Soundman thank you for your rant LoL. It was highly informative. I never really thought about going with an external crossover but you do have the gears in my head turning. You are right I don't have the upgraded Rockford system and the my friends with the older Evo 8/9 tell me my stock sounds awesome compared to theirs. I have also heard that there is a negligible difference is sound between 2 and 3 way speakers, and the last thing I want to do is complicate wiring. Tell you the truth at this point I have no idea how the hell I'm going to get through the wiring mess. Like i said in my past post I plan on mounting the carputer in the trunk and the Evo X's have the battery in the trunk already so that's one advantage. I was thinking of rewiring all the speakers with some better cable because that last thing I want is alternator wine. I had it in my RSX and it drove me nuts! I will definitely take every piece of advice from you. I hope you don't mind me PMing you later with my final decision on what I will be purchasing.
