I have just started the build for this vehicle. Equipment list is as follows:
Head Unit: Pioneer DEH-980BT
Front Speakers: Hertz Mille MLK-165 6.5"
Rear Speakers: None - Hertz High Energy HV165XL planned for future.
Sub: Hertz High Energy HX300 12"
Amp: Audison LRx 5.1k

This list of equipment is all purchased authorized from a local shop. Their prices are the same as online and they warranty directly. Cost of equipment listed is about $3300.

We also picked up 200st. ft. of Raammat BXT II and 200 sq. ft. of adhesive Ensolite ($800 total). The entire vehicle will be treated.

On to the pictures...

Factory Door - remove panel, remove all wiring clips, remove factory speaker, and clean all metal surfaces


Trace the factory speakers and make a new baffle out of 3/4" MDF


Mount using the factory speaker rivet holes and a 1.5" 10-24 machine screw and bolt.


Test fit before deadening


You can't let MDF get wet - deaden the baffle


Cover it 100%


but don't cover the mounting holes! :)



mostly deadened door - holes will be covered up next time and Ensolite applied.


you must protect the speaker from rain water. i use 3/4" closed cell foam weatherstripping along the top of the inside of the opening. gives the water a channel to follow AROUND the speaker.


then deaden the seam between the baffle and the door and over the foam




end result after mounting and deadening the front speaker baffle





We are using the factory speaker wiring for now, until we install the Audison LRx5.1k, at which point we'll run new 14awg wire to the amp/crossovers. I cut off the end of the speaker terminal, and extend the wiring to inside the door, zip tied to factory wiring the whole way - even inside the door.


Sexy Hertz Mille MLK-165 pics










mount the speakers in the door with the supplied hardware







repeat process for the driver's side




door panels installed, speakers tested for fit. foam was placed on the front of the speaker basket so it would seal against the door




factory door panel reinstalled.




Next we'll close up the door holes for a complete seal, and install the awesome MLK tweeters in the apillars.

Updates:

We are going with 2 Hertz Mille ML2500 subs in a custom sealed enclosure behind the rear folding seats. That Mille sub is amazing.

The Audison LRx5.1k will go along the drivers side rear trunk. it will be actively cooled and hidden with a panel for stealth.

We did get rear speakers - Hertz HSK165XL - the nicest high energy mids they make and quite a bit less than the Mille. perfect for rear fill. They will be powered off the front low power channels on the 5.1k and the Mille's will be powered off the rear high power channels on the 5.1k through that huge, beautiful crossover.

We also picked up Streetwires 1/0 and terminals, and several hundred feet of 12 awg speaker wire. all speakers will be wired with 12 awg.

We've both been busy for quite some time, but are getting ancy now that all the equipment has been purchased. We'll be working in stages, picking a week night each week. Our weekends are too busy.

Everything in the Mille line is amazing. I haven't heard one thing from it I don't like. I used to own that tweeter that comes with it. It is nice both on and off axis but is friggen AWESOME on axis.

Thanks Basher - we are definitely planning on-axis in the apillar. the owner wants it that way, aiming to be determined with testing.

We took another swing at the car yesterday, this time installing Hertz 165XL speakers in the rear. We discussed rear speakers/rear fill for several months. The owner is an experience recording engineer and knows what he wants and what he likes. He saves his sound stage reproduction for his mixing monitors. In this car, he wants a reference system that has tonal accuracy - which is why he chose the speakers he did.

This is the gear for the vehicle, minus the 165XL box since the local shop gave us the mids out of a 165XL comp set.



It is comical what they have in the rear of this car. Two thin pieced of sheet metal combine at this rear speaker location, the speaker is mounted to this flimsy piece of metal surrounded by open area - can you say "free air"? The seal created by the rear grill panel is very important.

notice the blue organizer drawer - i use that to keep track of screws - i don't lose screws/bolts or end up with missing or extra parts.








this is part one of this effort, so we focused on deadening the outside skin - two layers of Raammat BXT II.




While the owner was laying the deadener, I made 3/4" MDF mounting baffles






we didn't deaden all over the sheet metal because we may very likely cut away this thin metal to make way for a sealed enclosure. i don't like cutting metal that has deadener on it. for now, before we get the amp in, i just terminated the factory wiring. kinda silly to use this wire on these amazing speakers... all in time.



next i decided to fill some of this open area with thick open cell foam. i stuffed some large pieces up above the speaker mount - in hopes of reducing the back wave that makes it up and out by the rear side window

i fit this:


up here


then i just used an obnoxious amount of foam in the rest of the cavity, for now.



The Hertz 165XL is a nice driver






because the seal is crucial, i used thicker open cell foam weatherstripping





Everything reassembled:




He has the factory sub upgrade option, but not for long. The performance of this is awful

He has another $400 in wiring and accessories including Streetwires 1/0 kit, another random brand 1/0 kit for the big 3, and 250ft of 12awg wire, split loom, etc.


then we spent $110 at Menards on the everyday stuff I keep on hand for installs, he wanted to replenish what we will use


not pictured is Super 77 spray adhesive, Gorilla glue, Acetone, and some other chemicals.

I think this pushed his investment to the $5500 mark.

Looking good. I like the new High Energy speakers.

we will say this, if we had been able to audition the 165XL comps at the time, we probably would have went with them over the Mille. The new cone for the 165XL has a lot less break-up compared to the standard high-energy. the extra "warmth" you hear with the high energy is from a lot of tonal content and upper midrange distortion from the speaker itself. in this case, we just had the local shop part out the only 165XL comp set they had since there wasn't a time frame for ordering the mids only.

all of the BXT II and foam in the rear cavity has also greatly helped with road noise and eliminated the 125Hz tone the car had. Seriously, that rear sheet metal and cavity resonated at 125Hz constantly. It's a lot better now, foam does wonders. \:\)

Where did you find the foam just lying around? Where could i find some? I need a ton for exactly what you did.
