Put the DMM back on the shelf for a while. Hook up all ur speakers via the bridged wiring guidance for ur amp.
Select HPF on amp. Turb gains/sens all the way to the left. Set the freqs at about 90. Turn sled acc on w battery tender/charger attached. Play ur favorite song from u favorite genre. With gains all the way down still, turn ur HU volume up to 3/4. Now adjust gains up / to the right until u get pretty damn loud but the speakers have zero distortion. The most noticeable distortion will be the lower freqs / bass. U can set the freqs lower to 80 is there is absolutely zero distortion present.
Go ride.
After u get familiar w how volts/watts and freq work closely together for max performance u can go back w the DMM and set optimum volts w DMM then use ur keen new ears to adjust the freqs to allow as much of the lower freqs thru the filter without distortion.
Typically the lower freqs blow up 6.5s w too many watts.
Thus what u are doing w the HPF setting and freq **** is telling the amp filter what freqs ur gonna allow thru to ur speaker.
HPF let's what u set and the higher freqs thru to ur speakers. IE 99-20000hz
LPF is selected will only alow what u selected and lower freqs to ur speakers. 90 to 0 hz. Typically only used for subs.
All/Full let's all the freqs thru to ur speakers. We generally don't use All/Full on a sled simply because we are chasing higher volumes in exchange for a little less bass ie 80 or 90 or 100 hz and above.
Ur speakers will indeed play some freqs at 50hz and above but they will distort before u get the volume u desire at 70 mph.
U picking up what I'm laying down?
Ditch the DMM and play conservatively until u understand how all this ties together. Then u can seek the ragged edge of the performance capabilities w a DMM next weekend or after u break the speakers in and understand how far u want to take the speakers regarding the balance between volume and bass.
Cave Man shix can indeed work as long as u slowly work into ur setup w a keen ear.

it can be daunting at first. Once you get the basics like t said, then you can start really tweaking things a little more in depth. I'm still very new myself but some great guys here are willing to help all they can for us newbies.

Now it's really bugging the s'*t outta me.
A few years ago when I installed the b52 and kappas,I always had noise, sorta like back in the day when a tv station went off the air for the night, white noise I guess . No matter what, the noise was there. Isn't loud , but if I put my ear to the speaker, I hear it. Even with the gain all the way down, the noise was there. Never did figure it out. Then the kappas came out and mmats went in, noise was there.
Now that iv upgraded to more expensive stuff, it's still there . I'd really like to find out what is causing this. It's something with the wiring. Power and ground ,8 gauge is at the battery with a fuse block close to the battery. I ran new speaker wire and made sure that the speaker wires are away from the positive and negative cables.
whatta all think, what can I do to eliminate the noise?

Does this noise increase in volume as you increase gains? Can you hear the noise while playing music at any volume? Is the noise there if the motor is running or not? What about when riding? Can you hear it over road and wind noise?
If it's noticeable at volume and gets in the way of enjoying your system or ride then it's worth resolving. If you can only hear it when the motor is off and the volume turned down, no music playing, and with your ear to the speaker, it's not.
I used to be a serious audiophile and spent huge money on my home system. Components, source material, power, sound damping, etc, etc, etc. No matter how much time, effort, and money was spent there was always something that could be improved. To say a bike is not an ideal audio environment and not comparable to a high-end home audio system would be an understatement.
I'm not saying there isn't something that could be done to improve your noise issue but you have to ask yourself those questions first to determine if it's worth the effort or if you should just go for a ride and crank it up.

As far as noise goes, it just may be as simple as the rca cables. I would try replacing them first one at a time to see if that eliminates the noise. I have had it happen before. You can also try using this as it may help also.

IT isn't effecting the music at all. I don't hear it when music is playing. The only time I hear it is when I turn the ignition on. Once the bike is running ,I don't hear it. I can turn the gains all the way down and it sounds the same. I don't believe it's hurting anything, I never blew a speaker or a amp.

Are they run right next to an LED headlight? In contact with it?

The noise is very faint and can't be heard with the engine running or music playing. IMO it sounds like inherant floor noise and isn't worth the effort to chase down. But it is your ride and if it's driving you crazy... (I'm a little OCD so I could completely understand)
