Cold weather and subs q.

[tensionrev]

First time post. I did a search and did not come up with anything, so I thought I would ask.

What effect, if any, does the cold weather have on subs, or any speakers for that matter? I have two Polk GXR12s in sealed boxes in the trunk, and Polk EX368s all around in my '99 Mustang. On cold mornings, like today (25 degrees F this morning in the Detroit-area) is it bad to jam your speakers right off the bat, or should they warm up a bit. I have a 25 minute drive to work, so usually I listen to the morning radio talk show for about 15 minutes, then jam the last 10 minutes.

I understand that, obviously, there is some cold weather shrinking of basically any material, and it expands as it warms up. I know these speakers are not made of plastic, per se, but we all know plastic can get brittle in the cold. Is this a concern for the speakers, or is it not necessary to warm them up? Thanks for your time.

let them warm up or you could be lookin for new speakers.i let mine warm up for about 5 to 7 min and i got a 1993 cuttlass 4 inch kenwoods in front polk momo 6/9s in back and 2 polk gnx 104 in a sealed box.

well cold cold cold drops the impedance of a speaker.

for example, if you've got a 4 ohm sub, and you're at spl competition, and you want to squeak some more power out of your amp without changing the subs, you can pack some ice in your sub and chill it as best you can... the result is like a 10 - 20% drop in impedance.

as far as cold weather driving with audio -- i remote start the truck for about 10 minutes, let it get to a nice 50 or so degrees inside, and then run the radio "low power" for like 5 minutes and then i hammer on it hard as usual. the natural heat produced by a speaker's operation will help the process.

the only thing cold weather can do is stiffen the cones/surrounds/spider's up, and if you hammer on them too hard right away it's not going to help them any.

facing 10 and 15 degree days, i like to be a little careful.

better safe than sorry.
