sound system amplifier

2004 342 FV  my sound amp is connected to the stbd engine battery
 doesn't make sense to me   why would the single largest load be fed from a starting battery
 are all the 342 wired this way??

Will check mine this weekend, I thought mine came of the house bat. This is all so both amps?

Mine is connected to the house battery. Someone rewired yours. My amp would last about 15 min on my old house batteries.  Actually it was my best indicator that the batteries were going bad and needed to be replaced.

No, it should definitely be wired to the house battery.  Should be a red 2-gauge wire direct to the battery.  Sounds like somebody accidentally connected it to the wrong battery.

thankyou for the response, the daughter and son in law had the boat out and told me when they shut off the stbd guest batt isolator the amp shut off also.
 that would mean the feed for the amp would come from the load side of the switch
and not direct from a battery. think i better do some more investigating

LaRea

It's only the stereo head unit that is wired to the battery switch (or, on some boats, to an ignition switch).  The head unit has a separate wire running to the amp that turns on the amp when you turn on the head unit.

The amps are wired direct to the battery.

Although, this schematic shows the head unit connected via the DC Main rather than the battery switch.

so batt 2 shuts off the head unit, and indirectly the whole system  got that
now to check this drwg out

now i see batt#2 shuts off stereo memory. the stereo is powered from cabin panel
the amps from house batt
now to figure what stereo memory does?? programable to control cockpit speakers??

Where is that 7 amp fuse located? Someone was asking a while back. I think on a 342 it is on the main cabin panel.

mrjdasr

i think that 7 amp fuse location is the key it needs constant power for the stereo memory  ahunting we will go starting with the line side of that 70 amp fuse

this 342 FV has a serious sound system

The stereo memory is what keeps your preset stations in the radio along with the clock.
