Works awesome! My voltage barely moves and I swear my amps are making more power! Just make sure you connect it right ! Positive to positive and negative to negative for correct parallel wiring and it will work awesome! And also makes a huge difference having a high output alt , I have a brand x 400 amp and group 47 AGM main

Awesome battery, my voltage barely moves and it is easy to hook up , just connect the red positive to the red positive of your under hood main AGM battery and connect the black negative to the negative on your main AGM battery! Easy my amps are definitely putting out more power now ! You can literally hear the difference and no more clipping!!
