my dad just got his new indash put in his truck.(pioneer AVH-P7480DVD)

he asked me to send him the project i was working on right now so he could burn a dvd...
omg the sound... keep in mind everything in his truck is top of the line...
everything sounded so much better... i'm talking bout, commercial cd's didn't touch my tracks and they weren't even fully mixed...the sound was so clear.i didn't think it would make that much of a difference but it did. after i took the dvd out and put a cd in.. major difference..even in volume.. i couldn't even tern the system half way up with the dvd with the cd(ja rule) i had it over half way up, and i'm talking about a 5000-6000wRMS stereo system.

i can't wait til 24/96 is standard.. music is gonna sound so much better.
 
I would think in 99% of vehicles today road noise, poor acoustics, and mediocre speakers would nullify any advantage 24/96 car stereos would provide.
 
5000 Watts of amplifier?

A 300 watt amp would fry most eardrums. And that too would nullify any advantage of "hi-rez" digital source material. Your dad lets you smoke dope in his truck?

I'd disagree with that. You can never have too much power. It's how you use it that matters. Having more power than you need is the key to crystal clear reproduction. If there are subs in the truck they will eat a lot of power also.

So that deck will play 24/96 wav files?
 
>Having more power than you need is the key to crystal clear reproduction

Only to an extent. Any decent power amp has a band of power output where the distortion is minimal. Although I have seen PC speakers on sale for $10/ pair with a built in 400W amp.... :D

I've seen show trucks set up by car stereo manufacturers that have a ridiculous number of speakers with a separate amp for each pair and for each sub cabinet and the total wattage was nowhere near 5000 watts. (I believe it was a conservatively rated 1200 :) )

Just as in home stereo reproduction, simply adding more watts and more drivers does NOT translate to higher fidelity.

And this is a small enclosed space, not a stadium.

those aren't true 400 watt amps... more like 400watts if a bolt of lightning hits it..

24/96 wav file... i guess. thats how i sent him the mixdown...i have to find out how he burned it, he has a stand alown dvd-r and a pioneer dvd-rw on his pc

as for the power... its not enough ;) the 2 subwoofer amps put out 2200rms@2ohms, so thats 4400rms right there going to 2 Digital design 9515 subwoofers.. which are basically the best subwoofers made.. great Sq with SPL out this world.. his truck usually meters at 156.4DB when we go to stereo competitions.the subs want more power...

all the amps are Zapco and speakers are Focal utopias.

drstawl, no my dad doesn't let me SMOKE dope in his truck, i don't smoke nither does he...

TexRoadkill, you can have to much power.. i know someone is working on 1 of the worlds loudest stereo systems and they have 16 viper 2500.1's so thats 40,000RMS and just about 80,000 peak power... 4 amps each sub..Quad voice coil subwoofers... tell me you can never have too much power now;)

I think that depends a lot on how efficient the speakers are. Some speakers, Magnaplanars for instance, require considerable power to get them going. However, 300 watts through Klipsch speakers would probably be painfully loud.
 
>156.4DB

Exposure to more than even 90dB for extended periods of time will cause permanent hearing damage. I guess that's why you need more power.... :rolleyes:

my moms factoy stereo system in her car does like 120db.. 90db and permanent hearing damage.. that doesn't seem right... i'ma have to ask my ppl over at www.Termpro.com
80% of the ppl over there have systems that do 150db +.. 169db with 1 10!! yes 10inch subwoofer.. its a world record.
i think the world record overall is somewhere around 176db right now..of course they aren't in their car/trucks when they burp them that high.. you heart will pop:D 156.4 at 39hz HURTS

aren't nasa rockets somewhere around 190db??
 
Well your posts show quite clearly that you aren't after high fidelity- just more SPL. You certainly don't need 24/96 just to get more SPL. And you have little knowledge of, or respect for the permanent damage you are inflicting on yourself. Oh well. Whatever floats your boat!

And just for the record- I like some good thump in a car stereo, but have no need to drive it until my ears bleed.
 
hey i only made 1 persons ears bleed ;) but that was with 2 shocker xtreamII 15's with about 12000watts on each one:) he shouldn't have sat in the car while i was testing it...
isn't she fine, she's 88pounds too(not the one i tested just a pic of the same sub)

i know 24/96 isn't really gonna boost my scores.. it just sounds so good.. the speakers are just about as good as a lot of monitors out.. maybe better.. i can push a button and tern the subwoofers off and the quality of my 24/96 mix vs a commercial cd.. its just better. the hi's are so crisp,mids are just about perfect, and the lows.. clean responce down to about 26hz.
DD's aren't pure spl subwoofers, they offer better Sq than any subwoofer out and handle just about anything you throw to them. i'm not sure how many there are now, but at one time DD's were used in a lot of studios.

i'm gonna put a movie in the truck later on tomorrow night when i go out and see how blade 2 or something like that sounds..

and trust me driving down the street around 150db your ears aren't gonna bleed..i do it all the time... once you get to 152-153db you vision goes a little blury.. but i've only once ever had my ears even ring.. and that was in one of the last systems i did(8-12's ported in a wall with about 1000watts on each one)
 
Holy shit. I saw that magnet!!

I've also got a (somewhat smaller) chunk of magnet on two 12" full range Altec-Lansing Instrument Speakers in my guitar amp. I've driven them to obnoxiously loud with just a 2500mW Walkman.

Man- let me clue you in. You need to incorporate the magnet from a respectable NMR spectrometer into your next design. Those suckers will rip a steel wristwatch off of your arm from 6 feet!

:D

last time I checked you don't plug the amp directly into your eardrum... now I haven't bought a new amp in awhile, so maybe things have changed, but the last time I did buy one, we had not yet reached the bio-tech amp age where we just plug it into our eardrum for a full reproduction of the sound.

hmmm... its commonly accepted that permanent damage to hearing starts at around 130dB-SPL (common rock concert) but mostly occurs at 150 or greater...

90dB is equivelant to the noise of heavy truck traffic or a baby crying... if this produced permanent hearing loss, wouldn't we all be almost deaf by now?
 
150 db in a car?

'makes me wanna break out the Hummingbird and go sit in the swing on the porch..
 
>last time I checked you don't plug the amp directly into your eardrum

Last I checked most conventional speakers that could handle 300 watts would provide Ear Bleeding SPLs in an enclosed space like a truck.

My Event 20/20s get painfully loud with just 1/3 the wattage they are rated to withstand. Those Altecs that I uploaded the pictures of can be heard for miles when powered by a 100W amp. And they are rated to withstand 150W each AT 8 ohms.

>hmmm... its commonly accepted that permanent damage to hearing starts at around 130dB-SPL

You're referring to a transient. I'm referring to continuous exposure.

<rocket engines are around 180dB-SPL

Jet engines on commercial aircraft are considerably quieter than that. Have you ever seen a worker at a commercial airport out on a taxi-path without hearing protection? What do they know that you are willing to ignore?
 
I'm with everybody else. I too have a broken Audiovox tape deck in my truck and therefore I think your dad's stereo is totally gay. Don't make me go scientific on your ass!

I didn't say jet engine did I??? No... I didn't... there is a big difference between the word rocket and jet...
 
Recommended maximum allowable exposure times (by Nova Scotia Department of Labour) are:

16 hours for 80 dBA sound
8 hours for 85 dBA sound
4 hours for 90 dBA sound
2 hours for 95 dBA sound
1 hour for 100 dBA sound
30 min for 105 dBA sound
15 min for 110 dBA sound
7.5 min for 115 dBA sound
0 min for above 115 dBA sound
