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 -_-.

I personally ended up going with 8" subs in the doors because I wanted good bass without sacrificing the vert's already small trunk. I assume you are no longer going that route; especially because you already have selected quite a beefy sub. However, if you are not an absolute bass fanatic and don't mind dynamating your doors, you can get two JL Audio 8w0's. They fit your doors with some very minor dremeling for the magnet. JL Audio always underrates their speakers; I've got a pair of 8w0's running at 130w rms apiece and have had no problems so far. As long as you are not an aggressive user and have clean power (don't overdrive the amp), going half-again as much power with JL's is not a problem.

It's probably not the solution you're looking for, but figured I'd let you know. 8w0's are about $90 apiece, and are only sold by dealers, so you can't get them off the internet.
