Well the garage is now cleared of the Vette I was working on, so it is time for a new project. How about my own Durango? Seems time, since I've had the truck about a year and I'm thoroughly loving it. There's not much research out there on this platform, though Bradknob did a fantastic job archiving/researching the Grand Cherokee version of this truck, the Durango is a bit different. In an effort to help as many people as I can as I go on my own building journey, I've decided to measure, photograph, and comment on as much as I can. It will take much longer but one thing I have with this build is time, so I say let's go for it.
First up, I'm beginning the exploratory phase. This front speaker panel / defroster vent panel pops out with minimal effort. I simply used a plastic panel popper, and this popped right out.
The speaker opening in the panel is approximately 2.8"
The sun sensor measures approximately 0.92" wide on the top.
And has about .69" on the inside mounting point
(I measured those in case I try to mount a tweeter in the same spot, and transplant the sensor to the blank panel below)
The blank panel measures about 1.42"
This is the center channel speaker
It measures about 3.43" in diameter
It is about 1.85" deep
The speaker's height from the mounting point is .33"
The speaker's mounting holes are almost exactly 3.9" from each other, center to center.
The speaker's magnet diameter is 2.38"
The speaker mounting depth is only 1.75"
The area under the speaker is very cramped!
Just for fun I tried placing a CSS 4.5" midrange (the VWR126), and was immediately prevented from placing it due to the magnet not fitting in. I didn't expect it to "work" but I did want to see the first place I'd get stuck. I think I could put a shallow 4" driver in there but with the speaker opening only ~2.8", it clearly would not benefit from a larger diameter. However, just looking at it, I'd say maybe a very powerful ~3" driver could do the job, like the Fountek FR89EX 4ohm https://www.madisoundspeakerstore.co...l-range-4-ohm/ or the GR Research LGK 1.0 LGK 1.0 which has a mounting depth of 1.75", so it would clear with a mounting plate. Another option could be a Scanspeak Discovery 10F, for instance. Of all these, I've installed and used the FR89EX and it is a great driver.
