Yes, but it can be hard on them if they are cold and not warmed up.
If you can't figure that out have you subs installed by someone who knows what their doing.
Depends on what your willing to spend.. For two 1200 watt subs I would go with a 1200 watt amp and run both of then 600 watts ( you don't want to always run subs to full power, because the voice coil might blow or you will light your subs on fire). If your feeling brave you can run a 2000 watt amp 0_o that will annoy your neighbours, but make your car bump!
Antifreeze/Coolant is a fluid that prevents the car from overheating or becoming so cold that it won't start. Without it, in the summer, your car would run too hot, and in the winter, your car wouldn't run at all.
No.
Do you have the defrost on? My 91 does the same thing.
Car dealers run credit multiple times during the car buying process to check for the best financing options and to ensure the buyer's ability to make payments on the loan.
The dealership ran my credit once during the car buying process.
low pass is for subs only it tells the amp to play low frequency only dont run subs on high pass or off
To prevent your outdoor water spigot from freezing during winter, you can insulate it with a cover or wrap, disconnect and drain hoses, and let a slow drip of water run during freezing temperatures.
A dealership can run your credit multiple times during the car buying process, but typically within a short period of time to minimize the impact on your credit score.
Typically the exhaust ports on diesel subs is below the water line. This helps prevent smoke giving away the sub's position. While underwater, they run on batteries and have no exhaust. Nuclear subs run on steam and don't have exhaust either.
low temperatures can increase viscosity of fuel and/or lubricants, and it can sometimes drain batteries, etc.
