OK, so I've never dealt with LOC's, I've always used aftermarket decks. But since very soon I'll be adding an RB1, I'm going to need these. My question is, when I tie a line into say the rear right channel, does that line need to be dedicated to the LOC or can it still power that right rear 6x9 and send the signal to my LOC at the same time. I wanna throw some subs into my trunk before I build the rest of my system just to get some thump for now. Don't have the money to do the whole thing at once.
