Every time I turn the head unit on, one quick loud pop comes through the speakers. It's not enough for me to go out and buy another head unit but if there's a way to diagnose and fix the problem, I'd like to know. The model is an Alpine CDE-9845 and I've had it for a little over two years. Thanks in advance.
that happened to me but it was because i had the amp hooked up to the rear speaker rca out instead of the subwoofer out. thats all that i can think of. also when i turned the volume all the way to 0 it would make a pop noise

i had the same problem but mine was my remote wire. i rerouted my wire to the fuse box and it fixed it for a while but it started doing it again a couple weeks ago.
I had a "pop" when I first installed my aftermarket head unit, because I had the control wire for my amplifiers connected directly into the wiper fuse. The amps were coming on too quickly, and picking up the transient when the head unit turned on. I solved this by running the amp control wire up to the control output on my head unit like I was supposed to. The little bit of added delay was all it needed.

this is correct, you have to create some kind of delay. on mine i came off the signal wire from the headunit, and then ran that to a relay, to power everything in the trunk(signal wire wise)
I had the same Problem with the Alpine CDA- 9885 and it actually turned out to be the rca outs on the head unit itself, i just took it back and the replaced it no charge.
mine started out as a single pop then turned into random out of sync sub pounding, so keep and ear on your subs, if they start going crazy take your head unit back
