Hi @fj_cruiser
It is not very clear to me what you are looking for. You want to listen to lectures and podcasts while driving without having to put it on high volume, correct ?
In my opinion, the FJ cruiser having the aerodynamics of a cow, it will always be loud inside the cabin while driving, but there are are few options to reduce it:
- Good quality highway tires. Michelin has some of the quietest tires. Heavy all terrain tires will be too noisy.
- Cabin insulation. It is possible to insulate the cabin more with sound-deadening panels. This will surely help but is quite a bit of work. Some information can be found in below topics:
if all above does not work, i suggest try using airpods or changing the car
