Seeing as i have already bought a box for the underfloor i will go with that for now, but changing around boxes is a piece of cake. I also have a 12" directed Subwoofer in a normal standar sized box so can run both, video both and show the sound difference.
I plan to make a video of the sound system cranking before and afterwards so a comparision can be demonstrated.
Your points in your other post are exactly as i have been thinking. Going the OE route looks a very exspensive option to get to the same level of sound system. As things stand at the moment with the components i have bought it's going to cost £1000 + OE would be getting closer to £2000 once i had factored in fitting.
OE head unit with CD's is good and as i understand is made by Alpine, but with MP3's particularyly through the parrot kit i have make me turn the music off. It sounds flat as a pancake. Music i love i can't listen to so i end up listening to the radio or engine.
