Sub half as loud in cold weather?

[Notloud00 10+ year member]

x2, colder air always = louder for me.

i gained .4 db and lowered my peak 1 hz goin from 100 degree to about 50 degree weather. pretty awesome

im just pulling this out of my ass, but if you think about it, it makes sense. in cold weather, the soundwaves have a harder time traveling through the air because it is so cold and dense, but when the air is hot and hardly dense at all. i bet if there was a way to super cool voice coils and amps, you'd get ridiculous numbers given the equipment...

depends on what kind of cooler air, like 40's - 50's or sub zero - teens? also would depend on the sub as mentioned.

I did the volt test again using Kanye West 808's and heartbreak went from 14.04 to 13.88 volts //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif still dimming though //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

bass still low in power

If you're getting dimming on only 500 watts even in the summer something is wrong, I'm thinking your battery must **** ass.

idk why cold and dense air is easier to pressurize tho meh idk why the peak goes down either, mite have to do with the car idk.

is your amp a class a/b?

my sub amp is a/b and is 600w and bridged. so when the bass note is punchy it causes my lights to dim a little. when it hits long notes it doesnt. just an a/b characteristic.

 

[microhaxo 10+ year member]

Well when i have LONG rolling bass the dim is very subtle, on the tight hits it is dramatic like you said.

I almost dont even want to drive down against traffic when i am playing songs like that because i think my lights look all messed up and blinking..

says for specs:

Class: A/B

 

[oldschool4me 10+ year member]

its the amp, if it bothers you then your going to have to go to a class d amp.

 

[oldschool4me 10+ year member]

adding a battery may help also.

:| well can you guys recommend a quality amp under ~150.00 that will do 500-600 watts rms clean at 4 ohm or even higher?\

Edit: i found this and it matches the brand of my sub:

http://cgi.ebay.com/PHOENIX-GOLD-V8001-1600W-Class-D-MONO-RYVAL-AMPLIFIER_W0QQitemZ360109065636QQcmdZViewItemQQptZCar_Amplifiers?hash=item360109065636&_trksid=p3286.c0.m14&_trkparms=72%3A1234|66%3A2|65%3A12|39%3A1|240%3A1318

is it a good amp?

at 4 ohms will be hard to get a good class d and get 500-600w.

if that is all you have i would go with adding a battery or selling the amp you have and put that with the 150 or trade with someone and add cash.

It seems like my voltage is better now that it got cold.
