Does anyone know what size DC-DC converter the Niro HEV uses?


I want to put a small amplifier in to power a subwoofer, but I want to make 100% certain that it won’t pull too much current with the other electrical demands.

I did a write up in the audio section. No issues with mine but didn't use a converter.

Mine has the base model audio equipment in it so there is not reallly anything that will be the same as yours. I want to put a 10” sub under the driver seat so there will be no impact to cargo capacity.

The amp wiring should be the same. You still need an amp.
Im not sure you can get a 10" under the seat but it might could be accomplished.

There is a ton of room in the spare tire or where that should be you could definitely drop something in there and not compromise cargo capacity.

I’m considering a couple of small amps, and trying to do research to prevent my dealership from trying to say the amp exceeds the electrical systems capabilities. So the power for the amp may not come from the same place.


I’ve already taken measurements and since my drivers seat is manual and not electric, there is a LOT of room under there. With using 3/4” MDF, and taking into account the subwoofer displacement, I can build a custom box of right at 0.38 cubic foot. There are four 10” subwoofers that would work in that small of a box and are shallow enough.

In 2014 I bought a Mitsubishi Mirage and built a custom box for under the passenger seat for a single 8” sub. The box was only 4” deep and was only 0.25 cubic feet. With a solid 200 watts RMS going to that sub from a high quality amp, the sub absolutely pounded.


Will a 10” sub fit? Yes but barely. The primary reason why I want to do it is because to my knowledge it hasn’t been done. But before things start, the specs for the DC-DC converter need to be known.

I found an article that stated a Tesla Model S comes with a 180 amp DC-DC converter while a Nissan Leaf has a 135 amp DC-DC converter.

Without saying it, the article insinuates that the Model S converter is the biggest and the Leaf has the smallest DC-DC converter. Research continues until an answer is found.

Check out the Kenwood Kac-m3001 I even run this on the small electric system of my jetski with no issues. It is made for things like this motorcycles, four wheelers and such.

I’m looking at a couple of different marine/power sports amplifiers primarily due to their small size. But before I purchase a single component to get this going, I need to know the Niro’s electrical system inside and out. The more I know and the better the installation the less likely any dealership could void any part of the warranty.

Gotcha. The Kac-m3001 may be a bit much for my 12" I had to turn it down a good bit so you may could go even smaller. But its a small amp for sure.

Got my new license plates today so while at the dealership I asked a service rep about the DC-DC converter size. He had no clue what I was talking about so he went and got a lead mechanic. The lead mechanic understood my question but did not know the exact rating so he pulled up the specs. Unfortunately, the specs only stated voltage output of 12.4v-15.1v but no specs on the amp rating. My search continues........
