Hey guys i was just wondering about a few things. I'm planning on getting a pair of JL audio 10" subs put in the back. Before doin i though i just wanted to see what a box with similar subs looks like in the back. Does it take up too much room and how will it perform. Also i'm not much of an audio expert but the guy at the shop told me that i didn't need to change out my stock stereo unit. If i keep it stock will this affect the performance of the subs at all? Thanks for all your help. any pictures would be most helpful.
