Hey im new to this site, I have installed at least 10 sound systems (head unit, speakers, and subs) in cars for friends and family. But i recently took a system out of my old car and tried installing it in the camaro i just got its a 92. I have dealt with the wining in other peoples systems and fixed it but my system is doing something i have not previously dealt with and i cannot figure out the problem. Every time i turn the radio on i get a pulsing thump not just when i first turn it on but the entire time its on and it speeds up and slows down depending on the volume of the radio. I have tried it with 3 different amps and 3 different sub setups also 3 different sets of wiring in different spots in the car but i still get the same thing every time. I know all of the equiptment works because its all stuff i was previously using in a different car. the only thing thats different is the head unit which came with the car but that is new so i dont see how that could be the problem. it also sometimes makes a weird almost like a squeeling noise similar to the sound a record makes when you move the needle on it. Any help would be GREATLY appreciated.
