If the radio in a 94 Dodge Spirit goes out but the dome light still works is it just because the radio is broken or could it be an electrical problem?

The circuits have nothing in common. The dome light works whether or not the key is on, the radio only works with the key on.


When radio is turned on electrical current flows through it what main type of energy is produced by the radio?

The electric power supplied to a radio is used to produce two types of energy: heat and sound. The sound is the useful part, and work is always continuing to find ways of producing less heat, because it only uses up electric power, and there are much better ways to keep our hands warm.

How do you get your infinity sound system to work after installing a new radio in a 96' town and country?

Did it work before you replace the radio? Is the radio an original equipment radio? If it is original equipment, the radio wasn't the problem, the sound processor under the dash was. If it's an after market radio, you need to bypass the Infinity sound processor or make sure you have a wire connected to remotely turn on the sound processor. If none of this is the problem, check the fuses. In most cases, Chrysler recommends not running your after market radio through the Infinity premium sound system as does G.M. and Ford. You over load the processor and not only that but the ohm rating for your speakers doesn't match. Hope this helps

What is the difference between HD radio and satellite radio?

Once you buy an HD receiver then you will get HD radio for free but your stations have to have the feature to get the quality. You pay for Satellite Radio but you get a ton more stations and can pick and choose to listen to any within your package. HD is only for regular local radio stations that have an HD antenna. Both boast great sound quality which is true� they are way better that a normal radio station but still short of CD quality. If better sound if what you want then buy an HD receiver� if better sound and more options is what you want then buy a subscription to satellite radio.
