Top Car Audio Myths...

J0ne · 11-27-2008

Happy turkey day friends.

Just pondering what are the top car audio related myths. not particularly looking for explanations that bust the myth, just the general idea. I will be doing write-ups in my own words debunking each of the myths on my website.

juts a few:
Max Power
Boxes/Enclosures
Speakers/subwoofers-size, quantity, ohm, driver placement
Dimming lights
Power Wire
Rattling-(the myth is that rattling sounds cool...which it certainly does not)

thanks for your input.

Alternator whine being all electrical noise in every system.
$150 RCA's being "a strong link in the signal chain."

Bigger is Better.
DVC is going to be louder than SVC.

Anything concerning clipping...

12" subs will hit lows better but be slower than a 10".....?
Buying expensive equipment creates a good sound system.
more speakers are better
rear speakers make the sound "fuller"

Damping factor
Sealed boxes increase damping and control
High end wire of any kind

and the best one of all:

cars sound better without EQ

These actually depends on the enxlosure design and how you install your system.

Yup, they gon't, given equal parameters.

that damping factor and slew rate dont matter.

More myths to bust:

Techflex adds mad Deebeez!

Tspence73 NEVER had Violent Bass Air!

JL Audio is the end all subwoofer

The jl Audio W3 series is a GREAT series

JL Audio amps are horribly underrated (This stems from a kid trying to tell me that his 500/1 puts out 950 watts RMS @ 2 ohms)

Capacitors actually help

All 12 volt amplifiers sound the same because a watt is a watt

Sealed boxes produce better SQ than ported with the same drivers

That is all I can think of right now!

AAAAAAA · 11-27-2008

That old school is always better.
That old school is last year's product line.

Autiophile · 11-27-2008

Tuning is easy.
Fabrication is hard.
Drivers must be designed for car use.
You must adhere to manufacturer recommended uses, alignments.
THD is the end all measurement.

Isn't that what this thread is about? All the myth/debates?

That is one of the top car audio myths, isn't it?

Ever hear of the Richard Clark challenge?

quality_sound · 11-27-2008

^^^Exactly. If all amps sounded the same he wouldn't have to EQ them to have the same response before the test.

Mine is the "distortion or clipping kills speakers" crap.

ca90ss · 11-27-2008

sq amps

claiming your 6.5" "midbass" has good output crossed at 50hz

low midbass/sub crossover point required for up front bass

df and slew rate matter

I was always under the impression that clipping to an extreme extent could damage a speaker. Basically, I was told that it's a principle of the same peak power but more power over time because the peak power is held for much much longer.

....or that was the way it was explained to me.

Autiophile · 11-27-2008

Has anyone with a reasonable understanding of amplifiers ever actually said that all amps sound the same? I thought the line was always "all amps that measure the same sound the same".

Kind of like the cable argument where the general argument is "if the difference doesn't show up in RLC then it doesn't exist".

Exactly. It's not the clipping that's doing the damage. It's the extra power over time that does it, just like if you overpowered it with an unclipped signal. Either way you've exceeded the driver's thermal limits.
