Hello friends, I cannot find the cables of the 2006 model 307 in the original sound system on the front side - under the windshield, on the right and left, inside the door or behind the tape. No sound from tweeters. I don't think the tweeters are bad.
I do not give the previous owner sound systems, the entire woofer and the amplifier have come off beautifully so that there is no trace of cables when dismantled. There was no sound from the door pillars and plain front doors were working. I removed the doors and there were JBL 50w mid columns. I couldn't get them .. I found the cable connections and now there are sounds coming from all 4 doors. but I cannot hear sound from the tweeters on the front.
