My friend has a really nice 2000 Integra GS in stick( Its not a GSR but its plenty fast and fun to drive). We were driving to a police station to pay for his ticket

and we started discussing upgrading his car. Now this is nothing new, we talk about this kinda stuff all the time so I wanted to ask what you guys think.
He wants to get a system but he also wants to drop a supercharger in the car.
I told him to get some EDK's

and am trying to convince him to go with 2 12's
.....anyways.........We were arguing what he should do first:
A: Work for a couple of months and buy everythind we need for his Sound System
B: Save up for a much longer time and get a supercharger and worry about the system later.
Neither of us were really sure about what to do first. I love Car Audio but a Supercharger is a Supercharger. That also means months upon months listening to stock speakers
I guess the smart thing to do is save up quickly for a system since it wont take him long and then worry about the engine upgrade but..............
What do you guys think?
