Hello,
I must apologize in advance, I am a novice when it comes to marine vehicles.
I just bought my first boat couple of weeks ago. It's a 1990 Searay 200 Overnighter. The boat came with the group 24 1000MCA starting battery installed. It works absolutely fine, but I am in the process of wiring her with 8 speakers, 1 sub and a 900W amplifier. While I do enjoy music, I hate being stranded. And taking into count the fact that I cannot swim, being stranded on the water is a bit terrifying to me.
I talked this over with several "boat" people and everyone just says "throw a deep cycle in there, wire in parallel and call it a day." I am not new to dual battery setups. I run them in my jeeps and my truck, all in parallel, no isolators or switches. Here though I would like to do a "proper" install. I have found a wiring diagram, searching this forum, for running two batteries through 1/all/2/off switch. It is pretty clear and easy.
However, I do have following questions:
1) Do I need to wire the amplifier power to the DC(deep cycle) battery directly, or to the DC side of the battery switch?
2) I can fit group 27 battery alongside of the 24. Should I keep the 24 starting and go with 27DC or do the groups need to match? As in 24 start 24DC, 27 Start 27DC? Batteries in my other vehicles are twins.
3) I can also fit two 27 batts side by side. Now 27s are around 55Lbs, 24s are only 45. If I add 2nd 24DC I am adding additional 45lbs to the right side of the stern. If I go with two 27s I will be adding additional 65lbs. Will that compromise the safety of the vessel in any way having so much additional weight on one side? I have checked the plywood under the battery it seems to be very solid. The board itself should be able to handle the weight just fine.
I apologize for the lengthy post, most of this is new to me.
I do not have any additional electronics running, just the stereo and vhf radio, no fish finder.
Thank you!
