Hi,
I am about 20 hours into my soundproofing project. I ran a rear view camera and wires for a rear door popper. Stripping took me about 4 hours. Putting things back is more time consuming. I wanted to get the front carpet and seats back in after soundproofing the floors, so the car will be drivable. The seats and center console need quite a bit of persuading because of the extra thickness involved. The floors seem totally dead. Since my interior is still out, I can't evaluate the overall sound level since I have bare metal from floors up. We'll see in the next week or so. Maybe 12 more hours of work, maybe more.
