Just trying to figure out a few things before taking the final step.. So far, I have a sub and box that fits in my car, new front components and a cheap amp that I had left over from my previous car. Now what I need is some way to get the signal from my stock NON-BOSE HU, to the amp. From what I've read here, I need an LOC that will convert the differential balanced signals to standard single-ended inputs. I was discussing this with my friend, and he recomended the MTX RE-Q, because he said it fixes the problem of the stock HU turning down your bass at higher volumes. However, I'm unsure if it will convert differential balanced to single-ended. I could go with an LOC that I know does this, but will this other LOC prevent the bass from being choked by the stock HU? I just don't know... The only thing I know that will do what I want, is the JL Cleansweep, but my system is very low-end, and basic, and I don't want to go with such an expensive solution, because it's overkill for my needs. Any ideas, pointers? Really confused here.
