I need a lot of help with my new udio system in my car. I have a 95 Honda Civic LX (4 door sedan) and have 3-way Pioneer Premier 6.5in. speakers in the front. I plan to put those in the back, and put Pioneer Premier components in the front and the 3-way's in the back. I have a Pioneer 40x4 face which I'm looking to upgrade in the near future. I'm wondering if I need an amp, and if I do, what kind and how much power? Also, how is the Premier line compared to other name brands and especially compared to the regular Pioneer speakers? Is it worth getting the Premiere's? I will eventually get some subs installed, but first I want to get the factory speakers replaced, and then I'll add subs, etc. Thanks for your help!
