What size amp do I need to power 2-12" subs that are 2500 watts rims each

rule of thumb an electrical engineer gave me:

current draw average should generally be 50-55% of the power supply's max output, ie the amp
Max peak draw should never exceed 75-80% of the power supply's max output, - that one sez minimum 6500 watt amp

personally, i like to be real conservative - the more headroom between power draw and output capability on the amp, the longer that amp is going to last, plus there are other factors - at 50% output, the amp's power will be cleaner, ie very little distortion. I'd go with at least a 7500 watt amp

And do consider how you intend to wire the subs and other speakers:

E.g. serial or parallel.

There are other similar links to be found.

Plan it all out carefully and double check the amplifier power requirements.
