Of note, the two quotes I received were $55/door and $75/door to install Noico sound-reducing mat on all my doors, including the hatch. Plus another $350 I'd imagine to do under the cargo floor. I needed ~$140 in materials to do it, so it would have been ~$500-600 had I had it done professionally, and I have no way of knowing how thorough they would have been. Plus, indeed, the OEM hood liner is several hundred dollars, so you certainly would approach that $1000 mark do have it all done professionally. The same Noico mat can be used under the hood, for about $15 and made a notable difference for me.
I did all my interior sound deadening work in around 5 hours, I believe.
I even stuck a big piece on the sunroof glass since I either leave it covered, or open it completely.
The doors, hatch, and under the cargo area made a significant notable difference to me. The piece on the sunroof glass knocked out a bit more of the remaining wind noise from the roof bars. I usually drive to work at 55mph, and listen to music at around "15" on the volume, if that tells you anything.
The last noisy thing for me are my tires. I didnt notice them until I did all the sound deadening, and now they are the loudest thing--not horrible, but a noticable whirring sound above 30mph. Unfortunately, they only have 5k miles on them, they otherwise perform great in rain, snow, and offroad, and I am already on my third set for this vehicle after two wheel changes lol.
Indeed, noise is the one complaint most have a out Ravs, but it certainly is fixable.
