned. If you had an inordinately large system, routinely used your boat long weekends camping at a remote destination without over night access to AC power, then a big alternator could be an essential upgrade.
Your stereo battery bank should be large enough that your typical playtime at rest does not deplete the deep cycle batteries below 50% (12.0 volts). So you will know by simply measuring the voltage after a long period playing at rest. Then the battery charger size and capacity is matched to the size of the collective battery reserves. For example, if you had three group 29s for the stereo plus a single group 24 for starting, then a 30 amp charger is a bit undersized while a 40 amp charger is max. A ProSport 20 would be perfect for three total group 24s.

That would be okay if you just had one stereo battery. But I wouldn't split up two identical stereo batteries by much distance if I could avoid it in an ideal world. Look, there are conflicts with any charging system that has two banks that are used differently off one alternator. So I am not going to state that it is a prefect scenario now. However, if I had dual stereo batteries, then I would prefer to have two identical batteries in age, size and chemistry....and that would include equal cable size, distance and resistance. Just a base foundation to follow, and not something that is an absolute if you have a good reason to do otherwise.

Re: Relocating batteries & Mounting amps
Here's mine... 1 starting behind the observers seat, 2 in the bow in front of the hump. Note: I had to relocate my heater but totally worth the space. For reference these are all group 31 agm's.

I like that set up. I just feel like all that space from the hump to the IBS is going to waste! Need to stick something in there and batteries would free up space behind the observer seat for items you actually need to access often
