I am in the process of designing my next system and have a few questions. I want to run an all active 3-way setup up front. I haven't decided what speakers I want to go with. My plan for now is to run an Alpine nav head unit, a 4 channel amp for the mids and tweeters and a 2 channel for the midbass. I want the mids/tweeters in custom kick panels and a 8" in the doors for midbass. I also have an AudioControl dm-810. My question is how to properly get the signal from the head unit to the amps and then speakers. I will be running a component set for the mids and highs. The deck I will be getting has 3 preamp outputs. Would I use all three for this setup even though all the speakers will be up front or would I use the front preamp and use y adapters to get the signals to the 2 amps? Also would it matter if the interconnects from the head unit are going to the the "rear" input on the 4 channel even though the speakers will all be up front. One last thing would I still use passive crossover with the comps since I will be using the dm-810 an run an active setup.
