Goldwood GW-412D 12" Poly DVC Subwoofer
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.
All of the drivers in my car are Home Audio or Pro Audio, none are automotive audio, been this way for many years, works fantastically.Any input on a BandPass design would be much appreciated.

Are there two sets of terminals on this driver?
It would be replacing a Canton sub driver where two incoming channels connect to the enclosure. On the inside, from that terminal, two wires connect to the driver. Two more wires connect to different terminals on the driver, then to terminals on the cabinet that feed two channels for satellite speakers.

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.

How would this subwoofer do in a sealed enclosure?
This will perform very well in a sealed enclosure between 2 and 3 cubic feet.

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.

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.
