Stereo Goes off at times

Boat is a 2000 FIesta Vee 242.
PO had a 15 inch sub, amps, all new JL Audio speakers and a head unit. Also had extra batteries installed. One side has 2 deep cycle marine batteries and the other side is 2 blue top optimas. System sounds great and everything, however stereo will be on and working fine and if i hit the blower switch, or nav lights or anything the stereo will shut off and right back on. adjusting Trim Tabs will also cause it to go off at times. However it will only do this SOMETIMES not everytime so its not seeming like the switches are turning it off, more of overloading power and the stereo is the one that suffers. all the electronics seem to work fine and i can run blower, bilge, and all lights at the same time and stereo will still operate, it just shuts off when i hit the switch at times. Does it when docked and hooked to shore power as well as when sitting on batteries and when driving.
Furthermore, im not sure but my battery gauge drops down below 12 when sitting and the engine will seem to struggle to turn over after sitting for awhile even when i sit on battery bank 2 and switch back to bank one to start. When driving the gauge only goes a little above 12 so im wondering if im not charging real well.
Anyways, sorry about the lengthy post but hoping for some help and getting it sorted out before labor day. Thanks in advance for any input!

Since you mention you have two battery banks I assume there is a selector switch (often red color) with selection options such as OFF or 1 or 2 or 1+2, this is called a battery switch. If this is wired correctly your starting battery bank (probably the blue top optimas) and your house batteries (probably the two deep cycles) should be isolated UNLESS you have selected 1+2 - which should only be done as a "bridge" for emergency start (imo). If your batteries only show a charge of 12 volts at cruise I believe they are not being properly charged. My batteries (which are AGMs) charge at 13.6 volts while at cruising speed (3300+ rpms) IF and I repeat IF both sets of batteries have been properly isolated and both show signs of undercharging I suspect your charging system ie alternator, battery charger etc. is at fault. Of course (assuming your battery selector is wired properly) checking all battery connections and particularly the grounds (including for your stereo) would be my first item of action.
