Message: <blockquote data-quote="BoBdOg" data-source="post: 1537106" data-attributes="member: 604712">I have wired my amp to the battery with the fuse etc, i ran the remote cable to the back of my aftermarket head unit and the rca cables from my amp. I then connected my sub to the amp but i get nothing from it! The only time it works (poorly) is when i have the RCA cables both positive and neutral half in/out at the head unit. Then when i mute the music it makes a loud humming noise. Can anybody please tell me why its doing this? Everything i am using is brand new!!!I am also using a capacitor, worth it or not?</blockquote>
