Are the speakers in the front door only supposed to play bass? Just noticed it and I thought it was kinda weird that it isn't a full range speaker.

I believe the lower door speakers are 10 inch subs if you have the Bose system. They do this because there are a bunch of tweeters in the front, which will give you your mids and highs. I know on the Q50 they use a 10 inch in the front doors, which is why I am assuming it is the same. Hope this helps!

Speaking about this, would you guys ever consider getting dynamat applied to the panels to make your audio system sound better?

I'm actually considering installing Dynamat mainly to further reduce noise, but I know it will definitely clarify the audio as well.

I have not seen anyone do it in this vehicle, but it does work very well with both road noise, and sound quality. It does add a bunch of weight to the vehicle though.

I look forward to seeing that, when do you think you're going to do it?

I'm aiming for the end of June (busy with work and other things until then). Also, I need to figure out how much Dynamat material I need.

Nice, decent timing, I would say take it to an audio/video shop but this stuff takes TIME and would get charged like crazy for labor.

Have you decided where exactly you want to line with dynamat?

I did get quotes from a couple of car audio shops, which ranged about $400-$450. The cost of the amount dynamat material needed is about $150 (with a total added weight of about 30-40lbs). I also found came across a webpage where someone had installed soundproofing in the doors of a ’13 or ’14 pathfinder, which seems very similar (if not nearly identical in structure/framing to the QX60). With that said, I will first see if I can remove the door paneling myself. If successful with no real issues, then I foresee adding the sound dampening material to a few spots on the inside of the outer door sheet metal, around the speaker housing of the inner door frame, and in a few other spots of the inner door frame. That’s the plan, but we’ll see how it goes (e.g., time, other competing priorities, ease/level of effort).
A consideration I currently have is whether or not the sound dampening sheets will make a significant difference in the QX60. I’m sure it makes a huge difference in other vehicles like a Civic or Chrysler 200 where the interior is a bit noisier than a luxury vehicle, but am not sure about the QX60 since it’s a luxury vehicle that is fairly quiet enough and should already have some sound dampening material in the doors. Also, while I’m sure the sound dampening will help some (if not significantly), there’s still some noise and vibrations on the floor board side (as well as windows). I don’t plan to add sound dampening sheets on the floorboard mainly because it seems a bit difficult considering all the carpeting and Styrofoam underneath it. Plus the car audio shops recommended against it for the QX60. With that said, I am considering spraying rubberized undercoating in addition to some that already exist underneath the vehicle (which I noticed when getting underneath the car to install my new running boards) as well as to the wheel well linings.

I was amazed with how quiet this vehicle really is yesterday. I've owned several Prius and a Volt before this so obviously road noise/outside noise was a problem with them, a bit less in the Volt than the Prius.

So yesterday I was sitting in my car with my mom and son and on the corner behind us there were two guys with jack hammers going; They're repaving the streets around where I live. While I could hear it in the car of course we had conversations going on just fine for several minutes. After a bit when it was time for him to go into his school and we opened the doors, WOW, was it loud outside. The stock sound proofing done on this vehicle is actually pretty good.

Not saying dynamat wouldn't help even more but unless one will be keeping the vehicle for quite a long time, I dunno, I'd save the money. If keeping it for more than 3-4 years heck, why not, I'm sure it'd make it ultra quiet!

I agree. The QX60 is fairly quiet. That's why I haven't really jumped at it just yet.... again, I'm sure it'll help it, though not sure if the difference for the QX60 will be significant enough to justify the cost. The only noise that I do get tired of occasionally is the typical drone-like Infiniti engine/muffler sound. It sounds awesome when I'm in a sporty mental mode (and especially in the G37). But other times, I feel it's a bit annoying. I would actually like to dampening this sound if I could. I've even thought about dampening the firewall area (not sure yet if that's worth it or even a good idea). Any suggestions?
