Well i guess it seems easier to just use a box and put it in the trunk and not on the deck. The reason i wanted to mount it on the deck was to make it look as stock as possible and so that the sound would be channelled towards the interior rather than the outside (cars around me) . I'm still shopping for a subwoofer but i just wanted to know all the facts and installation instructions before i bought one. I'm a noob so just bare with me. Thanks a lot b00gers.
