The bass rumst neatly in my golf 6. And thanks to the controller, you can easily and quickly adapt it to his radio sound. The perfect addition to a factory anyway well-equipped radio (RCD 510), which lacks a bass support only.

What is not specified in the product description: It is the complete harness this (power and speaker cable 4m, ground cable 50cm)

What do you still need to buy: A backup that belongs near the battery (I wonder why is not); four cable thieves and 2 eyelets.

I have connected the bass on the radio outputs of the rear speakers. An additional Hi-Low converter and an RCA cable you can save. It took me about 4 hours -alleine-. Next time I will instruct a workshop. Modern cars are built simply too complicated. A workshop had approximately 100, me - tasted.
