Title: MKS sub with pictures
Post by: Scott4957 on June 12, 2016, 03:09:53 PM
Finally pulled the trunk apart to see what was in there. Its a 10" sub, dual 2 ohm voice coil free air. The cover makes a bit of an enclosure but is by no means sealed, in fact it has a bunch of holes in it. I measured the opening and it is exactly 10 inches so it should fit just about any 10 inch sub as most are under 10 inches for the hole. The stock sub is dropped in from the top which means I have to figure out how to pull the rear deck apart, that sucks. Once I get that apart I will likely mount the new sub from the bottom so I don't have to deal with that again. Here are some pictures.

Thanks!  Are my eyes deceiving me or is that the smallest magnet on a 10" sub of all time?

Looks like a really, really well braced deck though.  I bet that thing could handle a more serious subwoofer. 

Can you tell yet if the other speakers are isolated from the trunk?

They are, I can't even see them.

The sub magnet is probably neodymium, which would explain its small size.
The opening where the seats would fold down looks identical to the SHO.

Wow!  Looks like if I want to stick with my idea of just replacing the factory speaker to see if I get an improvement, I have very limited speaker options.

Searching for a 2 ohm, DVC, 10" sub that is free air capable I've only found one suitable candidate.  The Kicker CompD 40CWD102. 

https://www.amazon.com/Kicker-40CWD102-CompD-inch-Subwoofer/dp/B00BGRMCI4/ref=sr_1_1?s=automotive&ie=UTF8&qid=1465766416&sr=1-1&keywords=40CWD102 (https://www.amazon.com/Kicker-40CWD102-CompD-inch-Subwoofer/dp/B00BGRMCI4/ref=sr_1_1?s=automotive&ie=UTF8&qid=1465766416&sr=1-1&keywords=40CWD102)

On the bright side, it would be the cheapest sub I ever bought. LOL

Are you planning on using the factor amp? If not you can use any combo of ohm/voice coil.

I am considering the idea of just installing an upgraded speaker and seeing if it meets my needs.  Figure I could add an amplifier later if it didn't.

Being a 2ohm DVC sub though makes that a little harder since it limits the choices.  Plus, if I decided later that I wanted to add an amplifier, I would need one that is 1 ohm stable I think?  Been a while since I've dug into this topic.

Post by: glock-coma on June 12, 2016, 07:06:15 PM
You could go 4 ohm or 1 ohm with dvc 2 ohm sub.

I don't think you'll  notice a huge difference with just a different sub.  Not sure what the sensitivity is on the factory sub but the kicker is 86.2 db.

I had a heck of a time trying to add a sub to the exisitng THX system which ended in me finally scrapping the addition. The factory AMP is a complex piece and trying to use a clean sweep to get a l ine convertor added didnt work either. Outside of replacing all speakers and factory amp I saw no other way of adding some wanted punch to the factory system. Id like to see how the sub replacement turns out since I didnt explore that route, im subing to this thread :)

TX, i'm surprised you had so much trouble. Everyone seems to have had good luck using the LC2I to pull a signal off one of the speak outputs. I have placed an order for everything I need, the LC2I will be here tomorrow, and on Wednesday the Rockford R500X1D, Kappa 120.9w "went with the 12in" and a wiring kit. I will start with a free air/IB setup first to answer the question of whether or not it will work well. If I don't like it I'll build a sealed enclosure that will mount to the bottom of the rear deck.

I'm guessing the wiring diagram is different from the Sony that is posted. If anyone knows the best wires to tap for the LC2I please let me know, I assume I will only need one pair running mono. I also assume you need to tap the outputs from the amp to get vol control?
Title: Re: MKS sub with pictures
Post by: TX MKS-T on June 13, 2016, 10:50:16 AM
Yeah same hear having wired numerous systems but the THX setup is a whole other beast. I used the same line convertor your going with as well. I ended up pulling signal coming out of the amp but had no volume control off it and no other wires offered signal. Your 13 could be different though, fingers crossed you succeed though !

Oh and I researched for hours to locate wiring diagram for the THX and its like hush hush to find anything on ours.

Oh fun, that doesn't give me the warm fuzzys. I would think worst case you could pull from the existing sub leads, not sure what the range is. It is usually avoided so you can get a full range signal and let the LC2I do the work.
Title: Re: MKS sub with pictures
Post by: glock-coma on June 13, 2016, 10:57:51 AM
I would try to tap the rear door coaxial signal for the sub. That way you can set the crossover to your liking and not be handcuffed by the facp try rear sub signal.
Obviously you'll have to get a wiring diagram for the factory amp.

