As supplied by Amazon accustomed very quickly (2 days) I went to the reviews and am very zufrieden.Hätte not thought as such a Wumms rauskommt.Habe him on the High Level Input connected (plug attached) because my work no Radio RCA connectors hat.Hab the signal from the rear speakers genommen.Hab only a Notradmulde there is the somewhat out but with a MDF board I have just made the trunk again, now I miss while 5cm in height from the boot but I can verschmerzen.Das part is quickly installed, properly set to the power cable has been pulled, I did it one day in advance, before it has been delivered, it was not magic mehr.Alles in all top value for money and recommend it to anyone recommend the slightly more Bass needs with little space requirement.
