Will installing subwoofers void my warranty?

Hi,

I recently put a down payment on a Tucson 2023 PHEV, so I have lots of time to find out this information lol

I have an nice set of subwoofers from my previous vehicle that I would love to install on my new PHEV when I get it, but I've been cautioned that this may void all or part of the warranty, Does anyone here know if that is true?

Also, any suggestions on cool accessories or customizations that I could do? The new Tucson looks great but I want to add some personal flair to it. I've never had a new vehicle before so I'm excited to see how I can make it look even cooler.

For reference- I "ordered" the Ultimate trim in deep sea blue with a grey interior, however I've been told that I have an opportunity to change that on the real order day and I am thinking to change it to Titan Grey with the black interior.

Thanks!

The Deep Sea Blue is a great color, almost black in somel light, a dark blue in other light. The black is more of a dark dark charcoal. I have seen the light interior after some use and it does seem to get more dirty and noticable than they black. Just my 2 cents though.

Appreciate your opinion, showing dirt and stains is my main concern with the grey interior.

Thanks for the reply!

It wouldn’t be easy to install due to the Bose processor amp. You could try and tap into the speaker leads that go into the amp to get your high level inputs. The standard hybrid has a limit of 350 watts max but since the PHEV has a real 12 volt battery, you should be fine. It wouldn’t void your warranty if it is installed properly.

Great to know, I'll definitely get it professionally installed so hopefully the difficulty doesn't lead to a huge increase in cost.

Thanks for the reply!
I did my subwoofers myself in my hybrid. I used a line out converter on the door speaker wires in the B pillar for signal and got 12v power from the 12v lead under the hood. It's not that bad of a process.

Looks good, clean install!

Did you check with your dealership or anything if that would affect the warranty? My buddy is a mechanic and usually does my installs but this is my first new car and I'm not really sure how warranties work
Found this in the owners manual View attachment 855
That's unfortunate, thanks for the information
I think that you would find that indication in any owner’s manual.

It's actually at the dealership getting a new transmission right now under warranty. They didn't mention the subwoofers at all so I assume they don't care.

the box isn't as big as it looks. It's maybe a foot deep. I put the groceries in the pocket dimension next to the Flux capacitor.

In the PHEV, the 12V battery is located in the trunk where the spare tire usually is, so I guess the install will be even simpler ?

One thing to note, the 12V battery in the PHEV is enclosed into a sealed plastic case to trap vapors case since its inside the cabin.
12V lead acid batteries can produce hydrogen sulfide (H2S) vapors if venting due to overcharging.

When the 12V battery is under the hood, the vapors are not an issue because its kinda a vented area.

Doesn't matter what the manual says. Adding aftermarket accessories is covered on the Magnusson-Moss warranty act.

According to the Magnuson-Moss Warranty Act: a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause of or contributed to the failure of the vehicle (15 U.S.C. 2302 (C)). This means that a vehicle's warranty cannot be "voided;" the dealer can only deny a claim if the stock part failed due to damage or unreasonable use.

you've obviously never had a subwoofer, enjoying bass with your music doesn't have to annoy anyone. Thanks for the pointless comment lol

I'm actually on my 4th Tucson this year. The first three burned down from blasting music in my neighborhoods driveway at 3am. Just don't tell my insurance.
Yep, if it causes a failure of another part or sets the Hybrid electrical system on fire.

Read the warrenty manual, its lengthy and quite the process to even make a claim starting with the BBB Auto line.

The Magnuson-Moss Warranty Act has nothing to due with your case.

Your not installing a aftermarket part to replace a OEM part that meets or exceeds a genuine Hyundai part or approved by Hyundai.
