Page 1 of Advice needed! Toshiba 32 D/D

I have a D/D tosh 32" which i am happy with, i am looking for a bit more
of the cinematic experience, i was thinking of buying a home cinema kit to bolt on?. The other option is to upgrade the rear speakers, and buy two new fronts, and keep the same intergrated sub woofer. Would that make a difference??

Can anybody help ?, any advice greatly recieived.

Cheers

Mark
