I’ve never been a huge car audio guy, but I’ve always wired up my basic radios.
I’ve never used a separate amp, though.
I’m installing the Blaupunkt Bremen SQR 46 DAB, along with a small Alpine KTP 445U amp.
My car also has a powered antenna that goes up and down when the radio is turned on.
I think I have the powering circuit correct, but can any experts confirm?
Here’s the Alpine amp instructions
And here’s how I think it should be wired. (The numbers correspond to the numbers on the Alpine amp instructions).
Note that my head unit only has one blue output trigger wire (it’s marked “power antenna”).
I plan on attaching both trigger wires for the powered sub and the Alpine amp to that wire, as shown on the diagram below
Seem ok?
(One other question, couldn’t I have the blue antenna trigger wire wired directly to the antenna, Alpine amp and powered sub? All three of those trigger wires attached to the head unit antenna trigger wire)
