Yes........maybe the ground is poor,pin jacks broken ,open ground in the preamp stereo ouput...all for the ground..try this........ take a pice of wire and put one end in ground of car chasis in area with no paint, and the other side in the amplifier input pinjaks and check if the static goes off. good luck.!!!!

How To Diagnose No Sound Output From Your Vehicle Stereo

  1. Check each Subwoofer or Speaker that isn’t working for continuity - At the subwoofer or speaker, one at a time, test the terminals for Continuity using your Digital Multi-Meter; if your DMM doesn't have a Continuity test, use the Resistance, or Ohms, test and check for Resistance in the Subwoofer Coil (be sure to disconnect the subwoofer wiring before performing these tests).
  2. If they test out good, hook the wires back up and test the terminals at the terminal cup or at the Amp hookup if you didn’t use a terminal, don't hook it up to the amp yet. Sometimes the wiring inside the box can be a problem if it has come loose, or isn't making a great connection.
  3. If you have a Sub or multiple Subs with Dual Voice Coils, or multiple Subs with Single Voice Coils, make sure your wiring is correct by checking here:
  4. Make sure there are no Hi-Pass filters, crossovers, or multi Channel switches enabled.
  5. Replace your RCA cable/s with known working RCA cable/s from the Source/Head Unit to the Amplifier/s.
  6. Check your Head Unit settings; make sure the Bass is turned up and/or the Subwoofer setting is turned On.
  7. If you are still getting no output, try plugging in an MP3 player or CD player using a headphone to RCA adaptor and check for sound output. If there is still no output, your Amplifier outputs are probably burned out.

Subs hit without volume on

1. Check Grounding system (Player and Power Amp).
2. Ensure your RCA cable is OK
3. You might adjust volume or bass volume on power amp to maximum, just set all to 50% while you are tuning.
4. Check the speaker out cables might contact the ground/ chassis

I have a few problems. i have 2 amps and 4 subs. first problem is when i connect one amp to my speakers it just hisses and crackles. this never happened before. when i turn up the gain to try and get...

The first amp, sounds like there is straight power going through the gain instead of it being limited. The second amp...hook the other subs up to it and see if it sounds ok. If so, then the subs are messed up. If it sounds the same, make sure the subs are connected correctly.

Kicker sub wont work

Im guessing that it is possibly blown... either you ran too much power to it, or it was hooked up wrong... you should unscrew the sub from the box and look inside to make sure that it is connected correctly.... positive to positive, negative to negative,,, if they so much as touched then the L7 could very well be blown.... smell the magnet and if you smell a burnt smell... it is blown... maybe turn your amp down a little... its possible that it is also in protect mode because you are running too many watts to the amp. Feel free to ask if you have any other questions.... Please rate! :D And good luck... i really hope its not burnt out. that stuff is not cheap.

If you are unplugging the subs from the aux output at the cd player, your Audio lines feeding the amps is shorted somewhere between the cd player and Amps.
