I have install my Riocar in my 99 Jeep Wrangler Amp mounted in the trunk area. Here is my problem whenever I turn on the windshield wiper (only the first time or if I haven't turned it on for the last 5-10 minutes) my amp powers down for 3-5 seconds. I think this may be due to too much draw on the electrical system, does this seem right, or could it be a grounding issue. Any suggestions on what to check for would be greatly appreciated.
