Well, I got the Cleansweep installed in my Volvo this weekend. Along with two amplifiers.
I was holding out on buying it but my wife got tired of hearing me [censored] about the sound so she went out and bought me one.

It is very easy to hook up, assuming you've got wiring schematics and know what wires to hook it up to.
I've got to give them props, it is a very clean sounding item and it has a few cool features.
If your stock deck doesn't have an AUX/AMP turn on wire, the cleansweep has an amp turn on and there is a signal sense switch that will turn the amps off when there is no audio signal sensed on the speaker inputs. This helps out so that all you have to do is hook it up to switched 12v and if the radio is off, then so are the amps.
the volume control comes with a silver or black knob and it matched my Volvo brushed steel trim perfectly.
The knob allows an auxilliary input such as an ipod or mp3 player and you just push it down to switch over. Now I have all the music I want on top of the regular stereo.

So it is clean and quiet with no engine noise despite being spliced inline on the factory speaker wires. Fortunately Volvo uses true 14 and 16 ga wire for their speaker connections so I didn't have to replace all of it. I used 18ga to go from the where I tapped the speaker harness to the cleansweep and then 16 ga from the amp back to the splice.

I ended up buying Bostonacoustics Pro60 speakers for the front and just finished installing them tonight, but no reviews for you guys yet.
