Goldwood GW-412D 12" Poly DVC Subwoofer
I have a 2.25ft3 enclosure. What port diameter and length would be good for this speaker?
A 3" diameter, 6" long port will tune this to 31 Hz.

Would this woofer work better in a Sealed or ported enclosure? I am using it in a 3 way tower speaker. Also what would be an ideal crossover point between this and the GRS 8PF-8 8" paper cone?
These will work best in a sealed enclosure from 2-3 cubic feet and heavily stuffed. It will handle a crossover frequency from 200-1,000 Hz, but generally a woofer to mid is around 350 Hz.

BandPass enclosure specs
I would like to mount this on a baffle mounted in the center of an 8 cuft car trunk. The baffle would run front to rear, the trunk would be the enclosure, I would seal the baffle so when the trunk lid is closed the front is sealed from the back. The trunk has two tunnels that run on either side of the fuel tank up to the passenger compartment. The tunnels are roughly 5" x 5" x 15" long. I can mount and seal PVC pipe into these tunnels if necessary.I realize this isn't optimal but the car is a Mazda Miata, there isn't any other space really. I do realize I will have to damp the trunk.Is there a better woofer for this application? I'm not looking to shatter windows, this design will be easily removable and actually take up less space with no additional box.
First, there are specific demands of mobile components. Temps up to 140 degrees and down below freezing are one, moisture and humidity are the other... Then - as you know - the car can rattle, and without tearing it apart to turn it into a cabinet - how do you get good bass? The Goldwood is not designed for mobile use. In the search field at the top of the page, type in "auto subwoofers" and it will appear as the third category with 4 different sizes. That's your starting point in selecting a mobile subwoofer

what is the max power input - hard to interpret the specs
SPecs call for 130 RMS 260 max wattage input. What is this saying? 130 RMS per coil with 260 peak wattage per coil? or another way of saying 65 RMS with 130 Peak per coil?
260 Watts per coil is liberal for a speaker at this cost. I would not exceed that rating in your power supply to this speaker.
