Question
i have a 10" rockford fosgate dual 4-ohm p3d410 rms 400 peak 800. What is the recommended amp for this sub and/or recommended amp to get the full potential out of this sub? thanks
Wattage spec is meaningless; you can ignore that. Sensitivity is more important for design and setup.
Any good amp that will drive a 2 ohm load is best. Put the two voice coils in parallel - which give a 2 ohm load - and use an amp that is bridgeable for 2 ohm loads. And, away you go.
Let me know if you need more.

PS: Sensitivity is 83 db which is pretty low. So, you need at least 100w of good power. But, 400 watts would really make it rock.
