How much over RMS can you go?

When you look for an amp for your subs, you will need about 15-20% of headroom. Headroom is extra power above the combined RMS. If your subs are 300 watts RMS combined, then you need 345-360 Watts RMS to have safe headroom. If you go above that, then you will overpower your subs, and damage them.

What is a good RMS for subs?

It is recommended that you go with at least 100 watts RMS in order to get a decent amount of power for your subwoofer. This will make sure that your speakers are loud and clear, but it can be improved by using an amplifier as well.

Is 200 watt RMS good?

A 200 watt RMS power rating is how much power a speaker can handle, not how much it requires. Even a 200 watt speaker can sound great with only 30% (60 watts) power applied. However, you'll have low SPL (sound pressure level) or "loudness" with this little power.

Is 80 watts RMS good?

80 watts of power is more than enough for most applications. But the real #'s that count are the sensitivity of your speakers and the powerband of the amp. If you speakers have a sensitivity of 88db they will sound half as loud as speakers with a 91db sensitivity.
