Hi everyone. I want to get a more powerful subwoofer for my Stereo (It came with a 160W Sub). If I get an active 300W Sub, will the bass actually be 300W? My stereo feeds 160W through the Sub channel, but because the new Sub will have a more powerful built-in amp, wont it sound like it? Main reason is because my mother is not impressed with her Home cinemas Sub, so I thought ill give her my old one as its better. Thanks.
