New member Username: CbanzetPost Number: 1 Registered: Aug-06 | OK guys i just started my truck and i have a loud hum coming from my 12w7. I dont' push my amp and subs that hard. So i have no idea why i would have this problem. I checked all the fuses and they were fine. I checked the Ground wire and it was good. I disconnected and ran a new pair of inputs and still got that hum. I disconnected the capacitor and ran it directly to the battery and still got that annoying hum. Any ideas? Has this 1000.00 amp crap out on me? I am out of ideas and unfortunately the warranty has ran out on this amp. Anyone have any ideas on what could be the problem? Thanks |

New member Username: CbanzetPost Number: 3 Registered: Aug-06 | The grounds are nice and sturdy connections to bare metal about 6inches away from the amp. I took out the inputs while the stereo was on and the hum is still there. No music just straight hum. And it's annoying. |

To test to see if its your headunit Get a wire like this  then plug one side into an ipod or walkman or w/e and plug the RCAs into the amp.. play a song on the ipod or w/e and see if you get any output. If you do then the problem is your headunit not your amplifier or the wiring. |

New member Username: CbanzetPost Number: 5 Registered: Aug-06 | Well i just re-grounded the headunit. Still no fix. I did everything you guys told me i should do and still that F****** buzz. Everything is grounded right, I checked the power wires, bypassed the capacitor, changed out the inputs, changed out the remote wire and i am under the impression that the amp needs to be serviced. with just power, ground, remote power and speaker wires hooked into the amp i get that buzz. NO INPUTS WERE CONNECTED TO THE AMP. So no signal was getting to the amp from the headunit and i still got the humming sound. I even jumped the remote wire to the power wire on the amp to see if it was the remote wire on my deck that was causing this. And surprise....it didnt' work. |
