What? Uhh dude just because your speakers can handle up to 300w each don't mean this little amp can put out 600w lol. What is your logic on this. With a power supply of 32volt 5A it will supply up to 160watts of RMS. There is a power supply upgrade up to 48v 5A and do the math that's 240watts of RMS. It might can do bursts of more power but only so little more before you kill the amp. Speakers can still sound really good off 50w each RMS that's what you're hearing Just don't expect to hit your speakers max power handling. With the stock power supply my BT20 pro can do about 70~80w per channel on 4ohm speakers so 140-160w. I settled for speakers they can do 50w RMS per speaker and burst 100w just so I keep myself from blowing the little amp and they get pretty loud for a medium sized room. I seen it do bursts of 160 to 180w per channel with the upgraded power supply but I wouldn't keep running it like that anyway. A nice 120w per channel bump is already nice.
It is a nice amplifier but even with the 48v power supply it doesn't get anywhere near 300 watts a channel but it is plenty of power anyway to drive even full size speakers. Just because speakers are rated for 300 watts doesn't mean that is what you need.
