I am installing a new kenwood deck in my 2004 kia optima and by passing the factory amp. I am getting no radio reception but the cd sounds great.I checked my antena conection and it is snug. I herd there could be a reception booster that I may have by passed when I by passed the amp. has anyone ever come across that problem. does anyone know what I can do.

Yea, sounds like the Kia uses an amplified antenna. You'll need to get hold of the factory wiring diagram.

Support the12volt.comThis might actually be a simple fix. Try this ... did you get a wiring adaptor? Did you cut the Kia radio plug off of the Kia harness? I hope not. If you did not cut the Kia plug off, go get a wiring adaptor for the car if you haven't already got one. The adaptor should have a blue wire in it ... possibly a blue-with-white-stripe wire as well. Hook these blue wires to the new radio's blue wire.
If you have cut the Kia plug off, I agree with DYohn - you'll need access to the factory color codes. Find the wire that is used to turn on the Kia amp and/or the wire that turns on the antenna. According to some technical info that I have, the factory amp trigger is green and the factory power antenna trigger is grey. Hook these Kia wires to the new radio's blue wire.
Making these connections - even though you have by-passed the Kia amp - may turn on any amplified antenna that is in the car.
Hope this helped ya, man!
Good Luck!
