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 right. A sub only carries one channel. It reproduces a mono sound.

Fronts and rears carry two channels each, i.e. stereo sound. So to run 2 sets of speakers (not sub), i.e. fronts AND rears, you need 2 channels for each set, which means 4 channels for your 2 sets of stereo speakers (A Sub is also a speaker btw.)
