MKV Golf GTI - Semi SQ Audio install (pic heavy)

[GLIDN]

Hey Guys,

Been a few years since I actually posted up a build log. Only really been adding to build threads or gathering more information.

I have to say a big THANKS to DOITOR on diymobileaudio.

As he has also acquired a MKV golf and asked me a few questions.
Seeing I work on MKV's almost on a daily basis, mainly performance thou.

The idea was sparked.
So I'm finally building my own system!!!!

Here is my Setup

Head Unit : Factory  VW RCD510
CAN Translator - For Remote / ACC duties
EQ : JBL MS-8 (if it still works)
Front Setup : Hertz HSK 163.4 All Active
rear : stock (if I connect it)
Subwoofers : Image Dynamics IDQ10v2D4 (BNIB)

Unsure -
Amplifiers: This is where I am a little stuck
Soundstream Nano TR680.4
E-Audio 480AB
Audison SRX 2 (channel 80 wrms x 2)
Rockford Fosgate PBR300.1
JL Audio 500/5

So this is where I'm stuck. Either use my 500/5 for sub, Tweeter and mid's.
Then use my 480Ab bridged for 380wrms for the Midbass. Leave rears disconnected.

or

TR680.4 for tweeters and mids, 480Ab for Midbass and PBR300.1 for the sub

or

Go very simply with Passive front end running off of 2 channels on the 480Ab and the 2 rear channels in 2 ohm load for each IDQ leaving rears disconnected.

If any of you have suggestions/recommendations? By all means post them up.

Otherwise lets get onto the interesting part of the thread.

First weekend of build log,

some Gear

Image Dynamics IDQv2D4 - Just opened the box for it's first OOBE


EAudio 480Ab - It's a little grubby, not yet had a chance to clean it


RCA LOOM - start of OEM VW RCD510 Radio low level


Subwoofer box - Well start of



IDEA 1


During Fibreglassing



Popped out at 8:30PM tonight


I have already cleaned the excess tape off and letting it fully cure tonight.

The sub box will be 1ft3 Sealed for both 10's. In previous cars I use to run IDQ's, I found them best around 0.43ft3 per sub. So I may yet drop down to 0.9Ft3.

I have not yet decided if I create a removal top plate for the sub box.
This would mean I could run my single IDMAX10v3D4 inverted in the sealed enclosure for shows.

That's all for now. As I progress with the rest of the system I will post more pictures and info.

I think I might stop at this point.

Well where to begin? Losts has changed from my last update and most of my amplifier selection.

So let's begin......

I had to rebuild the top baffle board as I JUST did not have enough internal space. It was calculated to approx 0.86ft3 but really wanted 0.96ft3. So How do we fix this?

Simply really rebuild the baffle plate again. Here you can see me cutting subwoofer mounts.


The router in action


Which lead me to this.



It so happened to reveal, none of the gear I wanted to use would fit even remotely. So did some head scratching and some new amplifiers were chosen and a few ideas have been laid out.

So I ended up with the following amplifiers to run the system.
1 x JBL MS-8 ( located under front seat
1 x Rockford fosgate PBR300.4 (tweeters and mids)
1 x Rockford fosgate PBR300.1 ( IDQ's 330wrms @ 1 ohm)
1 x Soundstream Nanoblock 680.4 (bridged for mid bass)
 Approx 240wrms per mid bass





Let me know your thoughts on the angled layout or simple straight lines??

I forgot to take some pictures while building the rear board for the subwoofer box, but this is where I ended the day well perhaps nights? Seeing it was 12:30am by the time I called it a night.

Here you guys go.

Looking forward to seeing this done. I personal like the amp sitting on the angle

I did as well. But it turned out I just did not have enough clearance for that.

I have also incorporated more parts in that area. So will post more tomorrow.

[GLIDN]

got some more done this evening.

Cutting a few boards up. I have started getting a possible idea together for a removable top plate. Will reveal the information over the weekend when I had a chance to test the theory.



Nice and skinny subwoofer box



Man forgotten how nice the V2 IDQ's where built


Finished off with the first prototype top plate this evening, It's currently an 18mm Plywood board. I will double stack the wood with an additional 14mm fibreboard wooden sheet. Which will also have a bevelled edge to allow the sub to be flush mounted.

Looking good but personally I would change the h/u to get better balance over the sound and adjustment

Ecco this... although I kept my OEM headunit and used an audison bit 10 DSP. It completely transformed the sound.

Originally I just installed the JL HD600/4, Hertz HSK 163 and JL 10W3V3 running from a AudioControl LC6i which is just a line out converter with bass level control. But I wasnt happy so tried the Audison in place of the AudioControl and it gave me so much more adjustability and completely changed the sound to more like what I was expecting from all the new hardware!

Yeah I feel the same. However, having put it all in with MDI and OEM Bluetooth etc.
Going after market, I just have not found a BT solution that's good enough on aftermarket that works theu the radio's RCA out.

Plus I'm not a fan of Double Din aftermarket units. Which makes it so much harder.

I'm using a JBL MS-8 as my alternative to an Audison Bit.Ten.
As much as I like the Audison. I had this laying around.

Will post a quick shot up later on, what I did in my previous MK5 GTI.

Will be testing the JBL tonight otherwise I will have to swap the EQ out for something else.

Next round of updates guys

I have heaps of photos to add. Which will happen later today.

In a nutshell, box is built. I had just too little airspace for the subwoofers at first.
Now rectified none of my normal sized amps even remotely fit.

So this is the final run down for the amplifiers

At this stage still using OEM radio, however I might stick my alpine 7998 in as the source.
1 x JBL MS-8 ( located under front seat
1 x Rockford fosgate PBR300.4 (tweeters and mids)
1 x Rockford fosgate PBR300.1 ( IDQ's 330wrms @ 1 ohm)
1 x Soundstream Nanoblock 680.4 (bridged for mid bass)
     Approx 240wrms per mid bass

Here are two ideas for the amplifier layout as a teaser
Angled amplifiers - ignore mounting post, they will be hidden or Perspex


Straight line - sorry tried rotating photo a few times


I'm going to try and hide as much of the
Cabling as possible.

Following.

And yes fit an aftermarket HU.
Have you seen the Pioneer ones? The one I have looks very good and I swore I'd never get an aftermarket HU owning a Mk5 for nearly 4 and half years now that takes some change!!
My bluetooth works wonderfully get in the car automatically sync can dial and browse phonebook on screen what more do you need ;)

[GLIDN]

Created the rear part of the baffle board well at least the lower part that is.

Here you go.


Will update and post more photo's once I get the rear plates built.

I did see the photo you posted in the other thread.
The issue I see here is that your Pioneer radio over here, cost more than my RCD510.
Plus my MFSW will have to work as well. As I installed all this into my car.

Will have to see how the JBL removes the dips and bumps first.
If it becomes a headache. I will swap the radio.

[GLIDN]

Got stuck back into my car on Friday night and worked thru till 5am the following morning.
Progress was slow due to finding out the hardway that only
The speaker level outputs only can be used.

The radio being used


The rear lid just about completed.


The window to the heart of the system cut


Then just some wiring I have done.




For those who are interested that silver box is the 9w7 premium Bluetooth unit.

That's all for the time being I'm afraid.

Yesterday I took the day off and installed some coil overs.
Today is pretty much a write off as well for the stereo.
Doing a full detail on the car today.

Excellent job..Know what you mean bout the bloody cables
