Pioneer double din in my 2011 aveo LS

hey guys this is my first post here and i currently own a 2011 aveo LS
i want to upgrade the sound system and was wondering if the pioneer avh-1400dvd would be able to go into the current stock dash set up.

heres a link to the stereo: AVH-P1400DVD - 2-DIN Multimedia DVD Receiver with 5.8" Widescreen Touch Display and USB Direct Control for iPod®/iPhone® | Pioneer of Canada - English
im also looking to put in a second amp for the speakers in the back seats cuz i'v noticed that they dont go as loud as i want them to be lol also i know im prolly going to replace the speakers also was wondering what would u guys recomend for speakers and low watt app for rear speakers my budget isnt that high maybe 400 for new speakers and like 300 for amp i dont know what all the tech stuff so if u guys strongly recomend something ill prolly look up some reviews on them and mostly purchase them

thx for the help guys

I have it in my 2007 and love it!

go amazon.com
you can get car audio for cheap...

they even have boxes there, free shipping too

I would be interested in your factory head unit if it has mp3 cd and aux in. Thanks
