The industry standard is 4 ohm so you'll only draw half the power from the factory setup with most aftermarket speakers. My setup is completely aftermarket, I can show you pics of the removed RF speakers in the morning when I go home.

Curious how you know that they are 2 ohms? Which doors?

Cheers

425 watts, 10 speakers

(1) 8" dual voice-coil subwoofer on rear deck
(1) 2" mid-range on the dash
(2) 6" mid-bass front doors
(2) 1" tweeters front doors
(2) 6" midrange and 1" tweeter passenger doors full range (coaxials)

The front-door midbass drivers and rear-door coaxials get 50 watts each, the front tweeters and center channel get 25 watts and the sub gets 150 watts.

Awesome, that's exactly what I was FIGURING...how did you find those numbers out?

And since all of the other speakers are 2 Ohms - I'm guessing the sub is probably also.
(two 4-Ohm voice coils, wired parallel into 2 Ohms)

I got the numbers from an Edmonds review. I also turned up a picture of the tweeter removed and it was stamped 4 ohms on the back so I wouldn't bank that all the speakers are 2 ohms since at least the front tweeters are not. Replacement speakers from Crutchfield are 4 ohms for the door speakers both front and back. The subwoofer is 2 ohm, 1 ohm in each coil.

The RF system was standard on the US SLS model and an option for the Sport trim. On the SLS there was an optional nav system head unit for 2012 and 2013. (I think). I have PDFs of the original dealer marketing brouchures which are fun to look at.

I removed the front door speakers to use that install location. I never removed the other speakers, I just don't use them.
I also would bet that the total system wattage is "peak power," not RMS. Probably half, 200ish, and the fact that you can't turn it to max without distortion means less usable power still.

I believe all Kizashi Sport models had the RF system as they were the upper trim levels of the GTS and SLS. They changed packaging slightly over the years but I believe to get the factory nav, you needed the SLS.

No, the Rockford Fosgate system without the nav was 425 Watts RMS.

Reputable companies like Rockford Fosgate rate their amplifiers at RMS and a reasonable amount of distortion like 1% or below. Scammer companies quote their output power at peak with distortion rates of 10% or so, which is unlistenable and dangerous to speakers. Home stereo has very specific laws about how output power may be quoted like: RMS per channel, 20 to 20K Hz, all channels driven, .1% total harmonic distortion. Car stereo is the Wild West in this regard with lots of unscrupulous actors. An amplifier which would be 200 watts in home stereo could easily be advertised at 2,000 watts in the car stereo business.

The quality of this system is not equivalent with RF aftermarket products though. Not their good ones anyway. Better than many stock speakers? Sure. Better than almost any aftermarket items not on the bargain shelf? No.
