Many racers run 16 Volt dual tap batteries (12V/16V) They have a 12V tap for the car electronics and a 16V tap for spark control or amplifiers like yours. They do require a voltage booster for normal charging. The voltage booster mounts in line with the alternator output. You will need around 16V just to keep your 14V battery charged. You could also have a custom alternator wound for higher voltage. Then you would use a resistor network to drop voltage to the vehicle electronics or several diodes in series. A typical diode will drop 0.7 volts in the forward bias. Most amplifiers, yours included have a voltage range. Usually 10-14 volts and will work fine within that range. 14 volts will net higher output wattage than 12V.
The real question... Your amplifier may be more valuable that your 914. Do you really want to install it in a car that spends most of its life on jack stands? (IMG:style_emoticons/default/poke.gif) |
