I tried searching, but no luck. I could use some input from audio enthusiasts.

Problem:

- Humming noise coming from speakers
- Humming more noticeable when A/C on
- Humming gets higher as I accelerate
- Gone thru a couple of fuses (80 AGU)
- Speakers will cut in and out (sometimes after 40 minutes of driving or 3 hours, it's very inconsistent)

Any help appreciated.

alternator whine.

list all the equipment you have and how you have everything wired.

EDIT: after reading up on alternator whine, this seems pretty close to what I'm experiencing, so I'll check it out.

Setup:

Phoenix Gold RsD front speakers
3 JLW10s (Rockford amp on box)
Old School Rockford Punch amp

Not sure how it's wired. My cousin did it all.

Yes, alternator whine. Output of the sound matches your engine speed sort of.

no amps?

I used to have that problem.

You can either read what I sent you above.. google some more.

I added a ground loop isolator to my amp powering my speakers, not my sub.

btw nice cheap but good choice on components

Yeah I was on a budget when I did that set up. I love the PGs and the subs are good enough for the type of music I bump.

Do you have a stock head unit or aftermarket? How are the amps connected to the head unit, through the factory speaker wires or through RCA cables?

This doesn't have anything to do with fuses or anything by the way, or the speakers cutting in and out. Those are both a different issue than the speaker wire, BUT if you have something like a grounding or power issue, that could be responsible for the alternator whine.
