I can finally put the car back together!
In order to get the vents to fit over the tweeters, I ended up having to dremel away some interior bits of plastic on those pieces as well.
Here's what it looks like before being molested:
I had checked the amp/dsp firmware already, and it was up to date. I knew there was a firmware update available for the DRC, so I went to go update that. And the computer program said the update failed, and the DRC broke
It simply said "Erase completed"
Tried a different computer, couldn't even get all the requisite software installed on that one. Time to call my friends at Elevated Audio again. In the state in was in, they taught me that I could press the Escape button, and it would put it in "boot mode." They also admitted these things can be finicky, and asked if I could bring the car down so they can troubleshoot. Worst case, they have another DRC in stock that they could swap out for me.
That's what I did, I showed them what I did, we put it in boot mode, and tried to install the firmware again. Same results.
Tried on their shop laptop, and it worked without a hitch. Sigh. Well, at least it's up and running now. Here's where I decided to mount it. And with the DRC MP, you can choose between 42 different colors. Anyone want to guess what color I chose?
MOAR YELLOW, of course!!
After all this, how does it sound? I'm very pleased. It still definitely needs a subwoofer.
I was tinkering around with having one preset as my "2-way tune," and setup the other one as a "3-way," using the factory midrange speaker. I've got the 2-way tune about 90% there; the 3-way needs some more work. But that's just for frequencies and tonalities. Comparing the soundstage of the two is pretty revealing.
At least for this car, with the factory speaker locations where they are, I much prefer the 2-way. In that configuration, the tweeters are crossed lower (I'm doing 2250Hz right now), which raises the soundstage much higher. In my 3-way tune, I have the mids doing 500-3k; then tweeters start at 3k. 24db Linkwitz-Riley all around. And the soundstage plummets down to around mid-torso. I'll still play with the tuning, but so far, I'm thinking I'll just stick with the 2-way setup as per my original design. Not a bad thing, that means I can save money on not buying better mids!
