[QUOTE="TrillGates2k6, post: 8246328, member: 660335"] Well the amp you picked pushes out 3,000 watts if you look at the specs; I'm not sure if you planned on pushing it that far or not, but it has the ability to do 3000 watts; So i would just assume if you bought it that you would want it to do what it's rated to do. But if you're only looking to do 1500 watts, then you'll find that you need a lot less power coming from your alternator; I don't know if your car is a 4 cylinder or a V6; But if you have a 4 banger, then you have a 70 AMP Alternator; And if you have a V6, you have a 130 AMP Alternator; So we figure that your car uses about 45 AMPS to run the vehicle; So we subtract 45 from 130; That leaves us with 85 AMPS to work with; Your vehicles voltage is gonna jump from about 13volts to 14.4volts while you're driving it; So I usually use 13 volts to do all my math so i can get the worst case scenario; But anyway, 13volts * 85 AMPS = 1,105 WATTS; That means that without any modifications, your current vehicle setup from the factory can support about 1,105 watts of music; HA HA HA, yeah right, that's only assuming that AMPS are 100% efficient, which they are not; So we assume that amps are about 70% efficient; So we multiply by .7 So your current car's alternator, battery and wiring is probably good for about 773 WATTS. The first thing you want to do is at a minimum do the big 3 upgrade; you can look that up and find out what it is; Also you wanna look at getting an upgraded alternator; They call them HIGH OUTPUT ALTERNATORS; They're expensive, but hey, you're playing with the big boys now; [/QUOTE]
