If you use a factory radio alot of times the radio stops raising the bass level at half way and line drivers are used to keep a more accurate an consistant voltage

Which means? Let say you do not have any choice since you have an integrated HU, but to run high speaker inputs. What's the best thing to do to avoid distortions?

Audio Control LC2i

Two Channel Line Out Converter with AccuBASS™ and Subwoofer Control - LC2i

I bought this because I have my stock Bose Navigational unit. You connect it as you would an LOC, either by tapping into your rear factory speaker wires, or by tapping into the speaker wires from the HU, right before the amp in the back. It has 2 preouts, one for full range, and one for subs. It has an automatic sensor on the unit so you dont have to run a remote wire to it. At same time, it does have remote outs on the unit to run to your amps. Therefore, that eliminates trying to find a remote wire somewhere in your car to run your system. Most factory radios stop getting louder at a certain point when aftermarket equipment is added. This unit supposedly bypasses that issue. I havent hooked this up in my car yet, but I don't anticipate any problems at all once I do. Watch the video in the link and they will go into more detail on how it works.

Also, I got mine from crutchfield and it was listed for $99. I used a coupon for $20 off for all orders over $100. I just bought a little 6" piece of speaker wire to get my cart over $100. Hope this helps.

if it already has hi-level inputs, you should just use that instead of a separate loc. i would find out a bit about your factory head unit first though. if its one of those 'premium' units, many of them have built-in eq's, usually at the amp, tailored to their speakers for that car. using that altered signal with aftermarket speakers and subs may not sound good. with these systems, its better to get a differential converter and install it before the factory amp. this allows it to get a flat (assuming) signal before it gets eq'd.