Hmmm, maybe Kevin can get that for me. I guess worst case I can pull the rear door panel and look at the wiring. Need to make sure I get the polarity correct as well. My concern with the sub output is bass roll off, though the LC2i can handle that as well. I have no idea what the cross over points are either. Its just super easy to get to so it would be nice if I could use it.
Title: Re: MKS sub with pictures
Post by: glock-coma on June 13, 2016, 12:10:58 PM
The lci2 has bass restoration so it will compensate for any factory roll off.
You can try at the sub wiring for the signal, but only use one set of +/-
You might be fine with the factory xover. 
Title: Re: MKS sub with pictures
Post by: Scott4957 on June 13, 2016, 01:05:46 PM
Yeah, I wish I had the tools to test and see what the output is. I sent Kevin a PM to see if he could pull the information at work. I will share with the other MKS owners if or when I find the best way to go. TX, i am wondering if maybe you had the polarity wrong when you tapped the other wires but did not get a signal. I mean there would have to be a signal there, from what I have read, if you had the polarity reversed the LC2i would not output any signal.
Title: Re: MKS sub with pictures
Post by: BiGMaC on June 13, 2016, 03:33:59 PM
Any time I do work on my stereo I use a CD with polarity clicks to check and also one to evaluate phase cancellation. Easy peezy, even though an RTA makes the latter easier to fix.
Title: Re: MKS sub with pictures
Post by: glock-coma on June 13, 2016, 04:56:31 PM
Also the signal should come AFTER the factory amp in the trunk. Some people say that a completely flat signal is obtainable it you get the signal out of the head unit. I have not confirmed this either way. But Im pretty sure you loose all sync functions and volume control if you tap before the amp.

Good luck...I have all the parts I need for the install (sub, amp, wires, line out converter, etc.) but haven't gotten around to the install yet.

Hoping this goes easy for you so I can build up the courage to do mine!

I have a ported box, that I was using in another car that I'm planning on using in my MKS.

I have a Rockford Fosgate P3D4-12 12 inch sub, along with an LC2I 2-channel line out converter.  Amp is a Kenwood KAC-8105D mono amp.

So really all I have to do is get the power wire from the battery to the trunk, and figure out where to install the line out converter.  I've read a bunch of posts on here, and even looked around on my MKS...and honestly, it seems like a pain the the ass!

Title: Re: MKS sub with pictures
Post by: sholxgt on June 14, 2016, 05:58:20 PM
I had it easy with two cars I've owned.  Not as easy with others.

The Crown Vic Police cars have a power distribution block in the trunk.
The Oldsmobile Aurora's have the battery under the back seat.

I think with the MKS/Taurus we are stuck with running a power cable all the way back.

Could have because after day 2 of probing wires I was pretty fustrated and threw in the towel. I did get a nice clean signal after the amp on 2 wires but lacked volume control from headunit. Also if it helps the power wire for the LC2i I ended running from the rear power port on middle console assuming the late model has this still like my 2010.

Yep nothing in the back that could be used for power on my 2010 so ran all the way up front. The frewall is pretty sealed so ended up even though I didnt want to drilling a small hole below the steering shaft and used a rubber groomet and ran wire through followed by sealing around it with silicone. The wire will poke out right behind the firewall heatshield and slightly below brake MC.

I am just going to pull the power for the LCi2 off the same run for the amp. With the GTO feature the LCi2 will turn on when it senses audio on the tapped speaker wires and off when it does not. Then you can use this to turn the amp on and off. I'm afraid that was time wasted. Its odd that you got a good signal after the amp but no volume control, I'm inclined to say you likely tapped the signal prior to the amp. Its pretty cut and dry, after the amp, the signal has to rise and fall with the volume knob and the LCi2 working properly has to see that. From my brief look at the amp it was not very clear what was inputs and what was outputs so I can see this getting confusing. As for why some of your taps got you nothing, that's hard to say. Its possible that you tapped a run to a tweeter and the bandpass is in the amp. This would mean the signals going down those wires where too high of a frequency and there was simply nothing in the range of the bandpass filter in the LCi2 to pass to the sub. This is why we need a wiring diagram for the THXII system. I know someone bought the one for the Sony system for 11 bucks, for that much I will just buy it if I can find it. I have a PM out to Kevin to see if he can get it for us but I have not heard back.

Let us know what you find to be the best way to run power from the battery to the trunk.  On other cars I've owned I was able to splice into a factory grommet and run along factory wires.  This car looks to be more sealed up than most.

