I have to Blue top batteries that I would like to install, for help with Stereo and tower speaker loads, The batteries can fit under the bench seat starboard side if I lay them on there side, any concerns with this? also I picked up a 70amp Mercruiser Battery isolator for three batteries that I found sitting on the shelf at local marine supply, if I isolate all high amp stereo functions to new batteries would this be good, or do I require a perko switch? any ideas welcome,
