Has anyone sound deadened(spelling? word? :laugh) their Cadenza yet? I hate the little rattle and small cracking sounds the car makes when going over bumps or bumping your favorite music. Was thinking about gutting the car and applying sound deadener mats. Had a couple of concerns about price and difficulty of actually doing it.

I haven't but always wondered. I think you'll find it hard to do as I think most of that comes from the roof/glass areas. I know a few of them may be near door plastics and maybe the sunglasses holder thingy. I was looking at possibly getting a Fiat 124 Spider Abarth or MX-5 and was looking into dynamats. That stuff looks like it gets pretty expensive quick though.

Would love to see some responses here. I wonder if adding any material to the firewall or door panels would help.

I would think the floor of the back seat and trunk wall/floor would be ideal. I noted after taking out the lower seat to transport a load there was a lot of road noise coming from the bare metal under it, in that it is just the seat stopping that noise.

And I've also noted after long trips, the floor of the trunk is hot from the exhaust heat radiating up through the floor. I'd think some kind of insulation there would help with temp/sound, and may make aftermarket bass in the trunk sound a bit better too..


All that said, drove my wife's 2016 platinum Max today right after having driven my car. Man is that thing noisy and stiff compared to the Cadenza. Performance wise it's far superior to the Kia, but as far as quiet and comfort, it comes up real short. My point being, Kia already put some decent effort into this car already, so I wouldn't expect huge gains overall even if you put in 200 lbs of deadening in.

I'm pretty sure that junk that's been sprayed (it looks like rhino lining) on the bottom of our cars is for sound deadening now that I think about it. You only really see our exhaust pipes running through the bottom of the car, everything else is all covered, it's pretty nice. I'm with MadMax though, probably under the back seats if you feel that motivated and maybe in the trunk. past that though I'm not sure you'll to any more good than harm. We just kind of live with the pops and whatnot, it seems to be a symptom of the glass roof as far as I know (my first full glass roof).
