New Amp Making High Pitch Whining Noise

i recently got someone to install a 4 channel amp to my main speakers but for some reason whenever i start my car there is a high pitch whine coming from my speakers, and when i accelerate the whining gets louder and higher pitched, when i have my music playing its not such a big deal because it drowns it out but in between songs you can hear it, and its very annoying. does anyone know what the problem may be?

sure do, faulty ground. Very common in installations. Also may want to check if your RCA cables were run next to your power wire. If so, separate them. Those are the main causes for the "accelerator" whine.
