Talk about convenient.
Crutchfield Customer Review (What's this?)
Works as advertised. Mounted it to a blank plate on the black plastic portion of the dashboard, and it it looks factory. I run a 10 inch sub pushed by a 700 watt JL amp. This knob is perfect for quick adjustment when you go from one song with little bass to one that will rattle your teeth. No more fumbling through the menu to adjust the bass. Very happy with this purchase.
Pros: Extremely easy install.
