Hi, some days ago I installed a few car-audio components to my '04 Accord Coupe:a subwoofer, 6 speakers (i changed the standard speakers from Honda), an equalizer and an amplifier.

All of them from well-known brand names, and the audio is now amazing. The only problem is that when i turn on the car, eject a CD from the 6-cd changer, insert a CD or turn off the car I hear an annoying noise.

The guy who installed all this stuff said that there is a difference of voltage (?) between the subwoofer and the car-stereo (original from Honda). He installed a 'relay' but the noise is still there.

Do anyone has experienced this problem after installing car-audio components like these? What's the solution? Please help me.

i might wanna post you question here -> http://www.v6performance.net/forums/forumdisplay.php?s=&forumid=151. traffic there is much heavier, so you get better chance to get your question answered.

Thanks for your advice. I posted my message in that forum. Thanks again.

I also get an annoying sound when starting, but a buzzing sound originating possibly from behind the sunroof switch. It happens very rarely, but enough to cause a concern. When it buzzes, the starter doesn't engage, but if attempted again, it'll start perfectly.

One thing I notice, and this may or may not be related to this problem, but I noticed in the first ignition key position, the amp does not turn on. I think it should be on at this position, right? (Possibly bad wiring if so?)

I have an 03 accord ex with a 300 watt amp. with sub. Any help out there? Is this just simply bad wiring? Bad relay? Voltage difference? Thanks.
