(View from the back seat, both the amp and capacitor were mounted on the back of the sub box.) Here is a little money saving tip for all you deal-seekers, shop for stuff on Ebay. They have both NEW and old on there, and plenty of it. Most of it is cheaper than what you would pay for retail. That is where I got my subs and amp. I payed $50 less per sub, and $35 less for the amp than I would have buying it at a store. They were brand-new, in sealed boxes, and they shipped for free. I have just started on the DynoMat project for my car. Eventually, I hope to have almost all doors, engine compartment, and trunk done. For right now, with a limited supply of cash, I was only able to get the deck lid finished. Even with that little bit covered, it has made a difference in the sound as well as a reduction in trunk rattle.
