I'm a noob at this stuff and I just wanted to know what would happen if i straight up plugged my 2 12'' subs from my car into my mini hifi system. My subs have the red/black wires which is the same as my speakers (i also have a subwoofer out plug in the back that would be similar looking to a video in/out or something on a tv). I've done this before for a few days a few years ago and it worked fine for me, but ive heard this isn't good for the speakers. What does it do to the speakers/system? Do i need some sort of converter? Also, is there a way to convert the red/black wire set up to allow it to plug into the subwoofer input? Thanks a lot guys, i appreciate it.
