Need help with jumper pins on LC2i.

Ok I installed it today adjusted the gain until flickering stopped (12 o clock) and accu bass cranked. Only problem is when I use addon remote knob and bass is high stereo off I can hear a hum from sub unless I turn the gain completey down on remote knob or turn gain down even more on amp

I was thinking about everything you sent me. I'm going to check it out tomorrow, I've been caught up with this other car.

Turn accu bass off, your basically pre clipping the signal with that.

Does that mean then I can't use the remote knob no more if accu bass is turned off.
Big do you know what the max voltage for rca input on the alpine mrp2000 ?

Remote knob should still work. Max input voltage for rca is printed on your gain control dial. Typically they are 8 volts, but there are exceptions.

Talked to alpine tech turns out max voltage input is 4volts.
Does that mean lc2i shouldn't be putting out more than for volts. To measure I put dmm in ac. Is that correct? Could be the reason I get humming noise when stereo is of but the remote knob cranked up.

Turned the gains down on lc2i. When I in plug the remote gain knob humming goes a away but when I plug it back it comes. Any one recommend different remote gain knobs. Looking to put it in between the heated seats switch on centre console have an empty slot
