Hello Guys,
I just bought a sub box off a guy and it comes with a AMP, I have a Pioneer 1300MP Unit in my car and a Kenwood amp kac-9105d - 2x kicker subs.
I hooked up the ground and the Power wire, along with the blue wire from the deck, an the AMP powered up. From behind the deck I have 2 output and I connected the RCA cables back there to the AMP input. Still no sound. (The deck do play the other speakers fine)
I then used the 1/8 Jack on my iPhone to RCA an connected it to the amp's input, still no sound from the SUBs... I just feel as if my issue as to do with me not understanding how these work 100% haha
Thanks for any help :)

If your system moves you physically and not emotionally, you have wasted your money.

Yeah, I read it over and realize. My apologies, I was trying to get too much thoughts out at once, while at work

Solder a wire to the shield (The outer part of the RCA plug of the adapter) and ground it.
