curious alng ako. is there a way to use a 2DIN HU in place of the stock 1DIN HU?

what are the adjustments or re-fittings to be made? or a simple removal of the existing HU plus the box underneath it will be sufficient?

i have here kasi an extra 2DIN HU na maayos pa (came from a Nissan Cefiro). Eh yung isang oto ko (a Nissan Sentra SS3) needs to have the HU replaced dahil stock pa sya.

thanks.
