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.
