I have a Bose Lifestyle 18 and a Bose Cinemate 123. The Lifestyle system has a receiver built in, which I really want, but the bass is just not quite where I want it to be, even adjusting to maximum bass. The Cinemate has amazing bass but no receiver. I've recently removed the Cinemate and installed the Lifestyle but there's just not enough bass so I'd like to know how I can connect both systems together to my TV/DVD/cable so I can use both bass boxes and all 7 satellite speakers.
