I'm buying a car stereo and the installation cost is 99.00 Not including hardware I can't get a answer from them the cost on hardware.am I supposed give them a blank check?

Depends on the deck your buying!! They should be able to tell you the total as long you know the deck model you buy.

It would depend on the vehicle. The amount should always be figured before installation.

If you want to give anyone a blank check, send it my way... they should be able to tell you a total amount upon inspection of your vehicle..

Just walk away. They suck.
