I just got to vent. I get so tired of repeating to people how to properly set up systems, what ohms are, how to hook up things lol. I'm in the army and everyone in my unit knows I know my stuff, I sold my AQ HDC3 12 and my brutus to one of my sergeants and when installing, he screw the amp down on the floor board of his truck and said, ok its grounded now. I said uhh..no screwing it in does not ground it. Also, the hooking up of speakers, ok if I have a D2 sub, i only have SO many options to hook this up but man these guys all wanna hook up one coil or run em off 4 channel amps, what the hell...lmao... man o man it never gets better...
