[QUOTE="killahbean, post: 1313800, member: 552462"] It is safe, all you have to do is MAKE sure positive dont touch ANY ground/ AND negative dont touch power.....And isolate the speaker wires..... The worse that can happen is you'll blow the head unit for good or you'll just blow the fuse on the unit thats why you'll have to do it carefully..... I've done this NUMEROUS times and this is also the method I use when I purchase a used head unit from somebody....u can actually get the unit to produce sound connecting a speaker to it....lol [/QUOTE]
