Re: audio

Did you get subs? is that drownding the factory speakers out?? if so you will need to replace them with aftermarket and a 4ch amp, just running an amp to the stock speakers will cook them in seconds

I have power and everything to my head unit, but the sound isnt very loud, and everytime i switch radio stations, the speakers make a popping sound. Did i connnect something wrong?

Your system has a factory amp, you need a different harness or you need to bypass the amp. Knowing the make/model/year of the car would help.

My jvc kd-g820 will not produce any sound and not accept cd

try to find the reset a little indent on the face or hole when you remove the face and push in for 2 to 3 secs with a pen or paper clip. Then try your cd again. Still dont work check to see if you have another cd jammed inside and your trying to put two cds at once.

Ok for your no sound problem. a bad speaker, short speaker (one 1 speaker shorts out all will not work cause the radio is in a protective mode), factory amp needs to be turned on, bose system or amplified system in car needs to be rewired to bypass factory amp), buy special car harness to make factory amp compatible with aftermarket radio, late ford models the back speakers are crisscrossed.

Next time please give car info and type of system you got in it so I could narrow down the possible problems a little bit easier.

Auto decks and speakers

That's a 200W total output, which in a four-speaker system means 50W to each speaker. Keep in mind that this is a peak output, not a continuous power output. When you shop for amps or head units, pay more attention to the RMS rating (most of the better brands will give you both). This is the amount of power the unit puts out continuously. The peak power rating is how much it can put out in a burst. Similarly for speakers, buy based on the RMS rating more than the peak rating - you want to know how much power you can safely pump into the speakers continuously - the RMS rating will give that to you.

By definition, RMS value would be (peak rating) x(.707) but for ease of use, look at a peak value and figure on an RMS (continuous) rating of about half that - it allows you to err on the side of caution.

For what it's worth, 25W continuous to each speaker may not seem like much, but a lot of factory stereo systems put 15W or less to each speaker. 25W by comparison is a significant step up.

Ok . Is the sound came from the speaker? if yes then, you should put or connect ground wire from your stuff to the ground. so that all the noise will be eliminated.

may this help, fixya melnavz

Plays radio not cds

You may have Power antenna and amp remote turn on wires switched. Your system may be looking for turn on signal from radio and only gets it when am or fm is on because power antenna wire is hooked up instead of amp turn on signal.
