****** ass equipment!!!

Dude, paragraphs...

Could be the power supply, but I'm no expert.

 

Please explain how you had the speakers wired in series....I'm curious about this

 

Eliminate variables. Plug the LH into the GK and go from there. That combination should get plenty loud for most gigs.

It sounds to me like you were simply asking too much from your rig (no PA support, distorted tone, etc.). If you find the problem recurring, you should either get a second GK Neo 410, or get your signal into the PA via a DI or a mic.

 

Yes, you do need help. Spacing and paragraphs would help immensely.

The "pink noise" you speak off sounds like your picking up outside hums, like fluorescent lighting, can be addressed by giving your bass a proper shielding job, if it is a Fender it has never had that done. Also, try using just a cable into the amp, wireless systems, especially cheap ones, are really bad for sucking out tone and adding in unwanted noise.

If your speakers are distorting, you are blowing them, turn it down and/or adjust your EQ.

 

I am not being a smart a$$ but, what is pink/white noise?

 

daisy chaining cabs like that it still running them in parallel. (i.e. it will halve the value of the two cab's impedance).

 

I think we have the answer...

 

Thanks for the reformat Doc. I wasn't going to read the OP.

Possibly a bad cable.

When you say connected in series you're talking about the preamp etc, not speakers?

 

Yes thank you for reformatting! If your speakers are complaining then it does not matter where the "volume" is on the amp. You have enough signal strength to over-power your cabs. You may have already damaged them, either the amp is seeing an overload or the speakers are overheating and soon won't come back. You need to be in the FOH.
I suspect the 115 is the worst off.

 

Cab ratings can be misleading. More often than not, they cannot handle what they're rated for, due to the frequencies your bass is capable of. (lower you go, more power you eat). Lose the 15, get another matching 410, and watch the eq.

 

Also bear in mind that the 115 cab will only handle about 1/2 the volume of the 410, another 410 will help get loud-clean.
If you have to use both 410 & 115, put the 115 on top-then you'll hear it complaining before it blows (if it already hasn't).

 

Sounds like you may have a problem with the head, or your speaker cabs/cables.

BTW:

Seems counterproductive. Doesn't the "Enhance" knob cut the mids you're boosting elsewhere?

 

In case you might find it interesting and not unduly boring . . . white noise is sound with constantly varying levels of all the frequencies, that has, on average, equal levels of every frequency. So as much 40 Hz as 1000 Hz. Pink noise is like white noise except it has equal power in each octave, so as much 40 - 80 Hz as 1000-2000 Hz. In other words, less and less power as you go up in frequency. AFAIK, pink noise was developed to more closely mimic the frequency spectrum power of real music, etc.

In my day the dinosaurs and I called it all white noise, but they've become extinct and I've learned a little since them . . .

 

Lose the BBE for starters...and the wireless is suspect. It sounds to me like you're really overloading the front end of that amp, so even if your knobs are not extreme, the signal you're giving it is.

 

You can always start without all the "effects" and straight with a cable to the amp. Add one component at a time to find the noise maker.
