How To - Setting Helix DSP's Input Gain & Input EQ Using Its Input RTA

C63S AMiGo

Wow... I’ll have to check out those videos after dinner. I am not skilled in tuning so I’ll be using the Fix to flatten everything out.

Man, signal processing GM an get real expensive real quick.

are you going to run any subs in the truck?

benzdude

If you get the JL Audio Fix 82 make sure to update the firmware first thing.

I have a JL Audio ACP208LG-W3V3 microsub + in the trunk.
Fits perfectly.

C63S AMiGo

Thats the subs I wanted but I measured the trunk and not sure it fits (Coupe). That area pinches in just a little at the top. I’ll make a cardboard template to double check.

I spoke with Morel yesterday and they stated they are coming out with a W205 specific kit early 2021. I initially called to get an opinion on using the Virtus Nano Carbon 3 way but my thoughts were confirmed that the mid is too small (2.5”) and that you’ll lose too much of the upper end of the 6.5” speakers due to all the obstructions.

Does anyone know how much mounting room we have for the 4” mid? The Match 4” fronts are 1-3/8” deep and I’m looking at the Audiofrogs GB40s which are 1-5/8” deep.

Do you know if that extra 1/4” will clear?

I don’t think I’ll take the leap on the Stegs, Etons, or GZ. I can’t get the Rainbows, and not a big fan of Focal tweeters. I’ve looked at a few 3 way sets but finding an upper lever with a tweeter that will fit is a little tough, and if it does, it’s a 3” or 2.5” mid, which is too small. If I blow my cash on the DSP, then I can’t really swing JL C7 components either.

I will say this, Match has all the information you could ever want. They give you detailed specs, measurements, and instructions. All the other plug and play options are missing at least some info (Eton is missing most).

BENZDUDE, the videos are a big help, they’ve taken away a lot of my fear of getting a tune started that won’t blow any of the equipment. I appreciate them.

I didn't measure depth, but I think you should be fine. It wouldn't hurt to remove one back door panel and measure.

Here is a view from the side showing the stock speaker height

Your match speakers look great in there. I’ll do a squish test to get the clearance or pull off the speaker grills, remount the door panel and measure.

Going through all these threads is awesome. Really makes this stuff possible without paying a ton in labor.

benzdude

Speaker grilles don't pull off from outside and are attached to the upper trim piece.

These are after market ambient grilles I installed.


I filled in the space between them with foam to direct all sound outwards, before installing the match speakers.

C63S AMiGo

Question for another thread, but did you do a 64 color ambient upgrade?

benzdude

Nope. I have 3 color factory ambient so i just tapped into the existing wires.

C63S AMiGo

Gotcha. I have yet to find someone who has the 64 upgrade on a coupe

benzdude

64 ambient just means more wires to tap, if you already have factory ambient. I believe its 5 wires.

Audiotec Fischer has now made a well written manual for the ZEN-M and their DSP AMPS. (Are they buying NAV-TV as a company or just a colab?)

I just picked up a '21 C63S and the sound is well below what I had in the '18 Mustang I traded in. The sound is thin and boomy. I was thinking of doing a swap out of the OEM speakers to the Match plug and play speakers. Did you have to use any additional external LPF/HPFs? Would you say the upgrade was worth it even before you put in the amp/dsp?

Thanks

PaulR7

You'll definitely want to upgrade the amplifier and it should probably be the first thing you do in the car to get better sound.
I changed my front doors to the Match speakers before doing the amplifier and whilst the sound was improved a lot (probably more to do with the tweeters which I lacked rather than the 4" drivers) it still lacked a lot, especially in the bass department.
You don't need any more filters, the tweeter ones are included in the box.

benzdude

Most of the Match speakers feature passive crossovers (see pics). The tweeters come little external boxes that allow 0, -3, or -6 attenuation. I left mine all at 0.

You can do your upgrade in stages:

1. First thing I would try is adding a trunk sub and adjusting mid, treble and bass, surround and fade values to your liking. (if statisfied stop here)

​​​​2. You can also replace the front woofers*

*The front woofers do need some DSP adjustments to sound the best.

(if statisfied stop here)

3. If not, replace the front and rear door speakers (if statisfied stop here)
​​​
4. If not, add a DSP amplifier and tune the sound to your liking. You can leave the center and surrounds on the factory amp and balance everything out.

5. Finally, You can replace all speakers, factory amp and tune all 9 channels and never be able to stop tweaking the sound.

I am at stage 5 currently.

if you car is non burmester audio, Match has all of the plug and play cables and amps to make the job easier.

benzdude

I spoke too soon, there is a stage 6.

If you have extra channels on your DSP amp (mine has 12, only 9.used) or an extra Amp, you can run additional speaker wires to the front doors and add some extra mid bass speakers to the front. Overkill?

I have the cabrio/convertible so trunk space is already thin. I may go that route changing the front woofers first and then the other components later. There are some sellers on ebay that sell a Match W205 Speaker upgrade kit which seems to be at a discount. The change out seems fairly straight forward, but AMPs and DSPs gets out of my scope of knowledge, To be honest I want to stay away from it since I have spent enough time and money on home theater as is.

PaulR7

I went with Match M5DSP mk2, front components and rear coaxials and managed to get myself a set of Burmester footwell woofers.
For myself that's mostly a very adequate system but then I'm no audiophile and never sat in a competition car so I lack in terms of experience.
I'm thinking if I got the Match footwell woofers (8" rather than the measly 6.5") I'd be very content with the car.
Also, I just remembered that I added Noico sound deadening mats to all of the doors and most of the boot which also made a massive difference to the sound.
If you contact info@allwoodsaudio.com I think they still do worldwide shipping and do give a discount over their ebay prices, I've used them for all of my gear.

smbsocal

Great info, thanks for the tip. I will reach out to them.

benzdude

I purchased all my Match and ATF stuff from allwoodsaudio.

They are great sellers and respond very quickly to questions.

The problem nowadays is the Ebay logistics shipping is very $$$$ expensive and you get taxed on top.of that.

EBay uses pittney bowes shipper who i would never recommend to my worst enemy.

I had to resort to using a UK address for inexpensive delivery.

I would try the speaker swap first, it's the least expensive/invasive. It made a huge difference in my system coming from the Audio-20 stock junk. Although I did eventually go the full route of DSP/subwoofer, but I'm an audiophile =)

And if you're located in the US, it looks like a prominent audio website (not sure if I can mention by name) now carries the Match front/rear speakers. That will save you a lot of shipping money and weeks of waiting!

Why would you go with 4ohm subs? Focal now makes 2ohm factory replacement subs too.
