All done with the install in the back cargo area to the back seats. Final sound reduction was between 10+ db. From my original reading of 82 db now its down to 69-72db.
I have yet to do the front cabin area and with this recent improvement I've a new found motivation to do it. However, it was a LOT of work and having spent 20+ hrs in the back of an SUV over the weekend, I'll be honest it's not something I enjoyed but knowing it done right is something. Granted, I saved a bucket of money but was away from my wife & daughter too much. That's always the case isn't it? Time or money. I'm glad it's almost done but next time I'll pay a young'n to do it.
