Replace Factory Alpine Sub???

[jeepguy_1980]

I have a JL Stealthbox from my '03 and would like to swap out for the factory Alpine sub. But in looking at the at the wiring diagram, each voice coil has its own signal. So, I'm not sure that an LOC would provide a full spectrum signal to any amp that I add. Does anyone have details on how they wired their aftermarket sub with an Alpine system.

Also, what did you use for a remote turn on? I'm not interested in a switched accessory signal, nor am I interested in a line sensing trigger. I have reviewed the factory amp and see that it does not have a remote amp trigger. The factory amp is instead connected to the CANbus, which tells it when to turn on and off.

OPERATION
The amplifier receives fused battery current from a fuse in the Power Distribution Center (PDC) at all times. The internal circuitry of the amplifier switches the amplifier on based upon a CAN-I bus message that is received from the Radio Receiver Module (RRM) whenever the RRM is turned on. The amplifier receives the sound signal inputs from the left and right rear outputs of the RRM, and then sends the amplified speaker outputs for each of those channels to the speakers.

The amplifier receives information from the Body Control Module (BCM) and RRM, that communicates the correct channel setting for optimum speaker sound and output.

There are two amplifiers available, an 8 channel, rated at 322 watts (7 channels are used) and a 12 channel (11 channels are used), rated at 506 watts.

Here is a harness I made, that I hope to be able to use to feed an amp or LOC.

nice. I just used the same plug feed to mine to my line level converter then to my amp for my sub. I just ran a wire for the remote wire to my Aux panel in the dash.

so it's not just a drop and swap? seems like a lot of extra wiring going on here..

I too have a stealthbox from my 04/07 ram's and was thinking about putting it in..
