Amp for Subwoofer

What power is the speaker rated at? I used to have a subwoofer that was
rated at 300 watts RMS, 1200 watts peak. At 8 ohms, that is just under
40 amps RMS at rated power, 150 amps at peak.
** Fraid your math is waaaaay off.
Power = "I squared R" or I = sq.rt P/R
So 6.12Arms or 8.6A peak.
Your amp is rated to supply up to 15 Amps into a bridged mono 8 ohm load.
** No way:
I = sq.rt P/R
110/8 = 13.75 so I = 3.7A rms
