Need advice on stereo build....

[mengel]

With a tax return coming I am finally upgrading my 370Z base "crap" sound system. I am putting a list of things I am thinking about getting and I am not an expert and need your HELP. Some of the components I like other things people in audio business said they were good. Please let me know what you think of what I want to get and let me know if I am missing something or a better product. I trust you guys so much more than brick and mortar car stereo guys. I don't care what brand but I dont want to spend crazy $. I want good crisp sound with natural sounding base. I dont need to win a car stereo competition but I want rock to sound like rock and if I play some rap music I want to hear the base. I am 37 and have not had to think about this stuff for about 15 years and time have changed any help would be great.
