electrical prob

i just intaled a new set of aftermarket headlights on my 2000 honda accord. everytime i drive my car now it seems to lose power to my radio and other accessories such as my alarm system. sometimes i have no power at all when i try to start my car. what could be the problem.....i checked everything i could possibly think of......grounds and all connections seem to be good.

if your trying to start the car and there is no power, check the battery and alternator.
