my friend works at best buy,and he's the only one that actually knows about car audio,most of the sales are because of him. He doesnt just same something stupid he will explain why this one is better or why this one is better. he gives truthful facts. but i never buy anything from best buy except acceroies,using a discount of his.

Did you know there is an 1800% markup on wiring harnesses. $1.89= with discount without it, its $18.89.

What an idiot. I believe 10dBs is twice as loud if I'm not mistaken

3db's is twice as loud

no...

10dB is twice as loud

the man is correct in that saying 120dB will make your ears bleed or make you deaf, but he is also incorrect in another sense.

your hearing sensitivity is based upon the dB(A) scale NOT the dB scale, at 1-5khz 120dB WILL make you deaf but at lower frequencies (sub-bass to infrasonic) you are much less sensitive.

To achieve the same destruction of your ear drum at 40hz you will need an additional 34.6dB (154.6dB) on top of that 120dB at 1khz. At 20hz its an additional 50.5dB (170.5dB). At 10hz its an additional 70.4dB (190.4dB!!!).

the amount of energy is doubled for each additional dB, so 110dB requires twice as much energy as 109dB but our ears cannot perceive the difference.

?????!??????!???!??? $1.89 x 18 (1800%)= 34.02

my fault bro,but still 1.89 compared to 18.89 thats pure robbery

Yup, that's exactly what I payed for mine yesterday at CC and a doller more the HU mounting kit (it wasn't my money, it's the guy's who I'm doing the intall for).

I was also at CC. When I was there I saw a really, really nice 70's cadillac deville. I cringed a little hoping they don't fvck it up.

a guy at CC told me Time Correction raises the music so it sounds higher up

Manville Smith from JL said 10dbs = twice as loud

its based on asking people to turn up the music to what they believed sounded twice as loud

theres no other way to do it really

10dbs was the average

Interesting.

I wonder what music they were playing....

You've obviously never learned how logarithms work. They are in sets of 10. One decibel increase is twice as loud. And you wouldn't be able to hear the 20hz tone or 10hz tone, so besides rattling the shit out of your inner ear, I don't understand how that could possibly cause SPECIFICALLY hearing loss.

What the **** people.

That's a logarithmic graph. Each decibel increase is twice the previous one. To the EAR, 10dB is 2x as loud, but it is actually 10x as loud. Doubling the acoustic power will give you 3dB increase and doubling the radiating area will do the same.

its not that hard to run a power wire lol.... if u get paid for it u should take your time and do it right.... i dont see any best buy or CC doing anything mroe than the basic stuff

Then you don't get out much.

That 300M that is dominating the show circuit this year, with the linear doors that flip upside down, was built at a Tweeter location in Atlanta, IIRC.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

But then again, with a pair of Focal woofers... Audison amplifiers, and 4 focal midwoofers in the door enclosure... it SHOULD be winning. Focal Be components throughout.

Here's a quick pic of the door/Doors -

That's not entirely true. The limits of human hearing as 20-20000 is only applicable at a given decibel range. Basically if you increase the volume loud enough, you'll hear well below 20hz. Granted everyday noises never get that loud, which is why we have the 20-20000 cap. However if you generate 140db's at 15hz, it would undoubtedly be audible.

Yes ... Approximately 3.5 minutes @ 120 dBA will cause permanent hearing damage ...

who needs hearing any way.. you'd feel a couple 12's pounding behind yah still //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
