I am doing this for a friend of mine....He has a '03 Civic and wants to take his two 10" pioneer subs out of the box and install them on the trunk floor like flat, facing up....I hope you all understand what i'm sayin....basically the lid on the floor that covers up the spare, jack, etc. Does anyone have instructions or tips on doing this...and how to take the negative/positive connectors from the back of the sub box and some how attach them to the subs so it goes to his amp correctly.....any help would be appreciated....Thanks!

 

You are going to have to get good with fiberglass to do this properly.

 

I do not in any way mean to be rude, but it seems as though with your knowledge, you shouldn't be attemting this.
