This is one of those cheap bluetooth amps and i don't think i can change gains and things i dont think it has itJust to reinforce this: peak power ratings are meaningless. That’s the absolute most they can handle for millionths of a second without blowing.
So, you’ve got a 50wRMS amp for 40w RMS speakers which is fine, just make sure you set the gains to match the speakers.
Just as an FYI incase it might be helpful: Slowly turn the radio up to a point it starts to sound off, then slowly turn it down until it sounds good then turn it down a bit more [(this is to make sure youre not sending the amp a distorted signal) make sure to remember what volume you end up with). Then slowly turn up the amps gains until the speakers start sounding funny then back the gain off until they sound good again and back off a bit more (to be 100% certain you don’t send them too much power no matter what song you listen to).
Make sure to use either a test tone towards the lower end of the speakers frequency range or music with lots of low end that the speakers will play.
That’s the best way to do it by ear, not the best over all as you’ll end up losing some power. But shouldn’t be noticeable and even if it is it’s far better then risking damage to the speakers.
