I've never been huge on car audio, so the most I've done is install aftermarket head units and speakers (no amps, subs, etc.).
I bought an old, used Alpine head unit to install in my daily driver Civic. Not intending on upgrading anything else, just want to be able to play CDs and have an AUX port.
My question is...the yellow battery wire (the one that's supposed to have constant power, I assume to keep presets and whatnot?) has a small plastic box with a fuse on it and a note that it needs a constant power source and should probably be connected directly to the battery. I've never had that on a head unit I've installed before (probably because they weren't very powerful ones or weren't internally amplified).
If I'm not going to touch the rest of the system or crank the volume up high, is it really necessary to run it to the battery? Can I just chop that off and run it through the harness? Or maybe keep the fuse box but still just run it through the harness?
