accord

Hey, whats up?

I recently got a flat and my subs were blocking my spare. So i just pulled my subs out of my trunk stuck it in my back seat and went on. My problem is i have a 2000 honda accord and I dont know where to put my ground wire. Ofcourse one end is to the amp but i have no clue where to conect the other end. and I dont remember where it was before. If someone can provide some feed back thatd be great. Thanks to any and all replys
