[dodo]

hi, i'm new and i don't know much, so here's the question:
can i connect these 2 speakers:

Sinustec 13909 St 100 (10 cm) 2-Way System , Black : Amazon.co.uk: Electronics & Photo

Sinustec 13909 St 100 (10 cm) 2-Way System , Black : Amazon.co.uk: Electronics & Photo

to my car stereo which has 4x50W output.
will it have enough power to supply these speakers, or do i need amp for it?

sorry if it seems stupid question.

head unit is 4 channel, 50W for each channel (RMS)
does that mean it has 200W output in total?

speakers are 4 ohm, RMS output power 100W
does that mean my head unit has just enough power to run these 2 speakers?

hep me dammit im confused.
can't find any newbie friendly info about this on YT.
