So what's the big deal with your stock alternator? NOTHING AT ALL. When installing aftermarket 12 volt equipment in your ride, the heart of the system becomes less efficient at supplying those devices with adequate 12 volt current to allow for optimum performance. An OEM alternator averages a peak supply potential of 120 amps. Some vehicle's stock electrical devices pull as much as 100 amps of current, leaving the alternator onlly a small amount of leftover current to throw at your brand new 5,000 watt amplifier that needs over 400 amps of current. The math doesn't seem to work well, does it? Too many consumers leave so much power on the table by forgetting to feed their amplifiers and other 12 volt devices the current they so strongly crave. Remember, operation and performance are two different things. Feed your system with higher current by clicking HERE to examine our selection of High Output Alternators courtesy of G2 Power!
