crack in sub + box in back seat

[BeAlLsTaR13]

its just a little one in the cone of my CVX, i thought it was just maybe a pencil mark or something weeks ago when i noticed it but i removed the set up today due to some sound deadener im getting this week

and i looked closer when i pulled the subs and its a crack

think one like this is/could be effecting anything, just curious.. heres a pic:

it goes from the bottom tip of the emblem down about 1.5"

also, im getting my secondskin tuesday, but wont have time to install until sunday fail.

today was the only day i had off so i removed everything today, if i removed it sunday i wouldnt have time to take everything out, install SS then re-install until the following friday (dont have time for shit) so i decided to take it out today so i can install and re-install sunday

to not have my tunez is like being shot in the left nut it sucks so bad, especially when your used to it

would it be fine for me to strap the box down on my back seat for the next week? might be noob question but curious, it can also give me an idea of how it would sound if i turned my box around and sealed it off from the trunk (since thats what im considering doing.
