Car radio built-in fuse - sufficient?

post #1 of 3
Thread Starter 
Hi guys,

I bought a new car radio for my parents, installed it but have one question:

This radio has a built-in fuse. The old one didn't, so there had been a fuse installed in the power wire, which I have removed, to save some space.

Have I made a mistake?


And another thing:

I connected the black (negative ground) wire of the radio to the truck's ground wire (with the ISO connector), rather than the chassis directly. It works fine. But there's also a so-called 'rear ground terminal' on the back on the stereo. Should I attach a short wire to this and connect it to the chassis? Would this 'double' grounding make any sense?


Thanks for any replies.
