Hey guys I realize this thread is over a year old but Im having a lot of trouble getting my sub to work! I looked all over the web and finally found this post and thought my troubles had ended, but of course i was wrong! Ok so I have a LOC that has 4 wires coming from my LOC, its a scosche LOC and the installation directions say that I need to hook up the wires to a positive and a neg speaker wires. I do not have a ground wire on it just wires to connect to the speaker wires. so I hooked up all my wires just as Ivory said to and I had no luck with my sub working. I know my amp works because its been tested. Chillery said he hooked up to a blue and green wires but which ones? Some people say that they hooked up to the "low level" wires. Any help would be great!
