Hi

the problem you are having is most likely electrical noise generated by your alternator one way of fixing this is to get a noise filter or noise suppressor other wise make sure your power cable don't run adjacent other wires this itself might create interference this includes your aerial wire

How do I go from "Protect: mode back to FM play on


The word protect will engage when you have output problem and will shut the audio off so no sound is available, however if the sound is working normally with protect visible then there is clearly processor issue, something I have never seen before. But it should be checked by a qualified tech.

Hello again. Sorry to say my knowledge is lil... I want to replace stock deck. Here is the stuff i want to put in it. Could you take a look and give an opinion if maybe i cant get away without putting a...


ok as for the deck just get the wiring harness for your car so you dont have to cut the old one out and that would eliminate the need for a wireing diagram with that done you should be able to hook all speakers you want to the stock spot so for a tweeter just hook it up with the door speaker there arnt any extra cords....you will only need a amp for a subwoofer unless you choose to put your mids and highs on one and if you didnt want to change your deck hook up the tweeters would be the same way hope this helped

I have a problem with my car speaker/tweeter


Sounds like you have the ground and live possibly the other way around from the head unit to the speakers. The reason for you hearing it from both the tweeter and the speaker is that the tweeter is connected in parallel to the speaker.
Swap the wiring and try it.

RCA rs2600 every thing works but the radio.When the source is switched to AM or FM no sound comes from the speakers.The sound works fine with the CD or tape.


Try to clean the selector mode switch with a contact cleaner like "electra"that safe to all surface plastic or metal.If still the AM and FM not working.You better replace the selector with identical rating parts.

Hope it may helps;
