With a stock 120amp alt and stock battery, I could do 1300w with a .4v drop in voltage. Before, it went down 1v. Trust me, those grounds WILL make a difference if you have stock grounding wires.After an upgraded battery, my drop was a bit less. Also, If your still runnning the stock battery, a better duralast/everstart/ or better yet a sealed Kinetik/stinger 1800 would help you out<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
