Alright I actually like the standard audio system in the X5. I think it performs better with the mids and highs than the HK in the E46.

However, I would like some more accurate reproduction of the bass in the cabin. I've pretty much acquainted myself with the various options:

--> Separate boxed sub + separate amplifier
--> Replacement of mid-range speakers in the doors
--> Infinity BassLink self-amplified subwoofer
--> SAS Bazooka self-amplified subwoofer

First of all, let me state my intentions. I don't want to create a system that's gonna be heard outside of the car;

I also want to stay away from replacing existing speakers - that's a mess which I can't justify to pay for, nor cope with.

This leaves the BassLink and the Bazooka. Well, according the BavAuto they only sell the BassLink if you have the DSP. Supposing this is true, that unfortunately throws away my first choice.

However, a famed Toronto audio shop told me about the SAS Bazooka. I am aware they aren't as "good" as other high class subs. I just want to accentuate the bass in the cabin, and at 100W RMS power, I believe it's sufficient.

What are your opinions on this idea? I was quoted $500 including installation (about $410 US).
