what is the best loudspeaker avalible for car and audio.

Well, HighWay, there is no "best" speaker. It all depends on what your preferences are.

I suspect that you are a "boomer" -- you like bass, lots of it, with plenty of impact. (Now why would I think that, of someone driving a modified Honda at speeds approaching double the speed limit?) The speakers you like playing Crystal Method would make me crazy playing Mozart flute concertos.

There is a lot more to speaker evaluation than specifications -- those specifications don't take into account less measurable qualities such as warmth, mellowness, smoothness, and different speakers will have differences in these attributes.

For example, my "stereo guy" (owns the shop that I patronize) has told me that even though MB Quart is a highly respected name in car audio, I won't like their subwoofers because they are too "heavy" sounding. You, on the other hand, might find them exactly what you are looking for.

Whether one speaker is "better" than another depends on application requirements and listener preference.
