I just bought an alpine 9813 not too long ago and it starts to turn on and off. I had an nakamichi deck before and it use to do this before also.

I checked all my connections and they seem to be good. The connections are all soldered and heat shrinked. I also have an alpine alarm that I installed myself and a few kill switches. (thought it might help to add wiring history )

What gets me is that everytime I signal or something, the deck would just turn off if I was lucky enough for it to stay on durin that time. This really makes driving my car sucky because of this. Any help would appreciated. Thanks!

 

Well,, im guessing a loose connection such as a loose ground is your problem (usally i know its a loose ground when im driving, hit a bump and radio turns off and on). Im guessing you may have missed something someplace.. if anything try connecting your HU to a different 12v source and see if it stays on

 

ill go check.

anymore help would be nice.
