Interior Cleaning & Stereo Upgrade
I have been spending a lot of time on the interior of the car. Cleaning the interior plastics and upgrading the stereo system. The Bose system is a pain in the butt, and the RX7 is not very friendly to upgrade the system for good acoustics. My Bose system crapped out so I decided to upgrade everything at once. Luckily I have a friend in the Audio Business that helped design a well sounding system.
All speakers in the car are JL Audio products. Everything was done with custom brackets since this was a Bose car.
The front 6.5" components in the doors were done with custom fiberglass brackets to allow for the depth of the speakers.
6.5" Coaxial speakers were used in the rear with some MDF brackets.
The rear sub-woofer is a 10" W6 sub-woofer in ported box.
2 JL Amps (G Series 4500 - 4 Channel and 1700 - Sub Amp) pushing everything.
Receiver: Kenwood DNX6160 w/ DVD, Navigation, Bluetooth, Sirus Radio, IPOD, etc.
Viper Alarm w/ new actuators to keep everything as safe as possible.
I am very happy with the sound quality of the system. The car was heavily sound proofed with hush mat. The car doesn't rattle at all, and the sub hits very hard for a single 10" woofer. Since I am over 30, I had the bass **** installed to turn the sub down when it gets old!

Good job and nice install, I like how the amps are matching and visible, I also like the head unit. I'm not sure about the sound of the tweeters in that location though. They are too close imo. Also I'd cancel the coaxials if I were you. Listen to your system with and without coaxials and you'll know what I mean. I know cause I had coaxials in the back like many in this forum before switching to my current set up. Here is the link:

I only had the car for about a day before it went to the body shop to get painted. The car sounded leaps and bounds better than the Bose system, but that is not saying much! The coaxial speakers sounded good, but I could always change them to component speakers too.

What I mean is in the future when you feel like making little changes cancel any sort of rear speaker set-up (excl. woofer). Doesn't matter if coaxial or components. Im not trying to put you off your system, just sharing what I've learned in the past few months when dealing with my own set-up. For speakers a pair of quality components is all a rx7 needs and a woofer depending on personal choice

A view from another installer....
That box looks... a little big for just a 10W3.... You'd get lower bass, tighter bass and more defined bass tones if it was in a sealed - and much smaller - 0.5 cubic foot enclosure, which was my FD's prior setup. Boomy one-tone bass is the hallmark of ported boxes. If you're looking for music to be reproduced as it is encoded on the source material (CD, iPod), a sealed box is the best choice - plus they're smaller. My old box easily fits under the rear strut bar.
I'm thinking the tweeters were placed that close to try to achieve visual symmetry as the FD interior panels are very different in shape. However it's more important to achieve acoustic symmetry. In its current position, the left tweeter is facing directly into the side of the steering column, while the right one is unobstructed. And if he was going to cut up the trunk separator, he really should have had the sub compressing the cabin, not the trunk. You're not in the trunk to experience the sound pressure. Don't believe people who say that speakers sound louder when you face them away from you, or "bouncing" them off the trunk wall amplifies bass. Also did he propose a way to hide your expensive JL amps in that position? You probably don't want those just out in plain view.
Since you posted the pics, I'm just providing feedback. It might sound critical, and it is, but I'm sharing an opinion from the perspective of another installer. I'd give the same feedback if I was standing next to ya. Just some things to think about.
I will give credit in that, from the pics, it does appear he did a good job on the actual flush mounting of the tweeters.

That's nice constructive criticism.
I think the OP is really happy that it sounds better than the factory unit. I feel the same about my sub.

Like stated, this is night and day to a Bose sound system. It sounds great in the car. Heck, I am half deaf from being in the Army anyway so I probably wouldn't notice the difference if the tweeters were located in another position!
