[QUOTE="Seth F., post: 8718695, member: 680868"] Skar is not a bad brand. Just everyone hates them on here for whatever reason. I am running two Skar amps in my truck right now and they are just fine. For the money they are worth it. You can do some math to figure out your amperage requirement as well. Its basically I = P/V where P = total wattage and V = voltage of your vehicle. Typically V is 14.4 so in your case you might have I = 2400/14.4 = 166.6 AMP @ 2 ohm or I = 1400/14.4 = 97 AMPs at 4 Ohm. The last part is the efficiency. If you average an 85% efficiency into that equation for both amps youre looking at 166.6/.80 = 195A at 2Ohm or 114A at 4Ohm. But that is at MAX volume when you are running a Sine wave through the system (i.e. a 40Hz signal). So those are worst case burst scenarios but that gives you an idea of what to expect in terms of current draw. So you may want to at minimum invest in a Group 31 or 34 battery to help out. [/QUOTE]
