have several questions about Bose Kit:
With me is an Alpine radio installed with adapter. In order to install a new radio (I want an MP3 USB and so on) I need an adapter because it belongs specifically to the radio or is it a universal adapter that simply switches off the power amplifier of the radio?
The next question looks after the sound a bit:
In my opinion, my Bose Sound is good to very good. However, I can also deceive myself and my rear speakers no longer do what they should or but I already have a problem with the demanding speakers. Hmm, but how do I test this before I spend 2 x 85 euros for service kits that I might not need.
I hope to hear sounds from you
