Okay, I dont know who to really ask about this but here I go with the few questions I have.
My car: 2000 GMC Yukon. Good condition.
1. How can I make my car go faster. I want to make my car faster. How can I go about doing this?

2. I want better speakers in the car. Would you happen to know a very good brand of speakers and how many I'll need for the car.

3. And I need a new tap/cd/aux plug radio set. Know of any good ones?

Please let me know asap
