hey guys.. i installed a 1000 watt amp in my car about a week ago. after a couple of days, i'm having some really hard time starting the car up. but the funny thing is when i start it up in the morning, it starts up fine but after a nice slow ride to school and when i got out of class, the car didnt want to start. finally it turned over and i thought it was a one time deal. it happened the next day too and now this morning, it did the same thing but once i got it to start, it couldn't idle right. i revved it to about 3k rpm and let backed off, it was fine. the rest of the day, it started like normal. so im thinking, maybe the battery is dieing on me. i got it checked and the battery was tested as "good" and the voltage turns out to be normal. then i also started to notice a few things wrong when my hazard light inside the car doesnt light up anymore and also the ash tray light is out too!

is there something wrong with the electrial system or is it just having a bad month? ps.. what size bulb could i replace them with or is it just the perfect time for me to go LED.
