Re: What rms rated and peak power rated 6X9's can I use on my MTX Blue Thunder Pro 40
That's a nice old school amp. Back in the 90s when that was made 25 watts per channel was plenty. You can run whatever 6x9s you want on this amp. It's not going to be enough power to match speaker RMS power handling numbers, but you might be surprised.
Where do you plan to put 2 pairs of 6x9s and a pair of 3.5" coaxials? If you can't fit 6x9s up front I would do 1 pair of 6x9s and the 3.5" Polks on the front channels of the amp.
