2 Cone subwoofer speaker to amp to PC?? Dont know what to do with these DIY


Hi guys,

Im new to forum and im in need of help.
i must be stupid but i dont know what to do. Ive got 2 subwoofer speaker (from 2 different powered subwoofer). They are in cone and i only have the positive and the negative wire on each of them. The bigger one is (120v - 60hz - 140W) the second one is (120v - 60hz - 120W)  I want to make one big subwoofer in a wooden case. Its gonna be use for my PC and i allready got speaker (

 

) They are RCA connection and the main one have a 3.5mm sub out .     im lost because i dont know where to fin a amp that have RCA connection and something for my sub woofer. And all that must be connect to a PC. I dont know if the amp can go directly into my speaker since they have a SubOut.

I dont know if i was clear you can ask questions!
Thank you!

Mike
