Upgrading speakers in the T350?

[chiz]

Hello,

I have a 2002 Tuscan S. I had 2 extra Pioneer speakers fitted when I ordered it (4 in total).

Thinking of changing to a T350C towards the end of this year.

I've noticed the T350 only has 2 speakers like the standard Tuscan.

Can these be upgraded by the factory? If so, what options are available?
