Can my 914 run on a 14v battery?, Will it tolerate it? Options

I'm into my hi end car audio and I have a 14v agm battery - would I be able to use this in the 914?

It's been a while since I've had a -4, but if your voltage regulator is the
old mechanical type, you can tune it to 15.5~16V by bending a tab.

Really i'd like to know more...

To all those that don't believe - yes amps make heat, of course they do, but they are also far more efficient with a higher voltage input, so the effort involved in getting a couple more volts input is well worth it.. When the alt is running in a car the battery is basically not used and the voltage supplied is (from the standard alt) 13.6 volts - shut the engine down and the voltage drops instantly to 12.5/6/4 whatever your battery is capable of. If you are involved in sound competitions as I am, keeping the voltage up is really important as the system is judged without the engine running, so the better the voltage supply and more constant the better. Going off topic slightly, some people use caps to keep the voltage from dropping, but you can tell everyone yo know that these are a waste of time as the problem in a car audio system is always the wiring to and from the battery - If the lights dim then it is most probably the negative wire because it is of a smaller awg to the supply wire, therefore causing a bottleneck in the circuit. Put a cap in and yes, it will supply the power needed, but the old wiring circuit still needs to supply the cap with its power, and through the smaller negative wire it will still struggle to circuit properly. So anyone that has a cap that says it improves their sound system you can now inform them of their weaknesses!

Anyway back on topic - a very interesting discussion has evolved and I look forward to other opinions... Oh and to the other nutter with all the Phoenix Gold equipment in his car - I now have two McIntosh amps in the car, ID horns and EMIT tweeters - Sounding amazing!!! Better than my home hifi (IMG:style_emoticons/default/piratenanner.gif)

You just motivated me to start my "NEW" Phoenix build thread.
