It was actually harder to find the right adapter from the dealer here in town than it was to hook this one up. It went together very easily and quickly and works flawlessly. I am quite pleased.

piece of cake... works great with my Bose system... only gripe would be level matching being separate for left and right channel.. some would call it a bonus. i would call it a pain... this is why stereo manufacturers include a balance feature in the head unit

Customer Testimonial

I want to let you know that I had a great buying experience with your company. The representative I spoke to was very professional and reassuring. I received the item and had it installed. The kit worked just as I was told over the phone. The product performed as expected and I am extremely happy.
