\rHi Ricky:
Check out the SMP500 a dedicated Subwoofer Digital Power Amplifier rated a4 400 Watts RMS at 4 ohms. The IWS10 is in-wall subwoofer rated 25 to 200 watts. It is an 8-ohm driver. So wiring 2 in parallel off the same amp will draw your most power at 4-ohm. Notice the IWS10 has a rated sensitivity of 86 dB which means they are less efficient. You are better off having plenty of power rather than just enough. It is the newest member of our SMP amplifiers. We are adding an SMP1000, but that would be too much power for this application.
Good luck
