Has anyone built this sub before? I'm confused on the supplies I need for this sub. I know I need an enclosure, a shiva driver, an amp and a flared port. On the Adire Audio web site they list a Sub-V sub kit which includes a port, biwire cap, 10' wiring, grille, and some other assorted hardware. Do I need this entire kit or do I just need a port? Does the AVA250 amp come with the necessary wiring to hook to the driver? Does the Shiva come with the needed input terminals to hook to the amp? I just want to make sure I have everything I need before I get started. Thanks in advance for any input.
