Ok, I think I got it all right.

I took a speaker wire and split the two leads. I ran the single wire from the console, through the firewall, and put an o ring on it and attached it to the battery terminal. The heavy duty marine cable already has a built in fuse box right next to the battery as well. I connected that to the battery terminal as well.

I disregarded the original brown, mercedes ground. I removed the ash tray and the center console and screwed the ground from the new wiring harness to the bolt that attaches the shift knob.

I spliced the antenna and the remote line for the amp and put them together as well. That one was black off the back of the Becker, but when you peeled away the first black rubber, you can see that it is actually a blue wire with a red stripe. I ran the red as the ignition 12v and the speaker wire to the battery as the constant. I plugged it all in this morning and it worked like a charm. Antenna went up automatically when I turned on the head unit, and the amp powered up at the same time. I didn't blow any fuses and all the lights and wipers and interior lights and warning buzzer all still work too.

However, the subs aren't making any sound. I'm hoping it's a setting on the HU that I have to "turn them on" or something like that, and not that they are either bad or wired wrong.

My set up is 2 Planet Audio 100w 6in speakers in the rear shelf, 2 4in Kenwood 3way 120 watt speakers in the dash, I have a US Amps Xterminator 1600.2 Amp running 2 10in 200w Jenson subs, and I have a Pioneer DEH-1300 head unit with a remote and Ipod/accessory on the front input.

I bought a monster wiring kit that came with the huge marine power cord with the fuse box built in, a huge marine grade wire for the ground, nice thick wiring for the subs to the amp, the long remote cable for the amp, RCA cables, and zip ties. I also bought 50 feet of the brand below monster (can't remember the name) of speaker wire and used that to run the four speakers and the constant power.
