there it says the RMS is 400 so i dont know where you got 300 unless this information is incorrect.
here it also says 75-400 RMS, so we know it is 400 RMS
As for the voice coil it just says 4 ohm but is it DVC or SVC, my guess is SVC but who knows
as for it being underpowered I wouldnt exactly say it is because its in the RMS range (75-400) but you can better I would go for at least 300 watts rms.
