Is head unit sending audio?
Try connecting direct to speakers. Working? Amp has fault.
Not working? Head unit has fault or is wrongly wired to amp.

Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

there is a black cord that comes with the speaker system with dual end headphone 3.5mm jack both ends that go from one speaker to the other main speaker is your right speaker left is the one with only jack insert the right has da power with sound cord toghether in one going out to amp with headphone insert also that goes to left peaker

dual 2 or dual 4

dual 2 wire vc's in series for a 4 ohm load each. Hook each speaker seperate channels on the amp.

dual 4 wire vc in series for an 8 ohm load each. Hook both + to the right + on the amp and both - to the left - on the amp. or

dual 4 wire vc in parallel for a 2 ohm load each and hook each speaker to seperate channels on the amp.

they are dual 2 ohm all L7 are 2 voice coil per speaker so it is like 2 speakers not 1 the dual 2 ohm version is so you can use 2 speakers wired in series to get a 2 ohm load 2 ohms + 2 ohms = 4 ohms then parralel the 2 at the amp to cut it in half to get 2 ohms. I have full warranties on mine and i dont really sell alot of them any way I prefer the hifonics they sound better last alot longer and take way more power and put out 3 times as much sound. but i can check it out if you have the info.

Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel sound from just one speaker. Simply hook up both the left and the right channels to the special terminals on the speaker. Hook up one channel only, if the speaker is to be used in a conventional stereo set-up.
I found this on jamo site hope that will help you

Did you try to adjust the zoning function to single zone instead of dual zone. If it doesn't work then I think your output chip is fried. You can fix that by adding an external amp. You will get much better sound through a relatively cheap amp, just go with something drand named. Goodluck.

POWR TO BATTERY FOR WHAT?DOES THE SPEAKERS HAVE AN AMPLIFIER? NEW RADIO? SPEAKERS ALONE ARE NOT CONNECTED TO BATTERY ,UNLESS THEY ARE POWERED SPEAKERS,USALLY SUB-WOOFERS HAVE THEIR OWN AMP.iF YOU ARE CONNECTING A AMPLIFIER START WITH A FUSE SAME SIZE AS THE AMP,CONECT 1ST TO THE BATTERYTHE TO THE FUSE RUN A SIFICIANT GAUGE POWER CABLE TO THE AMP.GET THE GOUND FROM A PART OF THE CHASSIS CLOSE TO THE AMP,ALSO SAME SIZE OR LAGER GAUGE WIRE.THEN YOU HAVE TO RUN A REMOTE SWICH WIRE FROM THE BACK OF THE RADIO TO THE AMP.iF RADIO DONT HAVE REMOTE ,CUT INTO THE POWER ANTENNA WIRE .RUIN YOU RCA CABLES TO THE AMP AND WIRE YOU R SPEAKERSMbUT FIRST DISCONNECT YOUR GROUND FROM THE BATERY MOST IMPORTANT.ANY '?'S.WRITE BACK RATING PLEAse.
