17 Kia Soul Speaker Questions

[RaymondStrange]

Hello, I'm having a difficult time understanding some things about car audio. I have a 2017 Kia Soul. I would like to upgrade the tweeters, front, and back door speakers. I cant seem to find the answer I'm looking for online.

How do I know how much power the stock system supports?

Can I install new speakers without running out of power? or do I have to have an amp?

Would I need to upgrade the wiring?

Thank you for any help

- I don't have a sub, and I plan to upgrade the in dash LCD (media display?) if that means anything to the questions above

Figure on the stock radio putting out about 8 to 10 watts RMS (root mean square). RMS power is the average continuous power that the built in amplifier in the radio puts out. what you want to do is match the RMS rating of the speaker to the RMS rating of the amplifier or radio RMS rating. It’s better to have the amplifier or radio put out more power than the speaker needs and a good place to start there is about 125%. This is more important with power hungry speakers like woofers and subwoofers though. Tweeters are where it’s less important mainly because they do not require a lot of power. You also want to match the ohm rating of the tweeter/speaker to what was already there unless you’re upgrading all the speakers in which case you could go from 8 ohm to 4 ohms. Also pay attention the sensitivity ratings. Chances are you won’t be able to find out what is already there. I would however guess that the sensitivity rating is high like in the 92-95 percent range.

The first two Dayton tweeters ND16FA & ND20FA listed in this link are nice factory ratio replacement tweeters that you could wire in place of the factory ones and hot glue them in. These are 6 ohms but I think they will work great. Just make sure you put a cap in-line or reuse the existing one to filter out the lower frequencies so you don’t blow the tweeter.

youd get more out of replacing the deck than the speakers if youre just doing one or the other.
