Hello... I am a new member and have a question already. I am upgrading stereo. Have a new HU, dash adapter and wiring adapter. My 99 TJ SE appears to have wiring for rear speakers, but I can not find where the leads end. Can someone advise / Help. All set except can't find where the speaker wires lead to in the back. Note: No original soundbar equipment. Is there wire going to the back? Thanks for any and all guidance.
