Got the Kicker in today and started finishing right away.

First the pictures from the post before:

The result after drilling the rivets out. (Done this over the sink so the pieces of metals from drilling would not fly around)

The massive B&O sound quality subwoofer driver, it still makes me laugh everytime I see it. ?

So now back to the fun stuff ? (I do not mean the B&O driver)

The Kicker subwoofer driver next to the B&O:

Preparing the box for the insertion of the Kicker:

You have to cut away some plastic parts for the woofer to fit:
1. The notches that keep the B&O centered, cut away with a utility knife or something else.
2. A little enforcements plastic thingy's (I have no idea how the are called/ named in English)

1. The result should look like this

2. This one is a little tricky, but if you are the proud owner of a multitool and are willingly to sacrifice a saw blade, just bend it so you can let it slide over the bottom of the enclosure

So the result will be a nice clean cut

Time to do some wire magic:

The Kicker has dual 2 Ohm voice coils vs the B&O single 6 Ohm, so we are going to wire it in series to make a single 4 Ohm voice coil

The result in the next post

The result of the wiring

I am still thinking of a way to remount the protection grill, if I think of something, I will share it.

Next is just screw it in, mount back in the car, select you music, open up all the gain and be amazed of the 90 euro transformation of your sound system. (I should have made a picture when it was done, forgot it in all my excitement)

It is the best thing I have done yet to the car.

Something I forgot to mention:

The manual of the Kicker has no given information on vented enclosures for this specific driver. I have closed the vented port of the enclosure with some foam and duct-tape.

Yes it does pack a great punch, allmost like a reverse capwearing 2x 15" subwoofer overloaded Golf 3 GTI teen car,...
My girlfriend allmost jumped through the roof opening it up.

The sub is then perfect.
Just be carefull when tightning the screws, the plastic is not that thick.

Found the speaker, is the 2x dual coil (comp RT672) preferable to the 1x dual coil (comp RT671)?

More importantly, after switching to 4 om from 6 om, do you get an error message on vagcom?

Also, do you have to remove the battery in order to get the cover out?

You are not switching from 4 to 6 ohm.
The original sub in mine was 6ohm, so i just wired the dual 3 ohm voice coils to 6ohm.

thanks for the write up. Followed your advice and it sounds loads better now. Only thing I found was that the speaker didn’t seal very well, so I used a cold melt glue gun fill in around. Very happy with the improvement.

Good to hear that I was able to help you!

Wire the voice coils in series to create an 4 ohm load. Can you post a picture of your subwoofer connections?

Hi John and Rhino,

There is a schematic in the first post how to wire it....

But if you missed it:

It is definitely worth the effort and cost to do this mod.

But for the option price of the B&O package, it already should have sounded like this.

Hi guys, sorry to revive this thread but its a really excellent write up. I am looking into a sub upgrade after i upgraded my door speakers and tweeters + added soundproofing to doors, and now the stock sub is not keeping up.

I am considering 3 things: doing exactly this stock sub replacement with the kicker sub, installing an active sub eg. JBL Stage 800BA, or going full out and getting a sub with a separate amp with an enclosure dedicated for the A5 sportback like below.

Each option has its pros and cons, costs, performance, space taken up, ease of install.

I am really tempted with the kicker, i would really appreciate if those of you that installed it in your cars gave me a more detailed description of bass improvements to help me make a decision?

Dear Lukasz,

It all depends on you, the Kicker will surprise you!
(Especially combine with Audison Mid Bass speakers in the doors) What’s the type of music you listen, get the crazy look from other drivers at a stop sign, but most of all: have you outgrown the “Backwards Baseball Cap Hoody Golf GTI” stage of your life? You are driving an A5. (No offence here, but after 10 minutes I just could not think of other words that would explain it more clearly.)

It rattles your car

 

[Elmo299]

i think you have me convinced!

I never even sat in a car with a proper 10" or 12" sub so i have nothing to compare against, but i know that i am after quality sound and not how loud it is. I think it should make me happy.

Just out of curiosity, what would happen if the kicker was connected in parallel? technically 2ohms instead of 4ohms means 2x current draw so twice as much power output?

I thought of the same, but there is zero to none documentation on the DSP Amp.

But trust me, I have build showcars for SPL (lets blow out the windshield and ear drums) contests and sound quality (every rattle or strange vibrations/ noise will set you back in points) contests. This works stupidly and surprising well, but I only installed it on Sportbacks.
