I took mine out as soon as i got it. Just toss some plugs and plugging tools, and a bicycle pump in there and you're good. 24 lbs gone... Plus i put my battery back there, nice and stealthy. Cut the foam insert to fit around the battery and bam, done. Matter of fact there's already a nice grommet in the spare tire well to run your cables through and under the car (ran my cables under the car as opposed to through the interior, for better serviceability, ease of maintenance/modification).
