Question: I cant pull my radio out?

i cant pull my radio out?

i have a 1992 ford f150 and of the many things broken my radio is in the top 3, it can just stop on a whime and lose all presets, and even not work at all. it seams to happen when i turn other things one like wipers. ive learned that most of the time if i turn it off then bang reallyhard on top it will turn back on (im still unsure if that actually helps, it could be the same as blowing on a nintendo cartridge, you only think it helps) but anyway i have tried to remove it a few times. i was told to stick allen wrenches into its four corner holes but that didnt work. i took 2 very long pieces of metal wire and bent them into a u shape and stuck em in there. its still stuck. i really dont know what to do. im about to just start taking it out in pieces

Question: What is Dbu, Dbv and DbV? Decibels in audio?

Posted: 13 Sep 2014 10:55 PM PDT

Decibels (as you have probably learned) are ratios. dBu (unreferenced), also called dBa (absolute) or just plain dB, is dB referenced to some ad hoc standard, like the last measurement that was taken or whatever. I have not heard of the distinction between dBv and dBV - both would be dB referenced to one volt - but lower case letters usually refer to instantaneous values.

In 44 years of professional electronics and about 6 years before that tinkering I have never used any of those terms except dBv. dBm is far more common.

Question: Speaker and amp RMS watts?

What kills speakers is clipping, which in most cases is caused by under-powering the speaker, then turning the volume level way above comfortable levels, thereby introducing distortion, which people translate as being 'louder'.

Although the below videos show subwoofer, the same goes for speakers.

It's better to give the speakers a 'little' more power than the suggested rating

You should be fine with your choice. Good luck :)

Question: Car stereo noise. When I flip the headlight switch on and off the noise stops. Not sure how to fix permanently.?

Check you grounds and make sure none of your speaker wires are ran next to power wires.
