Trouble shooting my wiring?

[sniperslayer]

ok so got all my **** in, all wiring ran, hooked it all up switched on the ignition, Amp lit up, good sign, then started playing music, nothing coming from the subs whatsoever, no movement/sound

Amp turns on and runs fine, so i'm asuming Power/Ground/Remote are all good

so that comes down to RCA's and Speaker wiring, this is how i wired them, on sub "A" i ran the single speaker wire from the amp to both + and -, then i stuck the other 2 wires in with the same ones running to the amp inside the subs terminal, then ran that second wires to sub "B":



does it matter if you use a positive or negative jumper when jumping them like this? with the subs i was given a red jumper and a black jumper (2) with each sub, does it matter which i use if i'm jumping the middle +/- ?

only thing i can think of is maybe the RCA's are in the wrong input in the back of my head unit
