Need Help with building a custom speaker setup. Desperate help needed

[Maximo289]

Hi guys well I should have posted this ages ago and I don't know why I didn't.

But anyway im build a set of custom speakers for my GCSE (in the UK this a qualification) in product design. So anyway my problem is I don't know how to run my NVX NSW104 and my NVX NSP65 outside of a car so there's no battery or metal to ground too.

Any help would be extremely appreciated.

i have nearly finished the box and its tuned to 30hz with an open design.

EDIT: i dnt yet have an amp or anything else just the speakers, woofer and box
