Posted July 26, 201114 yr I'll start by listing all the equipment used in the vehicle (2008 Dodge Caliber) and say that all of this has been installed and working fine for months until tonight. Starting up front, we have a 230amp DC alt, hooked to a factory replacement Duralast battery under the hood and the big 3 in 1/0. There's a fused power wire running from said under hood Duralast to Kinetik 1400 in the back near the amplifier, then on to the amplifier which is a Hifonics bxi1606D wired to 1 ohm. This amp is powering a pair of D4 Skar VVX12s. Now on to the problem, tonight we started the car and immediately noticed a sound/noise coming from inside the amplifier on the power/ground/speaker terminal side (it's louder on this side when listening to the noise anyway). I unplugged the RCAs and the noise continued, so I plugged them back in and unplugged the knob, the noise was still there so I plugged it back in. Then I loosened and unplugged the remote wire which of course shut off the amp and killed the noise, then I put the remote wire back into the amp (car still running) and the amp turned back on and lit up, but the noise was still there, so I pulled the remote wire for now.The noise sounds almost like a small electric fan, I'm not sure what it could be, I'm just looking for some suggestions before I open the amp up and check it out further. Has anyone experienced this before or have any idea what is making the noise and why?
