[QUOTE="iDesignBoxes, post: 4158410, member: 587212"] Amps that are rated at 12V are usually underrated because your car runs at about ~13.8V when idling... so the increase in voltage actually gives you extra power. They are rated at 17.7V so they can advertise "1500 WATTS" and this is done to trick the consumer to believe that they actually do 1500 watts while the car is operating at ~13.8V, rather than the actual 17.7V. In other words, a MAJOR decrease in the rated voltage compared to the car's actual voltage is quite significant in relation to power. [/QUOTE]
