[medekated]

i have a 2 channel triple rectifer and im not sure which plugs to plug my speaker cables into. my 4X12 cab has 4 inputs the top left one is black and it says 4 ohms the top right one is black and says OUT the bottom left one is black and it says 4 ohms split for stereo or bi amp and that bottom right jack is silver and it says ohms IN. the cabinet says 4X12 4FB CEL-30 combined power capacity 280 watts. can someone help me cause i feel like an idiot. i just know how to rock not how to set up my equipment.
