hey, im about to order the audiobahn A2300HCQ amp which is rated at 2300 watts. im also gona be using another 400 watt amp to push my highs. Im wondering if i would need to get a new alternator or will a cap and battery do the work just fine?? With that much watts involved, im worried that the amp would draw out all of the power from the battery. Any help would be greatly appreciated. THanks AGP
