Hey guys! Time to get busy with the girlfriend's build again! Today we'll go through the steps on how to wire up 2nd battery in the trunk of our 3,000 watt car audio install :) The results were pretty impressive with our fresh Turbostart and stock battery compared to JUST the single Lithium setup - so be sure to watch till the end! AND... Congratulations, KNIGHTLIFE95 for winning the ULTRACAPACITOR hook up from the Showtime Instagram page!
