Help hooking up Car stereo in Trailer?

[alpineman]

I have a enclosed trailer, I have installed a JVC car stereo, connected ground to body frame of trailer, front speakers, and antenna. problem I am not sure about is for power there is a yellow wire which says to hook it up to a live wire which I have done, I have not hooked up the red wire which is said to go through the ignition switch on a car (which I do not have).
My question if someone can help me is when I hook up the power on the unit it turns on for about 5 seconds than turns off and I cannot get anything to turn on after that, Do I need to connect the red wire for ignition directly to the power source also with the yellow or just the red wire ? also I would like to run a inline fuse what size would you recommend.

Thanks

the yellow wire is to go to direct power to keep the memory presets etc. the red wire is the main power, it should be fused. hook the yellow and red together, you will have to turn off your stereo manually every time, or run a toggle to cut the power to the red wire to not drain your battery. the red wire is so that your stereo powers up when you turn the key to "run" or "acc".

I would use a 25-35 amp fuse if your deck has built in power amplification.

I did the same set up in a tiny camper years ago. I used a toggle switch to cut power to the stereo when not in use. The power for the memory is minimal, but if the stereo has a lighted front, that will run the battery down in time. My current camper has a stereo with a removable faceplate. If I just take that off, it cuts off all the fancy lights for the display. The memory is all that has power then. Seems to not really affect the battery.

Yeap, on mine the yellow's just to enable the thing... not much current draw on that, but it has to see 12V to "turn on". Power comes from the red wire.

I'd just yank off the faceplate to turn it off.... even if the stereo's off and the faceplate's on, it's not going to draw much current.

Thanks all
I hooked up the red and yellow direct I will install a fuse inline on the red, and will remove the faceplate to preserve power tried it and it works great.

Thanks again
