How manny watts does an amp take to power two 12 inch woofers?

Answer 2

info needed to match subs to an amp

number of subs used

the subs impedance (ohms)

the subs setup (SVC or DVC)

the subs RMS (continuous) wattage- not peak/max

Answer 3

you can guess it a bit from speaker design: does it have rubber surround? does it have excursion over/under 10mm? is the voice coil diameter 2", 3" or 4"?

but we can only quess and miss the right wattage with 50% difference...
