radio turns off when volume is turned up
Does anyone have any idea why stereo would shut off when radio is turned up to around 25. Comes right back on but shuts off again. Thiught it may be amp but continued to do it with amp disconnected. It is stock kenwood that came with boat, with stock speakers

Typically, the only time that a head unit will shut off is when it sees a short on the speaker wires/ terminals (or something close to it) or the amp is getting too hot. Either way, I would check that none of your speaker wires are touching in any way. There is no reason why the head unit should not turn up loud enough for the speakers to start distorting before it shuts off.'08 Mobius LSV, Mods- 1100 lb Rear Sacs, IBS Sac, Center 400 Sac, Dedicated thru-hull intakes and pumps per sac, SeaDek One Piece Mica over Black Roo, EZ Net Cargo Nets, Swivel Drivers Seat, Hot Water Shower, Hinged Wind Block, Bow Cushion Adapter Plate for Drink Holders Access, etc, etc.

My '04 factory set up was exactly the same way. My recommednation is to replace head unit, all factory speakers and add a 10" sub and tower speakers. That should fix your problem and improve your sound quality. lol06 LSV

If that doesn't work, just replace the boat with a new 2011 model.My Mom said I'm not allowed to get wet!

I had this problem for a while and it took a while to figure out. What was happening with mine, was that the battery could not suppply enough power to the stereo. When the volume is low, the power draw isn't that much, but as soon as it is turned up, the amps begin sucking power from the battery(ies). I even had this problem after adding a second battery. The stock alternator could not keep up with the power draw of the stereo at high volume. I also read somewhere that automotive alternators are not very good at charging deep cycle batteries. My stereo could draw a fully charged group 27 deep cycle battery down low enough that the stereo would not play after only two trips to the lake. I bought a deep cycle trickle charger and as soon as I get the boat back in the garage, the charger gets plugged in.Brian Roberts

I bought a new sony stereo for my boat and had the exact same problem. Just ran a ground wire from my stereo directly to the negative terminal on my battery. Problem solved.
