Mosley_23 Posted August 28, 2017 Report Share Posted August 28, 2017 I installed a lc2i and a new kicker kx 400.4 amp and at low volume I can hear a hissing noise it don't get louder as my volume goes up. When the radio is turned off kinda like stand by mode it goes away but when I turn my turn signal on it comes back until the signal goes away. My ground wire is super clean but my ground wires are around 4-5 feet long l Link to comment Share on other sites More sharing options...

Mosley_23 Posted August 29, 2017 Author Report Share Posted August 29, 2017 Gain was midway from the lowest point to the half way point. And I think it might be coming from the lc2i. I shortened the ground to double check and it's still there. If the gain is all the way down it goes away. I disconnected the rca cable going to the amp and it went away. Could it be caused because I have the power and ground coming from the amp to the lc2i? And my local car audio shop only tapped into one speaker and used a jumper to fill both inputs on the lc2i Link to comment Share on other sites More sharing options...
ShadeTreeMechanic Posted August 29, 2017 Report Share Posted August 29, 2017 I have my gains down and use a preamp to drive the line for this reason. I would take it back and have them wire it into a right and left speaker so you can have true stereo sound. The right and left are both needed and must not be wired together. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
