side note, both batteries read 12.7x on volt meter with engine off (without putting on trickle charger).
Thanks a lot for helping me out!
A "house load" is anything you want to run when the engine is off and have it draw off the newly installed "house bank"
Your head-unit should also be connected house bank. Odd are, its drawing off the cranking as it originally was.
