My HID bulb won't turn on?

I have a 2012 Honda Civic with aftermarket projector lights. I had HID's installed over a year ago, and my drivers side bulb doesn't turn on. For the past 5-6 months, I noticed that when I start my car, sometimes either the drivers side or passengers side bulb doesn't turn on. So I turn my lights off, and then turn them on and they are fine. But today, my drivers side refuses to turn on. It flickers for just about half of a second and thats it. What could be the problem? Could I have already blown the bulb? Any advice would be good. I didn't install these HID's on my own. I had an auto light shop do it for me.

Is my catalytic converter the problem?

I have a Honda civic 91 and its a 4th gen sedan. The problem with it is that the engine cranks but it won't start. I checked the spark plugs and they are all good. Battery has been recently replaced. What i don't get is why it starts up at times and doesn't. Could it be by any chance the catalytic converter that's ruined?

Added (1). I checked it recently, it wants to start but it chokes.

How to upgrade an 2001 Honda Civic EX?

Added (1). What kind of interior and exterior upgrades should I make to make my car look more modern? I don't care about performance since this an economical car, this car has less than 100000 miles, and I expect to use it for at least the next 9 years, btw I'm a college sophomore.

2010 Honda Civic LX Speaker Issues?

I recently replaced my front door speakers in my Honda Civic. Now, the back right speaker in my car has given out. I presume this to be true because a rattling noise is coming from the back right of my car whenever I hit bumps in the road or listen to a song with bass. I'm now faced with, in my mind, two options. I could either get a new set of rear speakers or get a subwoofer for my car inside of a box in my trunk. Would a subwoofer replace the function of back speakers? What would it cost to replace the speakers and add a sub? Any suggestion on the speakers to purchase? Any help is greatly appreciated!
