Okay so I've got everything for my new setup ordered except for batteries. I had ordered 2 nsb90's but they informed me today that it would be 45 days before they even had them in stock and I can't wait that long. So I was wondering if 2 d3400's would be enough to power a soundqubed 3500.1 along with the battery I already have under the hood. Anyone got any input on this?
