Kia Niro w/Harmon Kardon - Stock speaker replacement

[FamiliarRaspberry805]

Hi All - I am looking to replace the cheap paper cone speakers in my Kia Niro. 8 total speakers but planning to leave the sub, so 7 speakers total. The head unit is factory 320 watts. Anyone have any recommendations on how to choose/pair speakers to this head unit?

Go to crutchfield.com and enter your car model. Common beginner mistake is to replace midrange drivers with coaxials. Check it out, come back and will help you validate what you picked.

Yeah I've been reviewing Crutchfield options all morning. Seems like the fronts can accomodate a 6.5 in the door + 1/2" to 3/4" tweeters on the dash, and the rears would take 6.5" coaxial since there is no separate enclosure for a tweeter. Just to make sure I understand, you're saying go with components in front and then coaxial would be fine for the rear doors?

If they are fullrange, yes but my suggestion would be to leave them stock and save the money for a better set of front components.

OK, here is the list I've got for the fronts. Basically I went with known brands with a max of 90-watts RMS. Not sure how to determine what the max RMS is per channel right now but based on my research it sounds like lower is better for the existing head unit/amp.

Model	Price	Type	RMS
JL c1-650	150​	component	50
Rockford Fosgate r165-S	75​	component	2-40
Infiniti reference REF-6530cx	197​	component	90
Focal ISU165	330​	component	70
JL c1-650se	229​	component	50

Thoughts?

I'd look for something with high sensibility (dB) before rms ratings since you're on factory power. You also don't need to buy a complete component set with crossovers. Just make sure to match the impedance of your stock speakers.

OK I checked sensitivity and these are all 91-93 which seems to be the higher end and I'd assume fairly comparable. Any favorites from the list?

The Focals obviously. Also consider sound proofing your doors. That will truly make a difference.
