Helping out a friend. He currently has an alpine 9887 headunit and wants to run active. I suggested for him to get a sundown 50.4, sea neo tweeters and the mli-65 mids. He also wants to run coaxials off his headunit for the rear. Would that cause any problems other then throwing off the sound stage?

I don't believe you can use the preouts along with the internal amplifier..

Depending on what vehicle he has, running coaxials on 1/5 the power in the rear won't do anything because you can't hear them unless you fade to the rear quite a bit, which blows the reasoning for putting such good speakers up front. It was easier in my car where the back speakers were on the rear deck, but in my Explorer with the back speakers facing the middle in the back door.....much harder to hear.
