I've been happy with just a "working" audio system, but now I want it clean.

Any suggestions?

This is basically what it looks like, but imagine the distributor shoved under the cargo mat and another 8awg and remote going to the center console

Also: I have 8awg and remote wire (not pictured) going from the distributor (pictured) to the center console for the HPF amp, and would like to know how to hide those wires. I assume I need to take the seats out and fish it under the carpet.

 

You may be able to leave the seats in and simply remove the trim from around the edges and pull the carpet up there if you have room for the cables. You could put the box inside a display box that you make or buy and put some lights in it or something for a flashy look.

 

I tried lifting the carpet up and it's glued to the floor or something.

And I'm not going for flashy, just clean/neat
