Power: (Polo 6R) in the spare wheel well (equipped with me without a spare, but with styrofoam and tire weld) is tinkering and connected properly it reaches the turning up the gain on the 60% mark (disconnected bass boat) and turn up the bass on the EQ the original radio a pressure which makes the installation of a massage seat seem pointless. The implied by electronic dance music youth disease "hearing loss" there on top of it free.
A fully turning up the Gain plus switched on bass boat and Equalizer on max. I would not recommend even at medium volume. Unless you feeling the urge her / his ENT doctor to want to get to know better, but then only with sign language.
Sound: separated from the chassis (in my case through the existing and rigged Styrofoam), he does not generate a rattling or chattering and brings the bass nicely into the interior. He feels most comfortable, however, in the area of hip hop, lounge or House.
Should to achieve the ideal sound you something to play with the orientation of the opening and the settings of the woofer itself. But that is a completely explained in the manual.
Design: Ideal. Fits perfectly into a spare tire wheel well.
Instructions: Easy to read and easy to understand. The installation itself is however not really explained. So you should, if you own a genius what Electrical and HIFI is not concerned, ranlassen an expert.
Installation: The Dietz 20110 cable set you are well advised when the car plays in the compact class, and you're lucky enough to have an RCA output on the radio. Otherwise, a longer power cord and speaker cable would be necessary.
A remote connection as described in the instructions is not mandatory (only if connected via high-level input to the speaker outputs on the radio) because of Axton an Auto On - switch has, of the woofer at incentive the speaker automatically when switched mode lets start a dull "wum" and veers off well again.
5 of 5 stars and a unique purchase recommendation.
