Ok so i wired a GT-50 into my 09 scion xB im just running the fronts for now, Do i have to have the 2 powers and 2 grounds hooked in order for this amp to run? I only hooked 1 set of these I havent seen it turn on, iwent to the store got a quick disconnect for the remote wire still nothing. Im a little upset at the moment, i spent soo much money on my amp kit i could barely use it because of this amp someone please help me out. Thanks
