It's not really that simple The power handling also depends on how the speaker performs once inside your specific box.

If the speakers really are decent ones then an amp of between 700W and 1500W will do fine. Also bear in mind that most car amps are massively over rated in terms of wattage, and that doubling power will only give you 3dB more SPL which is not that much of an increase.

well, 3dB + means doubling the volume

But I agree that most amplifiers are overrated.

@richie00boy : What amplifier /s did you take into account ?

NO! +10dB is doubling the volume and it requires 10x the power.

Or, you could say that +3dB is doubling the power.
There are 10 types of people in the world. Those who understand binary, and those who don't.
