Installed a new deck.....The old deck was a sony 35x4 the new deck is Kenwood....50x4...The problem is anytime it pulls too much power..or I trim the outdrive it shuts down...started doing this while the boat was off and by turning the volume up past 24....any suggestions or ideas...please help

Um ok. But what is up with the title of this thread? <BR> <BR>Check your connections. Does the power wire have a good connection. Try running a direct line to the battery. If the power wire is attached to the same power wire to the outdrive then it could be draining the power.
