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. Unfortunately I found nothing. So I have got the installation complete and thought I’d share my process & hope it will help someone else in need. I first started with tapping the rear door speakers, very easy to hide the wire and keep it clean. Tap each side L- orange/orange-blk stripe twisted together,,,R-green/green blk stripe,, picture includes of where I tapped to keep it clean. Returned first sub, thought it was blown till I got a second and had same problem, sounded blown and would cut out on protect mode. Do yourself a favor and purchase a LOC converter, it worked great after installing this product. It’s almost as the rear styrofoam area was meant for this sub, fit beautiful with a few modifications (drill holes for wires). While I had rear left panel off tapping remote turn on wire to 12v plug I noticed there is a spot for 3.5” speakers, so ran wire for those and have Rockford Fosgate on order. I also hooked up some basic tweeters inside that panel for a bit extra from rear. I may have left something out but hope the pictures or the proper colored wires will help someone in there attempt. Good luck

Thinking of taking a shot at one of these sub-mods. Lots of good info from Fire2K1, Troy810washere, ifly4fun and Scottlarson737.

I'd like to first get some feedback on removing those interior panels without wrecking them. Any experience on that ?


Also, any thoughts on getting the all-in-one sub/amp like Kicker Hideaway vs. bypass the entire factory system with a new amp and sub.

( I have HK upgrade system with existing, factory sub.)


thanks All !

Hey group, If you are in Dallas Texas and want a sub upgrade... I just had TintWorld in The Colony Texas do mine for $1,350. Did some sound deadening and 300watt amp with a Memphis dual coil sub. Sounds great and it if perfectly in the stock enclosure on the HK system. I also did a bass controller run right to the drivers console by my right leg. The manual control isn't necessary but they put it in, I like having it.

Ask for Sean, tell them Matt sent you. PM me for any details.

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.

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

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.

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!

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

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 :D

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".

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!

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.
