I had wondered if the tweets would fit in the stock location. Maybe I'll go ahead with some components for the front then and then go with a coaxial setup for the rear?
Those Polks are 100w RMS, so i would be underpowering them pretty severly. Should I try to find a lower RMS setup? I was seeing some Pioneer, PPI, MB Quart, RF and JL Audio versions down in the 50w RMS range.
