Nexus 5 Red display, battery door, loudspeakers topic

Hi guys,
First of all I would like to know some good sites with shipping to Italy where I can buy oem/original/good quality front and rear panel in red.
Also I was wondering if there is any loudspeaker aftermarket to put on!

P.S: any news on a battery replacement of 2800/3000mAh? always a dream :D

Thank you all!
