Would be great if anyone can confirm the maximum size of the Audio Speaker that can fit in the Dashboard of Probox without modification. If I am not wrong the original speaker is 4 inch round... pls confirm? Also has anyone installed 4 inch X 6 inch speaker without any modification.
Secondly, is there any 1Din audio system available in the market that fits in the dashboard console of Probox. I would like to avoid using plastic frame on the side of the audio system to cover the Gap. Pls also note that I am interested in High Quality Sound and I do not want loud systems and I hate the after market "flashy" Kenwoods/Pioneers available in the market. So something more subtle as the original players that come with the car.
