I'm in the process of building my third system, but it's going to be my first REAL SYSTEM. I'm limited on space for the simple fact it's a daily driver. I'd like to have 16 Volts running to all my amplifiers for maximum power efficiency. That being said I know my alternator will have to be charging at 18+ Volts. I have a 1999 Oldsmobile 88 and I'm wondering will the 16 volt battery(ies) fry the factory systems? If I were to keep the standard car components on a 12volt battery would the 18 volts from the alternator fry that battery and possibly the electronics I intend on protecting? I've seen some 12/16 volt batteries would I still be able to charge the 12 volt section with the same 18 volts from the alternator or would I need a second regulator for. All logical and helpful input will be appreciated.
