Please help me with my current HT. I am using a Marantz SR8200 to run a 5.2 setup. In the future, I would like to add a 3rd sub. Would I run the 3rd sub the same way I am running signal to my second sub (by using a y connect)?? But, would there be any degradation in signal in the 3rd sub, or in all subs? If so, then this would be noticeable correct? (ie. decreased bass response and output?). If there is only one sub out from my receiver, would the 3 subs overload it? All subs are powered by its own built-in amp. Also, is there any way to boost the sub signal from the receiver if there is a loss in signal? I'm currently using 2 Energy S10.2s. Last question. I'm also planning to add 2 rear surround speakers in the future. My Marantz provides 6.1 channels. If I buy two 8ohm speakers for the rear and wire them in series, then bridge them to the last channel of the receiver, would I be getting 6.2 surround with my current HT setup??? I ask this knowing that each rear surround will not get the same amount of watts as my other speakers, hence, not a true 6.1 surround sound experience. I know I have many questions but can anyone please help?! I'm not really interested at this time in purchasing a separate amp for my rears. Thanks for any input.
