I have read countless audio upgrade threads for the WK2 with the factory Alpine system. A lot of people are using the LC6i in between the factory Alpine amp and the aftermarket amp. Running components up front. The question I want to know is, what do people think about the JL Audio Cleansweep? I have thought about going this route instead of the LC6i.
As seen here.....

The question I have is does the factory Alpine amp send to the front speakers a full range signal, or will I also need to use the Signal Summoning Unit as well? This unit is added when the factory amp system doesn't send full range signals? I.E. are the factory fronts crossed over or no? This is the addition?
