Welcome to the world of subwoofers. It can be alot of fun and hopefully we can help you get what you want avoiding the money traps we fell into.
If on a budget, I suggest checking your local Sunday ads. Your local Pep Boys/Kragen usually have those dual 12" subs with amplifier kits for about $100. That would be your best bet to start and install it yourself. Also for $100 it's like buying a toy to play with and destroy with bass, while you learn what you'd like best out of a sub. Accuracy or agressiveness? It takes alot of money to get both.
A friend of mine one purchased a Visonik package a few years ago and we're running it's included amplifier out of spec, bridged at 2 ohms, and when the levels are properly set, it surprizes many people for the amount paid.
You can install it yourself. Many of them come with very basic wiring. I suggest you skip on the power wires it comes with and purchase 0 or 4 guage power wires. It's a chore to run that wire from the hood, so might as well get it right the 1st time.
I assume you're using the Mercedes headunit. If so you'll have to sacrifice your rear speakers to feed a signal to your sub. Don't spend money on LOC (a converter), just be sure that the amp included with the package accepts speaker level inputs. (most do) If you do have to spend money, then buy a decent headunit with sub outs.
After installing it, go easy on the gain level, usually set the crossovers to the lowest and resist using any bass EQs. More likely your lights will eventually dim when the bass hits. Avoid the capacitors for now. You'll need to upgrade the Big 3 wires, which is highly recommended for your cars electrical sake.
Then more likely you'll be yearning for more bass. You can still keep the dual 12" and just upgrade the amplifer.
I believe, that's too far already.
Have fun and let us know.
