Hi (what is your name by the way?) SL03WLY,
I’m glad I didn’t bore you out of your mind!
People give you their opinion with the amount of knowledge that they know. I’m sure the person that gave you this information about car stereo only told you what he knew about it, if that makes sense?
Your Kenwood head unit; I looked at the specs, and It is actually a pretty good head unit, I was quite impressed with the performance figures.
The Phoenix (Great pedigree) gold 8 inch sub box; may I ask you why you picked such a small sub size?
Is it because of usage of the boot in the car?
I always recommend people to go for at least (dependent on boot space) at 12 inch subwoofer.
Failing that, the smallest I would ever go would be a 10 inch sub.
I just installed a 10” ported with a built in amplifier, into my friends car.
It’s a Vauxhall Corsa
Later on, I will take some pictures and send them to you, if you’d like me to?
If you’re worried about the space, I would’ve gone with a sealed (i.e. non-ported) box.
If you have a look at your RMS specifications on your sub box, it says 125 W, RMS and the peak power is 500W.
The peak power story is for another day, and make you ask, why the hell anyone ever goes with peak power?
Here is a link (worth a read) that will explain to you what RMS actually means in terms of stereo performance.
When you’re researching the wattage of musical instrument/pro audio speaker drivers, you will often find two values for the power handling rating: RMS (root mean square), and “peak.” It’s important to know what each of these refers to in order to find the correct speaker for your amplifier. Mean...

To answer your question about RMS and quality, it always starts with the head unit, then it goes to the amplifiers and speakers that you may have.
One of the greatest things that you could ever get for your car stereo is high quality RCA cables.
The quality is dependent on kind of music you listen to and how loud you listen to it, to a point?
May I ask you where are you live in this great country of ours?
