Sound System Questions, 5 quick questions :) Options

[JonCars17]

I have a few sound system questions.

I'm thinking of adding a sound system to my car by the end of May which gives me enough time to save up.

Q1:
What is the point in putting a Sub (8") in both side doors?

Q2:
How much should I roughly look at spending for the system (components in the front, 2 speakers in the back, headunit and a sub 10" with an amp)? I'd like to get one for qaulity and not the extreme bass.

Q3:
What should I look at when choosing a system? the Sensivity aka the dB?

Q4:
How do I calculate how much amp I need

Q5:
What can I do to stop the car from rattling once it is installed?


I'm a n00b when dealing with cars -_-.

Thats a pretty decent system. Alpine do make great gear, and the system will be loud, and sound great.

Just want to point out but, its not (mostly always not) going to be the best system, by going all one brand. Gear doesnt "match" up with other audio components of the same brand. It may have extra features, such as Alpine amp control being able to be controlled by some Alpine HU, but theres no audiable advantage with matching brands, unless of course, that particular brand makes the best of those two products.
