If one has good "feeding" available, then low Qts might not be an issue at all. For general usage Qt of .5 or .6 is a good idea.

Exactly. Even careful adjustment of LP frequency and amplifier level adjustments alone can transform things quite a bit.

TS-W306R | Pioneer

That's why I'm wondering is this ok for my application.
It is OK, do not look further.

The Pioneer speaker has a 4 cm voice coil. This is good for, maybe 100W rms. Not really a sub woofer, seems to be a cheap junk design rip off. 350 W rms look for a, at least, 75mm VC.

The Qts for an "free air" woofer should be around 0.6-0.8 Low resonance frequency around 30 Hz is fine, too. So look for 12" woofer or larger with these parameters.
"free air" is what you call a in car installation which is close to infinite baffle, where the volume of a box can not be calculated, because it is more or less open= very high losses. The virtual volume of that cavity may even change with frequency.

A woofer with a Qts lower than 0,7 may need some boost, which explains the need for high power in car installations.
A lot of cheaper PA speakers will work inside a car, as long as you keep it dry.
I even had dedicated car speakers rusting away, so all day, all year use off a car HIFI installation may need some attention.

A funny thing about large cone diameter /displacement in a car with closed doors/ windows, is the point where the car becomes a pressure chamber. Car HIFI is so far away from "normal" Hifi, some even think it is no Hifi. Which in many cases may be right. Like these Pioneer woofers...

If you do not want to measure your results with a microphone, a good indicator you make some serious bass is when the number plates start making noise and you have to glue them down.

We don't know what the rest of the system is, so it's a guessing game as to what the OP needs to integrate well. But with a claimed 96dB sensitivity, if the Pioneers can deal with anywhere close to 100W RMS, they'll be more than enough if the goal is listening to music.

If he just want to rattle his tag or annoy people as he drives by, then ya'll go ahead and knock yourselves out.
