Sub question

RonRizz

You will not need a Capacitor, nor will you need to upgrade your alternator. I am currently running 4 amps (for years now) and have no issues whatsoever. 2 are 300 watt, one is 400 watt, and one is 1000 watt.
If you value your hatch space, go with a sealed box.
a single 12" sub will have more than enough punch for anyone in the Z. Average box volumes for a 12" Sub are around 1 cu ft, although there are a few shallow mounts on the market that will work in 1/2 cu ft.

Sorry if I was misleading; I didn't mean to say OP needed a new alternator. I was just saying that if someone is at the point where they think they need a capacitor, then what they really need is a beefier alternator.

This is good to mention. When I upgraded the system in my expedition, I replaced the (shitty) factory Bose sub with aftermarket. It's mounted in the sidewall between the sheet metal and the interior plastic trim. To get something aftermarket to fit into that space, I had to get a special low-profile sub for an aftermarket enclosure. It was tidy, but it was NOT cheap.

Thanks for the response everyone.. I think I'm down to (2)-10" subs or (1) - 12" sub... I called a shop today and they tried to sell me the JL Audio box built for the 370z. The damn box and subs are $1,000 though~! I think I'll go with a Zenclosure.

Appreciate everyone's comments~! I'm ready to rock....

$1k?! Is it fiberglas?
I wonder if there would be much demand for making fiberglass enclosures... Tailored to each specific sub

CrimsonTide

Yes dts ~ it's fiberglass.. This is the box:

Is fiberglass that much better than MDF? I don't know if my ears could tell the difference...

Fiberglass is of course much lighter and can be molded to shape, which is important for wheel well encloses. On the flip side, the second most quality determining factor for sub enclosures after volume/dimensions is the rigidity of the material... Flex=bad. MDF wins there. Fiberglass for a single sub setup in a Z will be more than enough
