I am in the middle of the second major overhaul of this car. I got it at 95k mi. in pretty good condition. I plan on keeping it till 200k mi and since i drive around 10k mi per year i'll have it a while.
PREVIOUS INSTALL
First installation had the following
- Alpine CDA-9851
- Clarion EQS 746
- Audio Control EQL
- Xtant 403A
- Massive Audio 6.5" Components
- Cerwin Vega VEGA124
I really liked the kit for this car, i did have to modify the EQ opening a bit.
Fabricated a bracket for the two so they wouldn't sag.
Too bad my dash illumination isn't blue.
Rear seat is locked in place (need the key to drop) so this was a secure place for the rack.
Covered it in vinyl to match the interior. The factory carpeted trapezoid opening needed to be addressed though.
The speakers were in factory locations, but nothing was deadened.
I tried several sub combinations but without deadening it was empty and resonant.
This was the previous sub
CURRENT INSTALL
Now I am running/installing the following
- Alpine CDA-7930
- Alpine ERA-G320
- Alpine 3672 Active Dividing Network
- (2) Xtant 403A
- Alpine SPX-177R
- Alpine SWR-1242
The head unit needs to be integrated into the dash better. I've painted all of the interior trim textured silver and now the plastic mounting piece looks stupid.
The sunglasses holder was removed and a mount made to hold the ERA-G320 display/controller.
Built the amp rack out of 2x4's and 3/4" plywood, painted it gray just because. Filled space behind rack and wheel well with foam
Amps are mounted in place of the side pocket on the drivers side. This keeps them out of the way. I need to build a frame that will flush them up though. This whole trunk is my next project that will go on while I deaden. I will customize the whole thing, sides, floor, rear deck, everything. I was using this box at the time for testing. I hated it facing backwards.
That box was for testing, the Type-R is firing sealed into the cabin now. It is centered, the pic is just at an angle.
Front Type-X comps are mounted as shown. I need to build a custom speaker grill for the door. I left the corner on so you have to remove the door panel in order to get the grill off, and thus the speaker out.
The angle mounts worked out pretty well. If I cover or do any changes to the apillars i'll make it match a bit better.
Type-X crossovers mounted in the glove box for easy tuning. Notice the Clarion EQ isn't in this pic. For a while I ran the 9851 with the G320. The sat radio piece works without a subscription so that's why it's not integrated (plus i like the display and control). I'd like to get that more integrated soon so it's not getting in the way of passenger's knees.
Did a first pass of deadening with the mids. I have more to go back and seal the doors up for good. I used a sheet of polyfill to put between the door panel and door. I ran out of deadening before I could completely coat the door. That is the next thing i'll do.
Also did some polyfill behind the driver siliconed to the deadened outer door skin (does not interfere with window).
The rear deck is pretty empty, I recovered it and removed most of the noise producing parts. No rear speakers.
WIRING
Some shots of the wire routing. I used split loom for easy wire additions and removal. It isn't secured to the car yet since I need to deaden the floor still. Currently it is secured in place with duct tape.
I used split loom the rest of the way but wanted a pic of the signal cables contained in the split loom. Passenger side has Ai-Net cable, two sets of RCA's, and four sets of speaker wire for the front components coming out from the rear deck opening.
At the rear seats the cables split, four sets of speaker wires down passenger side, signal cables down the center under the center console.
Driver's side has power wire, remote, additional control wiring, and bass shaker speaker wire.
DEADENING
Car being stripped. I drove around with the interior out of this car, drivers seat only, for about six weeks. I was deadening, test fitting pieces, listening for rattles, etc. It was funny.
50 sq. ft. of deadening on the trunk, rear deck. I still need to do the whole floor, roof, front doors again, door panels, etc. I have 100 sq. ft. ready to go now. I will probably use another 100 sq. ft. (and that will be one layer in most areas only).
I need to come up with a cover for the side posts. I left the factory battery posts in place. Woo hoo for dual mount batteries.
Grounding part of the Big 3

Pretty nice, was it hard to get the deadener on the other side of those crossbraces under your rear deck? Did you have to take the braces out?

the cross braces stayed put. i used several strips instead of one large sheet. I also had someone helping me keep it from sticking to the rear deck too soon. made things much easier.

Great install. Very clean.
I have one of those bass shakers mounted in my sofa for home theater... fantastic little thing. How are you powering yours off 12V?
Oh yeah, I remember a while back you mentioning something about a ported JL sub setup. Still thinking about that?

i'll have one of the JL dual 12 HO enclosures (grey with red insert)soon that i'll be getting to try out. it's pretty big so we'll see if it fits.
the bass shakers are made by Aura and are powered off one of the xtant's mono channel. they wire up just like a speaker.
those bass shakers give the illusion of very fast and quick sub response. attack and decay are flawless.

i think they sound good. i need to seal and deaden my doors better and then see what that does but i've got plenty of midbass with the partial deadening aleady. i've played with several tweeter locations and also adjusted the crossover many times. i've adjusted the eq and time alignment as well. i like where i'm at right now, but it's not perfect. it is improving over time though, which is nice. right now they get 200W from each xtant bridged. they play a lot clearer and louder compared to only 50W unbridged (no surprise).
the ring radiator tweeter is interesting. i need more crossover flexibility (to be added soon) in order to evaluate it more.
keep in mind they aren't expensive drivers. the replacement tweeters sold for $35, the mids for around $50. the crossover was worth more than the speakers.
with having only 5 drivers in the car (2 tweeters, 2 mids, 1 sub and not counting the bass shakers) it plays surprisingly loud and very clean. i have a few reflection issues and a couple resonance issues to address, but nothing major. the sound stage is pretty wide and i keep getting tricked into thinking i have rear speakers running, though i don't. instruments are well defined and easy to locate.

"That box was for testing, the Type-R is firing sealed into the cabin now. It is centered, the pic is just at an angle."
Hey Hope, how does that setup sound? How is SQ & SPL vs. rear firing sealed and the original rear-fire ported setup?
How does it sound if you put the seat up? Do you usually ride around with it up?
Right now I have a 12W7 ported & rear-firing, but its not as tight as I'd like. Thinking about replicating your current setup.
Thanks.

seat is always up, arm rest is down when driving. sub fires through arm rest.
rear-facing the bass was boomy and uneven. forward-facing it was better but a bit resonant. forward-firing with it sealed to the cabin it is very detailed, clean, and accurate.
I borrow a sound meter from work for different testing. it's only a 130dB meter so i pick a volume, leave all settings the same, then move the box around. i'll do a post with the different results sometime soon. it should be informative and helpful for others.
since i was more concerned with SQ sealed forward was the only option. i tried three different boxes for the Type-R. I have an aperiodic design to try next. everything is built, i just need to put it in.
