So i need to replace my starting battery with a deep cycle for the stereo. I have kinetiks in the back but wanted to try out powermaster, and i heard that AAP sells them so i went by to ask what size i needed so i dont have to deal with unhooking the stock one just to measure. So i go in and the guy tries to sell me some battery, i told him i didnt want it bc i needed a deep cycle because otherwise they would charge at slightly off voltages and drain each other. He asked what i had in the back and how many watts. i told him im putting 3 batteries in (Kinetik HC2400) and about 15000 watts peak, since i KNEW that was gonna be how this guy measured amplifiers. He fucking asked me if i had ever thought about getting a CAP because i wouldnt need any of those batteries. He went on FOREVER about how great caps were and how if my batteries were charging at any diff voltages it was because i made all horrible connections and that it was guaranteed i'd lose voltage anyway since i was adding more batteries?! what the fuck?! i let him keep going because i thought it was funny but what an idiot
