I replaced the front speakers in a 1995 4runner i recently bought hand noticed that the stereo was wired all crazy. the back speakers were not working properly and the power anttena would not work. So I am trying to straighten all of the mess out. The factory wiring harness was cut out and I have figured out the front but the back speakers have tweeters built into the roof and I cant get them to work properly. They cut out at times and when you turn head lights on they go off. Please help!!!
