hey guys i just finished replacing my front component speakers that were bad with new ones. Im running infinity kappas in the front and rear and they are hooked up to a 4 channel alpine amp. Before i replaced my front speakers i didnt have any hissing in the speakers but now all 4 do. I did move the amp while replacing them but i used the same ground and everything. I also ran new 14 gauge speaker wire up to both doors when i replaced the speakers. I unplugged the rca cables from the back of my headunit and the speakers still hiss. what should i look at next. I also made sure the amp was grounded well. This is really starting to frustrate me. any pointers would be great. thanks

 

any ideas???
