Hi PM for Perodua Bezza.

My problem is that I normally turn on the volume super loud when I'm making handsfree call.

But the sound is clearly heard outside my car, even from across the road, outside my house, my parents can hear from their room!

Then I noticed that even my normal radio music also can hear if I turn the volume up above average.

To solve this problem, I was thinking I want to do 4door package.
Do I need to do the floor + firewall also?

Quote best price for 2 options:
- 4 doors only
- 4 doors + Floor & Firewall

Thanks.
