I was sitting in the parking lot at work listning to music. The sub wasnt beating hard, but it was loud. I look at the display and it is going crazy, led's turning on and off, the arrows were lighting up randomly. I turned off the music, and the remote display turned off all the way. I checked all my connections, and they are all good. The only connection that can possibly be the problem. The port where the RJ-11 plugs in is kind of blocked by the location so the wire is a bit tweaked.
I tried the remote display tonight using the regular ciggy lighter, and it works fine.
What else would you recomend to check out.
