I also agree that a better sub should be a priority, but bass shakers are a lot of fun. I love mine.
To answer your question, consider your bass shakers as passive subwoofers, which is basically how they function. You'll need an amp to power them, and they'll be connected to the amp with speaker wire. You'll need to send the LFE signal from your receiver to that amp.
So the answer to your question is, it depends whether you intend to keep your bass shaker amp near your receiver and other gear, or in the back of the room closer to the seats. If up front, bury speaker wire and buy binding post wall plates. If in back, use RCA wire and connections.
