No need for the CS if u decide.
A sub should not be powered off a 4 channel that is not designed for it like in your example. Yes, it will work, but no, it will not sound good. Besides, what about the rear speakers? Now your left with a half amplified system, which is a waste.
If you read the posts, you would have also seen that for starters, OP is not adding a system, he is trying to get betted sound from the stock setup with changing it. Which makes your suggestion completely irrelevant.
To finish it off, even if the suggestion you gave was a good one, you would still have use for the CS in order to get the best signal to that amp from the stock head unit. The amplifier may accept high level inputs and advertises that it has a hi/lo converted (or line level converter) built in, but it does not have signal summing or the sound processing that is achieved with the CS or other products like the LC6i/7i.
I think you have completely missed the point of this thread. Not to be a jerk, but it gets on my nerves when people say things that are completely unrelated to the OPs question which only confuses them more, and to top of off, its not even good advise either. Please read first before posting.
