I’ve been ruminating over a setup I’m putting together. Finally, I’ve found an amp that seems about perfect. Its a DLS classic CA31…it has three channels total, 2×65 RMS at 4ohms typical and 1×280 (mono) at 2ohms typical. I know for sure the sub I’m going to be running is rated at 300 watts RMS…I haven’t decided for sure on components, but the ones I’m looking at are either a bit under the rating (50 watts rms), a bit over (80 watts rms), or a lot over (150 watts RMS).
So, how close does the RMS rating of the speaker need to be to the RMS rating of the amplifier?
My main question is going under…IE: the speakers I’m really siding with are 80 RMS, whereas the amp is 65 RMS….the sub I have is 300 RMS, whereas the amp is 280 RMS…
The rms rating of the speaker can go over the amount of the amp by any number as long as the speakers getting the minimum amount of power required to operate and it will not be damaged BUT I wouldnt take the power of the amp above the rms of the speaker by more than 75% without expecting to shorten the life of the speaker.
The rms means that the device (amp or speaker) will put out or take that amount of power all day with no ill effects, the max on the other hand or anything respectivly close to it is only what the device will do for a short period of time before it fails
In all honesty going over a little isn’t going to hurt them any… but obviously going over a lot will damage them…. its all common sence… just be careful
Good Luck

I would try to match them as close as possible but with the numbers youve provided i think you will be fine with any choice
kk the closer the better. however its better to be over the rms than under it. so heres an example. u have a 200 watt rms, 300 peak watt sub. ur best bet is to run it at 250 watts, that way u have ur not under or overpowering it. its perfect.
