As discussed in another thread, I would like to know what some of the common misconceptions are in car audio. I'll start with my biggest pet peeve...
Damping factor on an amplifier DOES NOT equate to better cone control, tighter bass, or better sound quality (Ess que) contrary to what many have heard. Also, the higher the number doesn't always necessarily mean the "better" an amplifier is, especially in the 12 volt world. damping factor in the car audio world was a spec contrived by someone's marketing department and continued on through the decades with the bigger number meaning the better the amp.
I am trying to find the clinical trials that blew this myth, and I am having a hard time locating it. Regardless, if the damping factor is greater than 50, chances are one will NEVER hear the difference.
ETA: I forgot the biggest boo boo. In the past, some of the amplifiers with the highest damping factors used to cheat. They rated them at the circuit board instead of the speaker leads or terminals just so they could post a bigger number.
I have more misconceptions, but I want the collective to chime in on things such as slew rate, stiffening capacitors, THD, etc.

Can't recall where I heard that, but it seems to me that where amplifier dampening factors are concerned anything over 50 is supposed to be adequate and higher slew rates are favorable.
I choose an amp based on power output, physical size and cost. Beyond that, I rely on reviews of real world experience to judge performance potential until I can hear it for myself. The rest of the specs have come to mean virtually nothing to me over the years.

ahhh... but which stock alternator, and what is the guage wiring used in said vehicle for ground and hot?

How about a certain brand that advertises 50x4 OR 325x2 all on 25 amps of fusing. 200 watts RMS I can almost believe with that fuse level but there is NO WAY I believe 650 watts RMS on 25 amps of fusing.
If you can find one of those amps, they still go for $700 to $750 which I find even more shocking...

Is it possible for us to make this thread one with a stated myth and then proof to back it up? That way it's possible to weed out the people who think something.

Like a snopes for car audio?

"Putting subs in front of the car will ensure the bass is coming from the front"
I don't know if this is a myth or what, but last year at finals, I sat in several cars with subs in the dash, center console or even kick panels and in a couple of those (cars and people will remain nameless) me and several others noticed the bass seemed to be coming from the rear or hard to locate. I believe you need to properly blend and eq no matter where they are physically located. I heard others where the subs were in the trunk and seemed as they were out on the hood!
That people don't realize that power is 10 base logarithmic to SPL.
