how did you come up with the components you listed? do you have a preference for them for any specific reason(had/heard them in the past, like the brand, etc)?
you links are all to crutchfield, do you plan to order through crutchfield?
i understand the desire for the factory fit/finish on the radio, have you considered some of the 200mm aftermarket radio's that are on the market, and crossed them off the list for some reason?
your goal is to keep to a $400 budget for the audio portion of the build?
are you installing yourself, or are you factoring in having a shop do the work?
what do you hope to achieve/fix with installing all this new gear?
what do you listen to?
i think that's enough questions for now
i definitely love playing with the audio on a budget though!
