If you are worrying about your electrical system, these are the steps you need to perform based on how much you want to spend and how much power you will be running.
1) Big 3 upgrade. This consists of upgrading your main 3 charging wires with 1/0 gauge wire vs the stock 8ish gauge. These wires are the Alternator + to battery +, battery - to engine block, and battery - to chassis. These three wires alone will greatly improve the efficiency of your charging system (alternator) and allow you to run more power without seeing your lights dim.
2) Upgrading your stock battery to a better battery. This could be an Optima Red or Yellow top, Kinetik 1800 (or whatever will fit in your car), XS Power D3400, etc.
3) Adding additional batteries.
4) Buying an High Output Alternator
Materials for Big 3 will probably cost around $50, Batteries can be anywhere from $100 to $400ish (my XS Power D3100's were $425 each and that was getting it directly from my XS Power Rep, not buying it at a store), and Alternators can run anywhere from $300 or so up into the $600 range depending on what company and how much amperage you want it to put out.
My suggestions:
Buy a deck. Let me know how much you want to spend and I can recommend you a good one. Probably about 99% probability I will refer you to a Pioneer deck, I'm a little biased. Currently running a Pioneer AVH 4200 DVD that I got for around $500 installed from a friend of mine that works at a shop, locally the deck itself sells for $750 but I'm sure you can find it online for around what I paid.
Next, upgrade all of your speakers. They don't have to be exceptional speakers, but ANYTHING will be better than the stock speakers (even a Bose system will be put to shame). I honestly think the best way to choose speakers is to go to a shop near you and listen to their sound board that way you can compare the speakers to each other on the spot. You will have no idea what a speaker will sound like if you buy blindly online.
Last but not least, add a sub and sub amp. Something small like a single 10" or 12" sub in a ported box off an amp that matches the RMS will hold you over until you get the itch to go louder.
Give me a budget to work with and I can try to build you a system.
