KF laser rear speakers?

[xespack]

Hey all,

Is there a stock place for KF laser to have rear speakers or do they only come with the 4 inch under the dash? If so where and what size? I just put a new cd player in mine with some new 4 inch pioneer speakers under the dash but it sounds terrible. Sounds like splits with only the tweeters working or something! I would like to put some 6 by9 or 6 inches in there somwhere if i can without cutting up the interior if i can help it.
