Re: road noise

Sounds like your ground is to long (shorter the beter) or positive lead is to close to the speaker wires/other cable (try to take different paths for each cable reduces interferance)

Rockford Fosgate Power 1000 amplifier. (25 to life) When I turn it on there is almost no sound coming from speakers. I have to turn up the volume almost to max to hear something. But only very high...

turn or flip the LPF and sub sonic buttons to see if they will help.
there are other buttons called gain that you may have to turn to bring up the volume.
its very likely your eq buttons that you have to mess with to get it right. post up pics if you can.

Engine noise coming through one channel

This sounds like alternator whine. Do you have the power and ground connected to your battery, or through the accessory power? Make sure the power and ground wires are sufficient size, and connected to your battery, and make sure you have the power wire fused no more than a foot or two from the battery. If it is only on the right channely, maybe this wire is getting feedback from another wire. Seperate the wires if this is the case.

Wires create magnetic fields, and if a speaker wire is next to a power wire or something, you will hear a noise, typically high pitched whining.

High pitched squeal from Bose car stereo

Have you or your dealer tried an inline noise reducer? It worked on my truck. Worth a shot. Good luck!

I have 2004 nissan maxima making engine noise when starting n while driving?? what to do? i have 79,000 miles on the engine.

Buy a ground loop isolator and hook it up in line on the rcas, that will get rid of the whine. If you ran your power wire next to the rcas it will be louder because it creates a magnetic field. If you have a 4 channel amp you will need 2.

Your stereo is picking up alternator whine. If you're good, you can make the motor fit with the song... kidding.

RCA Whine, Newly Installed Amp

The shield ground is probably open in the head unit. You can check the shield ground by measuring the resistance from the shield of the RCA connector to the chassis of the head unit. It should be near 0 ohms. Disconnect all RCA cables from the head unit before testing.

If you find that the shield ground is indeed open, the following link has more information for a temporary fix.
