I'm sorry to ask the same question but i've searched and i'm still stuck.
i have a Kicker 07DCVR122 (2) 12" subs 2OHMS in a box and a Kicker KX800.2 AMP. I also have the LOC:

SVEN2 2 Channel Premium Sound Interface Device


I've done everything to where the amp gets power, i did the remote wire, ground, power from the battery, and I connected the LOC through these instructions from a member on here:

1. twist the 2 positives together.
2. twist the 2 negatives together.
3. remove side pillar next to the passenger seat.
4. tap into the right rear speaker door via side pillar. see pic.

5. connect twisted positives to red/yellow wire. (+)
6. connect twisted negatives to brown/white. (-)
7. connect and run rca wires from LOC to amp.
8. complete wiring up your amp to sub/battery/ground/remote
9. turn up the volume and enjoy your work!

then my problem is running the wires from the amp to the box. there's a + and a - on the box.
I've tried bridging and what not but no sound comes through the subs. the loc is set to take in wired and RCA out. It looks like everything is connected but there's no sound
Please help me!!!
