I got this stereo from my dad and idk if it came like this or not, but the two speakers aren't connected to the main thingy. The wires are color coded, but when i plug them up, they dont match? and the wires are open ended, so you have to tie the prong-string-thingys together. sorry for my stupidity:

Main thingy: 2 sets of 2 wires; both sets have one black and one red wire

Left speaker: 2 sets of 2 wires; first set is black and red; other set is blue and white

Right speaker: same as left

instruction manual doesnt say anything about connecting the speakers. thanks!
