Thanks, great idea to take signals there, in my previous Giulia it was a paint in ass to pull them from central infotainment unit back to amplifier, because door sill plastics were impossible to dissmantle without damage. If its not too late, since it is pre-corona post, when tapping signals from the B-pillar, you pulled signal wires inside the cabin without dissmantling door sills and B-pillar bottoms?

 

I'm attempting this same install on a 2022 Stelvio. It's been a bit since this post, but just in case: I'm totally stuck on how to run the wires from the tap-in point at the door pillar to the trunk. They seem to run inside the body somehow, but I've been poking around and removing panels for a few hours and I can't find the path. Any help would be greatly appreciated!

 

Hi all!
now, how about those of us that have a spare? Where to for the sub?

 

What is the point to all that?

 

This is so American haha!

 

I added to my stelvio using the same spot to get connection for the RCA converter two amps, two 12” subwoofers, 2 3.5” tweeters and 4 6.5” mid speakers and my car is really loud

 

Could you please post a link for the DSP?
I can't find an Alfa specific 1 on EBay here in the U.S.
Not having to cut wires would be perfect for me.
Thanks

 

Hi, sorry I'm not sure the question is for me, but if it is, here's the link to such DSP from amazon.com

Never heard of that brand, looks like a solid unit though the processing specs and install flexibility is great! The price on eBay is pretty awesome all considered, probably a great buy.

 

I forgot to mention that another reason why I have chosen that dsp, is because it comes with an harness that perfectly fitted my Stelvio. When you order the dsp, you specify the make and model of your car, and they send you the right cables. This was important for me to not cut any original car wirings.

 

Hi there.

In my case I had two goals: spend as low as possible, but with at least a decent sound quality, and be able to bring easily the car back to standard, since it's long term rent car (4 years). So I went for the following:

DSP: Puzu pz-c7 amplifier + dsp, a decent chinese 4-ch + sub dsp. I had an alternative in mind, which was the pioneer DEQ S1000A DSP.

The reason for choosing the puzu dsp were:

#1: it's size. It's so small that I have been able to attach it directly to the ETM with some velcro tape. Other DSPs are larger and force you to place it in the trunk, so you'll need to drive quite a large number of cables back/forth from/to the dsp and the ETM, making the installatio much more complicated.

#2: Price

#3: It is capable of receving both low level and high level inputs, so much flexibility. It also has RCA sub outputs and a 15 bands parametric EQ with quite a number of useful settings.

#4: I can fully configure and control it also with my android phone, via a BT connection.

#5: It incorporates an amplifier, so it's not a pure dsp, but an amplifier+dsp

So I wanted to give it a try and picked this one.

As far as the sub is concerned, I went off for the Kenwood KSC-SW11. It is a 150W max active (amplified) sub that I fitted in the same space like many others here on the forum, that is underneath the floor in the trunk.

In case you'r curious to know more about how it's going, the overall performances, etc, I can post here a link to the Italian Stelvio forum, where I opened a (quite long already!) thread on this installation, with plenty of pictures about the install. Over the next days, now that the installation is complete, I'll go on with the measurement of the performance, and the tuning, using proper tech equipements (that is: calibrated microphone, a "serious" sound card, the REW audio software, a USB digital mixer and a few other things.

I know it's in Italian, but Google translate can help - at least I do so, when I visit forum that speak languages other than Italian and English

Funny enough, I took so many ideas, inspiration and help right from THIS forum, before I decided to go on and embark into my own mods!

 

If it makes you feel better, the upgraded system isn't much better.....alot of us wish we'de saved that money. It's clean and tonally nice but lacks impact.

But yes @agatti, what dsp and sub did you get?

 

I hope it is visible in this post: you see that 3.5" midranges have been added. I don't know how to remove the plastic panels that cover the place where the speakers have been added. I think someone called these pieces/places "D pillars".

Adding powered sub to base system:)

Hey guys/gals,new here. I recently purchased a 2018 Stelvio Ti sport and was wanting to add a powered sub to enhance the base stereo system. I joined this forum hoping that I could find where someone has already gone through the process & as well had best place to tap/wire color details...

www.stelvioforum.com

 

How did you run the wires inside the vehicle back to the sub once you tapped into the L/R rear speaker leads?

 

Hi, congrats for your upgraded system. I know this is an old thread, however I wanted to ask if you could share how you removed the rear panel that hides the place where you install the additional 3.5" speakers. I see you took a pic of where they should be placed.

