I just installed the J/L 500/1 amp with LOC.
I got the Loc from tweeter and they said it should be good for the G35.
I installed the loc wires(++--into Blue,teal, Pink,purple) before the factory AMP(i have BOSE system) in the trunk.
when i connect the sub, there are voice in the sub.
Does any one know how I can get the voice out. I just want the bass only.
I know when i connected to my 300z i can hear only the bass but it does have a sub out and the HU in the G35 does not.

thanks

Is the cross over on the amp turned on. Set it to lo pass and set the frequency around 80hz or so and just play with it until you get the low pass frequency that sounds best to you.

 

turn the HP/FULL/LP selector on the amp to LP, and then set the freq to about 80HZ
