[QUOTE="HardofWhoring, post: 8837142, member: 674149"] What is going on in here? 1500w is a little over 100 amps. You DO NOT need a second battery. Unless you need a bank so you can run your stereo with the vehicle off, one battery can handle that demand just fine, and your alternator is larger than you need. OP is not running 5K watts, they have a 1500w amp. OP so you have two subs that area 1250w RMS each, and one amp to push 1500w to both? You need another sub amp. You could get a matching sundown amp, but I wouldn't. Don't you need a new sub amp that will push around 2500w or a little more? Optimas are not junk, and they carry a 7yr warranty which is longer than anything else on the market. ONE AGM would be fine pushing a 2500w amp but we're getting close. You didn't say what vehicle it was in, or what else is going on with the other amp. For a larger sub amp, and another component amp, your 270 amp alt is perfect for. [/QUOTE]
