Is it safe if i leave my subwoofer in my car during winter?

Is it relevant to take out my subwoofer enclosure from my car's trunk?

Don't worry too much about your subs because yes its safe to leave your subwoofer in your car, during winter. Just take make sure you don't damage your car subwoofers in cold weather, its always best to warm them up for the first few minutes. To warm up your car subwoofer, simply play music at a low volume level for about 3 minutes, once the 3 minutes are up, your car subs are completely SAFE!