I have everything mounted. I made a quick mounting plate for the amp and some concentric rings for the 12" Kappa to fit the 10" hole. I also found these wiring diagrams from a pre-2013 MKS THXII system, hoping these are similar. I made the mistake of not checking the sub wiring colors so I will have to pull the sub and reach up in the deck to pull it out and see if it matches these diagrams from the older system.

If I knew those diagrams where good for the 2013 I would pull from the rear door. I may start by pulling from the sub. I have downloaded a few free apps that will generate low bass frequencies 1hz-200+hz that I can test with to ensure the full range is being passed to this sub which starts at 23hz.

Another strange thought occurred to me...

I wonder if there's a way to disable the Active Noise Control?  Partially because I don't like the idea of the entire concept, but also because I'm wondering what happens if we change the speakers, tap certain lines, etc and leave it enabled. 

The brochure for the MKS says that the system will "channel acoustic adrenaline to you in the form of tuned engine bliss."

We don't have a sound symposium thing on the intake, so that leaves me guessing that it tries to make engine noises through the stereo?

Hmmm, not sure. I know BMW does that. I don't see how it will interfere with this type of setup. I found another MKS user on the board who used one of the 2 sub pairs and put them into his LC2i with no issues. He thinks the LPF is 100-120hz which is fine. This is where I will start and then test with an app to see when it starts passing to the sub. Listening to the THXII system without the sub for the last week has been interesting, you can really tell this is a well made system. I know some have said that past THXII systems have been better but this is by far the best factory system I have heard and I have no plans on messing with the rest of the system, just want some extra boom!

I came pretty close to buying the thing despite the anemic 5.4 just because the interior was so nice and the sound system was insanely good.

Definitely!  Much better set on stereo to my ears.

I also have the treble actually below center.  Gets too bright for me.  Which does leave me thinking that it mostly needs low fill...lots of it.  I think you are on the right path.

Good god its finally done! Something to consider if going free air in the rear deck "MKS has the 10" hole" You WILL need to remove the sun shade, that thing rattles like F'in crazy, no fixing it. It sounds pretty good, still need to tune it. I will have to dynomat the back deck and I may add weight to it as well. I placed 2 10# plates on closed cell foam, on on each side of the sub and it helped some. I will likely dynomat it first then see if there is a need to add weight.

Whats the least expensive option for dampening material?

Whatever you use just make sure it's buytl rubber based not asphalt.
If it comes in a roll it's asphalt based. It will literally melt on your rear deck and turn to liquid filling every crack and crevice with tar.

Also what you may be hearing is the rear deck cover vibrating, if you remove it to sound deaden I would use some sort of closed cell foam as decoupling from the deck to rear deck cover. I've used yoga mats for this purpose but you'll have to attach it somehow for full effectiveness.
If you have an Eastwood tool company near you you can save on shipping, that's what I used. For the price of dynamat there are other options.

Second skin is expensive but it's probably one of if not the best.
Plus a they sometimes have "B" stock that you can get cheaper.

Awesome, thank you! I left the rear deck off for now, all other pieces I reinstalled. So I guess that roll of window sealer is out, I figured it would smell so I didn't do it.

Man I wish that I could hear the end result!

When I did my last car I used Dynamat Extreme bulk kits.  Buying them on eBay, Amazon, etc I saved quite a bit.  Good thing since I used a lot of it.  Did every inch of the interior, roof, inner and outer doors, etc.  I'm sure there are cheaper alternatives.

If you don't have a roller, I suggest picking one up.  They make it easier to get it completely down quickly.

Post by: BiGMaC on June 18, 2016, 11:25:35 PM
If you use dynamat complete coverage is not necessary. Cover the areas around the sub and immediately beneath it... The just try to apply strips evenly to cover 50-60% of the inside of the trunk. I recommend you consider downing the seat backs in the trunk to focus the sound into the cabin. Remember the weight you're adding and consider how products like dynamat work....mthey absorb vibration and radiate the energy as heat. I was never unhappy with it... Don't pay retail and use the extreme version as it is dormulated to stay adherent to the underside of horizontal surfaces such as the roof, hood, trunk lid, and rear deck.  Good advise on the material to stock the deck "carpet" from buzzing. Keep going until you are sure it is exactly the sound you want... Looks like a great start.
As far as the rear sun screen...  I have never used mine except to verify function when I took delivery... You won't miss it.

I completely agree that complete coverage is not necessary in this application.  I was merely saying what I did when working with an import with a serious sound system.

In this application, I would only use the sound deadening/insulator to stop rattles and focus sound.

The front windows in my MKS are all marked "SoundScreen."  It is very quiet in the car.  Do the SHO's have "SoundScreen" glass?  Not sure if it makes much of a difference, but it sounds like a neat feature.
