You are getting feedback noise from the alternator, normally this is not an issue because you used the stock power wires for your new install. I am thinking you routed new wires to an unprotected power source on the car. One possible solution is to install an RF filter on the power line going to your components.

SOURCE: low level noise causing sub flutter

Power wires and sound cables running close together can cause this problem. Separate them.

SOURCE: speaker Problems

What are the outputs on the back of your stereo? & how are the front speakers wired up, to one of the amps or directly to the head unit?
If you have both amps just feeding the subs & the front speakers connected to the stereo then there should be a setting somewhere that allows you to do this. Have a look on the stereo, some have a switch on the back so that you use one or both internal amp for small speakers & the output for amps.

SOURCE: My speakers do not work but my subs do.

Good day sir, hi, there reason why speakers don't work could either be the folowing:

  1. you speaker voice coil is burnt, to test, you need to get the door speakers out and locate the terminals, prepare a 1.5 double AA battery, use this to test you speaker. connect a wire from the negative of the battery to the negative of the speaker, and the positive battery to the positive terminal of the speaker with a series of gentle taps, you should hear clicking sound. if not replace the speaker.
a9b085b.gif Do it on the other door speaker.

2. check your speaker line from the amplifier to the door speaker.
3. check your power amplifier for loose and improper connection.
4. check your power amplifier itself. Thats it.

Its a little work, visit your local electronic repair shop if your speaker still won't work.

SOURCE: I have a 2005 nissan

take a look in the back of the Bose..cause most have a separate exit for the amp of the sub ...with RCI plugs ..and will not affect the normal left right exit for the regular speakers...all you need it is an amplifier for the woofer cause those exits I dont think are amplified...and it will react to the volume from the Bose ...
here you have some sound harness scheme ..just in case you do not have the extra exit for sub-woofer on the stereo...

I can hear engine humming in my car radio. It is factory.

If the speakers and subs are factory then it is likely a burnt diode in the alternator. If aftermarket AMP was added it is likely a ground isolation issue.

My 2005 accord's radio will power on, but nothing is coming out of the speakers. at one point the speakers would produce a sound and then cut off and even after having this problem was able to turn off...

If you remove the radio, you could check the speaker wires with an ohmmeter to see if any of the wires are shorted to chassis ground. If they are not, the radio is the problem.

Adding line out inputs for RCA cables to amp

Hello ssmotorcity,

Here's a link to modifiedlife's Durango page showing the wire colors.

If you are adding a LOC for an amp to drive a sub, you are probably better off using the rear speaker wires, the last four wires shown on the listing. If you are adding an amp to drive all 4 channels, then of course, you need to convert both fronts and rears. The simple method is to tap directly into the appropriate wires and connect them to the line converter. If you do not want to tap the wires, you can purchase aftermarket wiring harnesses that are made to plug directly into your vehicle radio and/or the vehicle wiring harness. The Metra part number for a stock radio harness is 71-6502. It plugs into the radio and provides pigtail connections for power and speakers. There is, of course, a harness that plugs into the vehicle harness itself, allowing you to make the connections without any cutting or tapping of the original wiring.

Hope this helps.
