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 -_-.

A1
Subs in the doors aren't necessary. I would only get them custom built in along with the speakers. They will give your system some extra depth from the front.

A2
This all depends on the brands. I'm not an expert on which brands make the best speakers/subs etc.. but I'd shop around and see what different stores offer, u can always test out their equipment. Usually the more $$$ u spend, the better the product.

A3
Sensitivity is not dB-aka loudness. Sensitivity is the range of frequencies the speakers have a response to. It's the overall system that matters in the end. Your tweeters will cover the higher range, your front speakers mid to hi, ur rear speakers are bassier, and ur sub will cover the bass and the kicks.

A4
When looking at the amp wattage, if u match the max watt output of both the amp and the sub, u cant go wrong. Again, ask the store ppls to give u advice on which amp, as prices do vary quite a bit depending on power output and type of amp.

A5
Dynamat. They're thin sheets that absorb sound, making less sound escape the car and also slightly reducing road noise. I got it myself, it does work, and my boot rattles significantly less
