Disconnected my bass (Alpine swd-355) because I needed the cargo space. I should never have done that. Now I can't get it to work again. There are not many wires that have no "home". But all the combinations I have tried are not right. I am attaching pictures.

Picture 1 shows cables going in and out of the box (Where the amplifier is also located). The Amplifier is an Alpine MRV-M250.

Figure 2 shows cables connected so far. All wires to ground are where they have always been.

And Figure 3 shows the cables that I have no real idea where to connect them.

???

I have One thick red cable coming from the car-stereo. You can see the cable in the second picture. The thick brown cable next to it is ground. And the thin blue cable next to them is remote.

Then we have the thick blue cable coming out of the subwoofer (picture 1). That is Left/Right from the Amplifier.
That cable connects to the small "converter"-box and turns into a larger number of cables (shown in picture 3), mostly blue. One of the blue cbale connect by itself to ground. And then there is the brown cable(Nr.1 in Picture 3)?

I have some memory that you need to connect one of the loose cables in picture 3 to the thick red cable in picture 2?

That would be the Yellow wire from the LOC. It has to have constant 12v.
Use the color chart above to identify each wire on the LOC. I do not see Brown in the chart and I do not see Black on the LOC, so I assume they are one and the same.
Thank you for the help. Now I finally understood :) Bass working fine now :) Life back to music ;)

Yes, the power wires' colors don't match from the dash to the new harness. However, I tested them and the wire I'm treating as the constant 12v is...