Thanks!
Ag

 

I have the base system, and when I was working on mine, there wasn't a spot for the extra 3.5". I'm guessing that is in the HK set up. Bummed me out when I was looking for it.

 

I'm slowly but surely getting the base system upgraded. Running all CV set up. Replacing all door speakers, and going to have them run off of 4 channel amp, as also running a 10" amplified sub.

 

Reviving an old thread as i want to perform this upgrade myself.
It's been years since i worked on ICE but this seems very straight forward tho there are no pictures of how to remove the panels or get to the wires.

@Scottlarson737

Where did you pull the sub wire from? From the sub itself?
Where did you connect the ground and where did you get the power from?

I really don't want any shortcuts or fires

 

do any of the sub additions mentioned here cause a code to appear on the screen? thanks!

 

When you tap both side on the rear speaker how do you pass the cable to the inside I been trying but I can’t

 

When Best Buy did my install, the tech said he tapped both sides.

 

Hello there Scott Larson. I reached out to Crutchfield, and had spoken with a couple of their techs. They had no experience with the Stelvio, but said what you suggested, which is they know that with such an installation, it is about wiring. I was not that comfortable with doing this, though I had done head units and speakers etc. Just not on my newer Stelvio, which we know can have its own issues to begin with. I even spoke with their lead Customer Service guy, who was nice, but he had no knowledge but he would put me to the techs. Problem is that even with me sending the videos from the Forum, he put me on the backburner through the holidays, and that made me feel unloved. Why should I have to wait, while they helped, presumably, other customers. Best Buy ran a sale and had open box excellent condition, so worth a shot. Item arrived in a day, and install scheduled, with a guy who felt quite comfortable doing it. All worked out. Hope you are staying warm, and if ever down here, still will get that beer to you. Mark

 

Great to hear, Mark! Sorry to hear about Crutchfield . . . Def not my experience. They knew wire colors, where they were, etc. Always nice to have someone else do the work. Being that you got such a good deal on the speaker, it only made sense to spend the extra on the install. Welcome to a proper system!

-Scott

 

Well, my Kicker Sub has been installed by local Best Buy in Altamonte Springs. OMG, not only did my installer David Ramos do an amazing job, clean, no wiring showing anywhere, it sounds much better, filling out the missing lows. Nothing like Beastie Boys Licensed to Ill, like college days, in the Stelvio. Cost me 180 for an open box, excellent condition Kicker, retailing for $300, and $128 with tax for install. Crutchfield, I have purchased from the in past. They have no knowledge of the Stelvio, and even with me providing them info about folks on this forum doing the installs, they are disinterested, and I have no use for them anymore. Good times, Mark

 

Can you please tell me which specific kicker sub you got? I may copy what you did here and just take it into best buy for the install. I have a 2019 base stereo no sub in the back and I want to try this first before paying 1000+ for a custom fiberglass sub in the back and or an entire system.

 

So i bought a kicker hideaway compact powered sub. Best Buy had a great open box deal, too good to pass up. So, if you will, some questions please. First, anyone have any issues with it under the back cover near the battery after time with theirs in there? Heat, vibration, poor sound? Second, please, what wiring kit is best for this application. Even if I have someone install it, which kit to buy? 10 awg, 4 or which brand? So many online to choose from. Is there a need for the LOC? Some, if i recall, did not use this? Do I need it? Thank you and much appreciated. Mark

 

Wanted to quickly mention that the stereo sounds much (much) better using Amazon Music on HD-only (Highest fidelity) setting, via car play. Superior to Tidal in my opinion, which was somewhat surprising.

I am now wondering whether my FM antenna is defective or perhaps not properly installed. The FM-Hd radio reception and quality so so bad, I assumed the stereo just wasn’t good. Now that I know it is capable of solid sound, my suspicion has turned to the FM tuner and antenna.

anyone else experience anything like this?

Maybe i should move this to a new thread.

 

On a slightly related note, I’ve been driving the last few days with my rear seats folded and noticed the stock sub seems to hit way harder than with the seats up. Probably the cheapest mod for this!

 

thanks spdklz. i am spending on H&R springs, forza exhaust controller and ceramic Pro treatment first, but getting this done is 4th on my list. I am in DFW often so this could be a good option. So why would you need a controller for the sub?
