If you have amplifiers with a regulated power supply, then the slightly lower voltage doesn't affect your system at all (if like you said you have the amperage behind). Best regards from Munich Bari

Hello, noise is mostly produced by a bad ground or high frequent noises from the alternator. Have you a additional ground on your alternator? Your bracket doesnt look like in best condition. Have you done the big 3? Can you test a other ground point for your amplifiers? Or a direct connection to batterys negative? Best regards and good luck

Thanks for the video man! The turn-on rpm / idle output is a very important thing. You are right that bigger are not automaticly better. I have also "only" a 180A/200A HO Singer (stock 90A) with stock pulley. Since there is no speed limit here, its good to can drive with >155mph and dont need to worry about the alternator. Optima is good choice, have it too. Best regards from Munich Bari
