Fake Woofer Delete - Kicker 6.7 Subwoofer Install

[Squandeezie]

23 Black diamond SAS 4door - Purchased with the passenger side fake sub woofer - Installed the kicker 6.75 like many recommend.
Total cost: $254,
KICKER 48CWRT672 CompRT 6.75- $104
FOMOCO FP5T-18C808-AB $75
OBD LINK EX -$75 (69 plus shipping)
If you already have FORscan total $180

The fusion amp is readily available from OCO industrial website - eBay had a lot of the fusion amps with the wrong harness sockets! The fp5t is the right one !!
Everything was plug and play - I added some rock wool to the enclosure and on the outside jammed between items to dampen things a bit. I added a diy foam gasket to the plastic speaker ring. Small amounts of weather stripping added for vibration on the side panel as well.

As a first time FORscan user I needed to get the new firmware and install a driver to my laptop , ** the link EX did not identify the bronco before downloading those.

BEFORE AND AFTER SOUND
Both recordings - Volume 10, recorded from center arm rest- no EQ change.

Critical: Small amounts of weather stripping added for vibration on the side panel as well.

I also plotted frequency response graphs of the before and after recordings. Amplitude of the 50Hz range is MUCH greater after.

There has been alot of discussion about whether to use the KICKER 48CWRT672 (2 Ohm) or the 48CWRT674 (4 Ohm). How is the 2 Ohm working out for you?

 

[Squandeezie]

Both of my terminals on the speaker have the label two ohms written on them, wiring up the speaker with the factory terminals I assume it's like a 4 ohm load that the amp will see. Since I am hooked to all 4 prongs.
I didn't tear apart the harness that feeds into the amp but I'm assuming there is a bus on the inside that makes the speaker in the series configuration in this diagram. Because if they were parallel I'd be BLASTING with only 1 ohm resistance.

Crutchfield says the 48CWRT672 has dual 2 Ohm voice coils. Here is a link to a discussion comparing the 2 Ohm and 4 Ohm coils:
