well wire diagram said red wire is power and black is ground...

there are only three different colored wires..

1.red
2.black
3.yellow(kinda figured this would be connect to an acc power wire)

i know i didnt wired it wrong..

keep in mind that they did work when i first installed them..just not now..

should i take it to an electrical specialist to hear their opinion first, or should i just send em back
