If you just want to add some bass to the existing sound system, a powered sub will do the job nicely. Dealers off course will try to sell you a much more expensive separate set, but I think that's overkill in this case.
If you're planning to upgrade the whole system over time, you better look out for a complete separate system, as part of the master plan.

I am building an active sub myself at the moment. Home-made amp, home made active filter and rather small 8" but decent kevlar woofer. It's gonna be 80 real watts RMS into 8 ohms. In fact I build a sub that fits in the "secret boot compartment" and put all electronics inside of it. The cooling block will be placed inside close to the bass-reflex opening, or on the outside. Not yet decided.
I am wondering though where to get the input signal from, since the standard stereo has no pre-out. Probably have to take it from the speaker out. Not the best solution, but ok for subwoofer input.

BTW, where does the concert pack get his input from? Anyone has an installation manual?
