well, it looks like the subs are just a single voice coil, do you have them now? or did you just order them? tell me if theres only 1 pair of terminals to plug the speaker in or if there is 2 pairs.
i didnt see what you wrote about using 14g wire as your power wire, im sure that was your problem right there. wait until you get a 4g wiring kit, that 14g wire is very prone to fire if you use it for your amp. and make sure you fuse all your + wiring connects to avoid fire incase a short happens. and another thing, always disconnect your battery when screwing with any electrical wires, you could seriously damage some shit if you dont know what your doing
no problem man, ill be happy to help you out anyway i can
