Answer
There is no sensor in the car, just bad installers
i need more details, no rca jacks on the factory radio, what did you use ?
where is the power coming from ?
where is the ground coming from?
what about the remote wire ?
what equipment are you using,

you purchase a new amp woofer and they did the installation after you, did you pay them? return their amplifier and woofers ?  Bad installers
tell me more, give all the detail
