Re: whistling sound


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

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 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.

I have a 2000 eclipse....i just put in one of those touch screen cd players with a 7 in it kinda sounds like **** because i think the dashboard speaker went...can i just buy door and back...

yes. You don't need the dash speakers, you can just put door and rear speakers in. Also for the front you can get component speakers and put the tweeters in the dash. Trust me, it will sound great! Make sure whoever is doing this knows what their doing because another thing that can cause your system to sound bad is phase and polarity problems.

No sound out of tweeters, highs out of woofers?

it does sound like you shorted out your crossover which can be fixed if you know what you are doing, but in the long run i would try to get another one i know that raidoshack sells some small ones and is also cheap, if your positive that you didnt short out the crossover se if it needs power, see if you can cross your woffers and tweeters on the crossover, if not is there any settings that u can change on the crossover? hope i helped :)

Pioneer GEX-FM903XM, system works great, however it often drops out and has just static. The signal indicator is strong. I think there is a bad connection into the radio. Where should I start...

It may be possible that the FM frequency chosen during setup, is in use in your area by a strong signal from a local station. Change to another frequency and see if the situation improves.

The following is from the Operation's Manual:

FM Modulator Setting
You can adjust FM Modulator frequency and output level.
7 Frequency
If output from the FM Modulator is hard to hear due to interference from a strong broadcast
station transmission, you can switch to another frequency.
You can adjust frequency between 87.9 and 90.1MHz.
7 Level
If the output sound is too quiet, too loud or distorted, you can adjust FM Modulator output
You can adjust level between “LEVEL–1” and “LEVEL–7”.
1. Press the POWER button for 2 seconds to enter the FM Modulator Setting

2. Select the desired frequency
with the left/right arrow buttons.

3. Increase or decrease the Level
with the up/down arrows (buttons).

4. To cancel the FM Modulator Setting mode, press the POWER button again
for 2 seconds.
• After entering the FM Modulator Setting mode, if you do not perform an operation within about 8 seconds, the FM Modulator Setting is automatically canceled.
