Hiya Brian,

The subs in my post are 2ohms per coil (DVC) as specified by the manufacturer. I did not personally test the resistance across each coil. I did hook one up to the stock amplifier however and it was very well powered. The surround and cone were moving a considerable amount consistent with the expected resistance across each coil according to the manufacturer.

HOWEVER... sigh...

After spending many hours designing/making MDF brackets so that these big boys could be mounted, I have pretty much given up. The issue with mounting these speakers are their large magnets and slightly deeper design.

1. They cannot fit in the stock brackets at all, even with cutting because they conflict with the metal of the car. Also, if one were to cut the metal of the car and the brackets to make the speakers fit, it would cause the subs to be unenclosed causing a large loss in decibels.

2. Even with brackets, the magnets interfere with the metal openings in the car which need to be modified even when attempting to mount the woofer facing the seats. Also, this method will reduce the effectiveness of the woofers in the first place (forward facing = ). Also, I found when trying this method that you would have to cut the carpet right at the corner in which it bends to extend to the door, making it a tough install. Not to mention that making the brackets is a tricky business and requires a lot of time and thought.

I'm SUPER bummed by the results of the project. My general thoughts are that someone (with more experience than I) can likely make these speakers work in that spot while making them look good and sound good as well. I am positive they are a perfect match for the oem AMP so hopefully someone else eventually figures out how to squeeze them in.

well.. now to build a box for these puppies and stick em in the 1987 Grand National!!!
