buzz or humm coming from driver side speaker when running
buzz or humm coming from driver side speaker when running Just replaced the speakers with alpine fronts and connected all four wires 2 to the mid bass and the other two to the tweeter. Just wondering what could be causing this.

Were the Alpine speakers components or coaxials? If coaxials, you can't connect the separate pairs of wires designed for components to them without modifying the speakers. If you did connect them without modifying the speaker then you're basically bridging channels on the Monsoon amp which isn't bridgeable. Turn up the volume and watch all the smoke come out of the amp. (Once you let all the smoke out of an electronic device, it won't work anymore.)

If it is a coaxial you should not connect all four wires to the speaker because the tweeter and the mid are wired together on the speaker. By doing this you basically connected two channels to a single speaker. To modify it you would need to disconnect the tweeter positive and negative from the mid driver. That can be a hairy route to go. If you are going to use the stock amp you will want to go with a set of component speakers and connect them seperately.

There is a factory tweeter and seperate mid-driver. Most people that install components to replace the factory ones use the factory mounting spots for both so no new holes need to be cut. As far as the buzz it could be a ground loop, have you changed anything other than the speakers in the system? If you reconnect the stock speakers does the buzz go away?

However, I agree with SparksAI... it sounds like a possible ground loop problem.

Since you did the head unit at the same time I would look there first. electronics are kinda funny that way. Only certain channels can pick up ground loops and others wont, it really depends on how the internals are designed. Is the buzz only when the car is on or does it matter?

Yeah you have yourself a ground loop. When you installed the head unit do you just use a harness adapter or did you ground the headunit somewhere else?
You are going to need to change the location of the ground. If you or a friend has a multimeter set it to read dc voltage and turn the car on. Holding the ground probe to the negative of your stereo, touch the positive probe to various areas and bolts under the dash. Try to find a place that has a reading of 0 volts. Ground there. If you don't have a multimeter it gets a bit harder and you might have to do a little trial and error, just groung it somewhere then turn the car on, does it make noise? yes then move the ground, no then stick and forget it. Good luck to you. Ground loops suck but I think you can fix this with little worry.
