\rHi Irving:
Your best choice for the FORZA10 would be our SMP-300 rated at 250 W continuous and 500 Watts peak. And since the FORZA10 is rated at 4 ohm it will draw more power from the SMP-300. Which is good since at 86 dB sensitivity the FORZA10 needs a little more power to fire up. Note in order to add a second FORZA10 you will need to add another SMP 300. You can not connect two 4-ohm FORZA10 Subs (creating 2-ohm load) to any of our SMP Subwoofer Amplifiers. So unfortunately you would have to add a second SMP-300 amp if adding that second FORZA10. Note your Pyle amp has a single right and left output Sub-woofer output. If you added two SMP-300 you would daisy chain them together.
Good Luck
