My new vehicle has a 14 volt battery, when it comes time to install my amps will I have to install resistors to get a 12v input? Or can my systems run on a 14v input? Would the extra 15% voltage increase give me any significant performance increase? Will I see an increase in power output or am I just going to run cooler because of the decreased current?

Both are alpine, 500W mono for the sub and a PDR-F50 for the type r's up front.

What kind of vehicle do you have with a 14v battery??
It should charge above 16v. Voltage does help for efficiency and power with unregulated power supplies. Korean amps from good companies should be fine on that. Those Alpine amps may be iffy

I'm wondering why the hell they'd put a 14v battery in that. You sure?

Yea, I'm pretty sure, see attached. I think it has to do with the engine stop start feature, higher voltage keeps the starting current lower for less heat on frequent starts, just a guess though.

Is that picture with the engine on? I see RPM's. If so, it's a 12v battery.
12v batteries charge at 14v or a bit higher. 14v batteries charge at 16v or a bit higher.

my escape had a 12v battery and would idle at 12.6v let me look into it some more.

That is not good.
I run 12v batteries, but my alternator charges at 15v.
Unless your Jeep's battery says 14v, it is a 12v battery.
