So heres my question.. If you have a high end battery charger, why should you get a HO alternator. I understand that your system draws its power from your reserved power (batteries), and your alternator justs recharges them. If you use your car as a show car or only play your music primarily when your in park and engine is off, and you have a big battery bank, do you still need a HO? Cant you just plug in your charger whenever you need be and recharge your battery bank without any damage to electrical system. Granted, lets say you do drive around 15-30 minutes daily and you play your system loud, will not having a HO for this short limited of time damage electrical? Any and ALL comments are welcome thanx in advance!
