wierd after install

[irondiezl3]

so did my install which ive always done myself. ive been fortunate enough to work with alot of good people to learn alot of things. never had a problem with a install. put my double din in my 04 with the module. everything works great. except today a week after install i went to start my car it had power but was acting as if it was dead when i turned the key. i heard a clocking in the passenger fuse panel i checked it nothing was blown. now i pulled out the radio/start fuse and bamn fixed it. now since then this hasnt hapened again and prior to this i never had any problems at all and i know its for sure connected correctly i checked it over. was this a freak accident? im nervous its gunna happen again. anyone have any ideas or related issues?
