AC-LGD with 500.1 AMP

[kuee95]

I bought the Plug and Play harness 19-1. Got everything installed but the sub does not sound good. Can't do the setup for the 500.1 either. I never hit the limiter.
Attached is a picture of the AC-LGD. It looks to be wired backwards, right? According to the AudioControl instructions the left side is the input and the right side is the output.

The wires going to the amp are the Gray/Green/White/Brown.

I'm also having to use the Low Level input Option on the AMP to get any sound out of it.

It does not even seem like the connectors were swapped does it. Because then + and - would be swapped.

I just got the exact same kit from him a few days and it sounds stellar. Try unclipping the screw mounts and swapping it the other way (they slide right out)

Then + and - would be reversed. Don’t want to blow anything up.

You should be able to run the 500.1 without needing the AC-LGD at all.

That is just a resistor bank so that the OEM head unit sees some load and won't throw DTC codes. It will also lower the input to the 500.1 - which is why you are needing to use the Low-Input option on that amp rather than speaker level.

It really shouldn't matter which end you wire to what - there are no diodes or anything as far as I can tell, it's just some resistors. That said - here's the official installation instruction:

If I use fader fader on the Bronco and set it front left or front right I get great base out of the system. Otherwise it’s very limited.
Does that mean I have A setting Wong somewhere?

Sounds like it’s just looking at the front channel - which is typical. It should scale somewhat linearly as you slide from front to rear though - not nothing nothing nothing then BAM you have sound at full front

If I adjust full left for instance and dial front to back as I get further back the bass drops off. I guess that makes sense if the LGD is tied to the front speakers. What doesn’t make sense is that adjusting left and right it makes it change.
it’s almost like left and right are canceling each other out.

Could be one of them is wired backwards
