My car is 2005 Aveo 4 Door Sedan, I just bought a Pioneer DXT-2569UI it contains head unit with 4 speakers, 6.5 & 6x9. I bought the spacers to install the 6.5 in the front. Now Im trying to figure out how to install the 6x9 in the rear.

How can I "hack" the deck to install these? Id rather not buy anything extra, however if I can not get it to work Ill just buy 6x9 boxes.

Any suggestions? Did you guys ever figure it out? Iev searched for about an hour but found no instructions, I am writing this as last resort. Thanks!
