My I would like to get more bass out of my system. My sub has a High level in (that says from amp) and a high level out that says (to speakers) Can i use the high level out and hook them up to my mains with the mains already connected to their designated L/R channels. or is the high level in/out stricly for recievers without an LFE output. So the question is, will the high level out output the LFE track to my mains. and is there any possible damage that could be done to the sub, reciever, or mains. Also, if this is possible, will it distort my midrange sounds having all this extra bass coming from the mains? They are only 2way. 10" woofer and tweeter.
