It rattles your car

 

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.

 

Cannot believe B&O using standard non branded make woofer.

 

You make it sound better and better.

The only thing that worries me now is that I might not get the same result because you had B&O to begin with, and I only have the 10 speaker Audi Audio system. I assume the stock amps are different?

I also changed my radio coding to "dynaudio profile" in byte 4, as I heard that it's the coding for B&O and it did massively increase the sound quality. However I also heard that in some cases with mmi 3g+ it disables the subwoofer adjustment through mmi or even sometimes disables the sub all together. I better check that first.

Do you happen to know anything about that by any chance?

 

Hey guys, I had a look at the enclosure but can't find the vented port that you guys are closing up. Can anyone point to where it is on the box?

 

Just doing mine today and it is at the end of one of the thin bits.

 

@andycparker would love to hear your comments. So tempted to do this myself.

 

I haven't had time to fully adjust the settings on the Mimi system but so far it does sound a bit lower and more punchy on most tracks. With the right music especially at higher volumes it does drop quite well..not night and day but better.

The lack of subwoofer adjustment on the Mimi system is annoying as the door speakers come in too much and cause door rattle but that was a problem with the older stock sub too.

For £109 and a couple of hours I think it was worth it for a neat upgrade and no loss of boot space.

It has not blown me away but I used to have 2 x 10inch subs in my old car with a separate amp. I didn't want that level of base or hastle this time so went for the Kicker upgrade.

 

@andycparker Thanks for the feedback. Did you block the sub vent to create a sealed enclosure?
Mmmm might be time to go shopping…

I had the port sealed but wasnt happy with the sound. I unblocked it today and changed a few settings and it is much better and what I had hoped it would sound like.

These settings worked for me to get a good bit of base out of the system without the door speakers rattling the doors.

Base 3/4
Treble just over half.
L/R Central
Fade Fully back to 1/4 forwards.
Surround 0 to 1/4
Focus All
Can't remember the last setting but put to off. This just adjusts sound depending on road noise.
Volume higher than normal.

For a bit less base you can slide the fader more towards the front position and use lower volumes.

 

Thought I deleted that first post.

 

I did it for you.

 

Thanks for the update.

 

Thanks for deleting. The instructions for the sub say N/A for ported but it seemed to restrict the speaker too much. I think because of the low power going to it from the stock amp isn't enough.

 

Yep, I left my port open too - found that closing the port reduced the bass too much.

 

love this i did this myself works very well!! subtle but a definate improvement!

 

Hi Elmo, 👋.

This is a fantastic post and something I would like to try if possible. We own a b8.5 rs4 but think it's the same as a s5 sport back audio wise etc.

Ours has the B and O setup and I will agree the sound quality is very good but it just lacks base.

We have the sub in the spare wheel etc so I think this I might give ago.

Are you driving this sub from the factory amp, so just plugging the new sub into the wires in the boot etc or are you running it of a separate amp for extra gain control etc?

Your fry the amp you needed to keep the speaker at 6 ohms
