Very nice! Now that is what I call putting some bumpty bump in the trunk- how much power is going to the two 10"s
750 watts. I have the JL Audio HD750 amp mount in the package tray below the cargo load floor. I’ll see if I can grab a picture. It fits perfectly. The subs I have (in case anyone wants to replicate the set up are two JL Audio cs110lg-tw1

Yes sir that is the unit I want, I heard that thing slams nicely- have to let me know how it sounds. Do you need to mount it or is it just sitting in there

2 ohms.
For my tastes I preferred the 10” subs because they can play a little lower. Not a huge difference from the 8’s (I tried them first in my previous vehicle).
Channels 7/8 must be connected to the factory subwoofer signal as it contains a needed Low-Pass Filter. Often times when the OEM system has a dedicated subwoofer amplifier, the amplifier will have some noise well above the range of the subwoofer. This is normally not an issue since the subwoofer can not reproduce the higher frequencies anyway. The only time this becomes a concern is when you want to sum the subwoofer signal with the midrange and high frequency channels to have a full range signal. The noise that would otherwise only go to the subwoofer and remain inaudible will now be added to the main speakers and will be plainly audible. These dedicated channels have built in low pass crossovers that help to eliminate the higher frequency noise before it is summed together with the other signals. This helps to ensure that the resulting full range signal is clean and noise free.
Has anyone tried using the Audio 20 Harness that different Amplifier MFGs offer and connect an amplifier with MOST / Fiber Optic input? Also does anyone have the Burmester connector part number either on the cable or the amplifier? Please let me know.

let me know what you end up doing. My foam stuffed between the top and trunk ceiling didn’t really last. The foam has a memory compression and the holding power is kind of weak. The downside is that the subs fall over after about a day or two.

Would anyone be interested in a box that would plug into the OEM harness at the AMP location that would split out all of the connectors and allow you to plug in your own Amp without cutting wires? I have found the connectors to do this. Let me know,

we have already found this connector and posted it above. for free.
I need some help, my outputs are not even. Is this a problem? Can I see your Fix 82 screen shots. Also, I have sub channels on 7/8. I keep getting calibrate errors if I use 5/6. Front left RMS level is 1.13v and front right is 1.48v. Could it be the left wiring? I thought the Fix 82 would balance things out.

I solved this issue. Apparently, you are only supposed to use as many channel inputs (as need), to get a full range signal. I was connecting both front and rear channels and the fix 82 would calibrate fine, but it would produce uneven output. So only front left/right (on 1/2) and left/right sub (on 7/8). Not sure how OP has all 6 channels connected in his picture to the Fix 82.
Now I have two last issues:
1. The AP8.9 turns on fine, but has an delay of a few seconds before audio starts (mute delay?). The OEM amp starts playing immediately and then 7 seconds later the AP8.9 has sound. (this is annoying and I not sure how to fix)
2. My JL Audio ACP208LG-W3v3 subwoofer only accepts 70mv to 1.40v max (on low level), however at 3/4 volume (playing 50hz sine wave), the voltage of the Audison AP8.9 sub preout is 2.40v. Do I simply turn down the channel 9 output in the Audison software settings until its below 1.40v?
