The cables for the speakers were done like this.
Isolated.
All the wiring I've put in the doors have been straped to the original wires so no wire is loose. I also put the original audio connectors (for the tweeter and the midbass speaker) in the clothing material and straped it to original wires so that they won't bang against the doors and make noise.
After it the speakers went in, the tweeters went in and I've put the door panels back on - the same way as I've took them off just the other way around.
This is the end of part 1. I'd put it all in one long post but the forum is limited to 4 pictures per post. Maybe a moderator/admin can merge my posts into one.
Tomorrow I'll show you how and where to put 35mm2 power cable, how to get the cables (power, speaker, RCA) to the back, how to take the rear seats out and how to make good ground for the amplifier. Later on (when I'll have time) I'll make a fiberglass box in the trunk for the 10" subwoofer.
Thank you for listening, I'm opened to questions.
