someone told me i should get a signal booster since i have 4 times and am planning on getting more.. the said it was very cheap and definitly couldnt hurt.. another person said i dont need one the way my stuff is set up, and that they are expensive. im not 100% happy with the quality of my headrests tvs, and i feel maybe they just dont have the power in the signal.. my question is, where do i get one, how much is a good one, and do i need one. thanks.....

 

Anytime we put 3 or more screens in a car we use a video amplifier. They really aren't that expensive, I think we sell them for like $30 or $40.....they have 1 in and 4 out, 1 in and 7 out (that's the one we usually use). There are adjustable ones, etc etc. All in the same price area
