In a way, yes. the amp does not know the power handling or voice coil size of the speaker, simply "sees" the impedance and has a designed output potential, based on that impedance. heck, amps dont even know how many speakers are connected, again, just the load placed on the chnl(s). We can power 1 or a 100 speakers, as long as the impedance is within the amp safe limit. Power would suck to 100 speaker per chnl, but the amp doesnt care :p Luckily, the gain and volume dials can be used to regulate the amp's output, up to its potential.

If this amp has even half its stated RMS, it should NEVER go into thermal shut down driving a pair of 4 ohm 8" coaxials. Even being class-AB and in death valley, the gains should be pretty conservative. If it is a thermal event, it will take more then just lowering the volume to get the amp back on line. The amps usually need a few minute or more to cool. Not ruling out, id just place heat down on my list.

What gauge wiring was used to power the amp and ground? On an amp that size, especially if it’s not super efficient, hopefully it’s 4ga at the bare minimum. Also, check all the fuses, in-line on the power cable (hopefully a 80-100 amp minimum) and if there are any on the amp. I have seen weak fuses, but they’re not visibly blown.

So you had four tower speakers all worked fine? And you upgraded to two kickers that now don’t work properly. Process of elimination sounds like you didn’t wire something correctly Post some pictures of how you wired it up.
