I like working with a scope too, so I'll set the Batteryminder up so it's running around 13.8v, and then I'm able to take my time with the tuning. I find that my bike hovers around 14.0v running so that's pretty close.

I'd agree that 34.6v is probably a little hot out of the box with no DSP. I set mine for ~33.1v which is around 275w. I'll tweak it more later when I get the DSP.

But again, I never bring it up anywhere near 3/4 and mostly run at or below 1/2. The few times I brought it one notch over 1/2 and it gets damn loud. Sounds great but these old ears can't take it that loud for long!

 

If y'all get lithium batteries u don't need to run the sled to set the gains!!! This shix really does never end.

No sh*t. It doesn't ! I really don't need to be dropping anymore coin like I have been lately. Its gotta stop man, and this forum isn't doing me any favors, Im supposed to be saving my money for my 66 Chevelle ss, that I don't have YET.

So no more post like that lol

 

[QUOTE=SBates08;20002249]And move the switch to HPF. I'd start it at 100hz without using a dsp and ease my way down from there. You may make it to 80hz anyway but there's a chance you may not.[/QUOT

I used the 1000Hz is that the right test tone to use or should I be using one of the below?

1-100Hz: 0dB Download | -2.5dB Download | -5dB Download | -7.5dB Download | -10dB Download

90-100Hz: 0dB Download | -2.5dB Download | -5dB Download | -7.5dB Download | -10dB Download

 

[quote=rsking45]Use the 1000hz test tone for setting gains. My post was referring to the crossover on the amp. Move the slider to HPF and set freq dial to 100hz and work your way down to 80hz. Always, I repeat always start high on the crossover frequency and work your way down.

 

[QUOTE=SBates08;20002806]Just making sure, I'll take the probs of the dmm in a channel 1 . Positive to positive , negative to negitive. I switch hpf , play the 100hz tone.hz Where should the volume be set at?
I watch the dmm and slowly turn the dial down untill the volts start to fall off. At that point I should be at 80hz.
Which do I do first. Set amp gain or the crossover?
I watched a few videos on YouTube, so that shows ya I don't know what the f:'k I'm doing. I'm learning along the way

 

Umm no. First off are you bridging this amp or not?

 

Yes sir I am

 

Set everything to flat (bass, treble, cross overs speakers in the middle,etc) gains down. Set the HU volume to 3/4, If bridging, red lead on positive channel 1 and black lead on negative channel 2, etc. . Turn the gains up until you reach your target, repeat for the second set. Set the amp to HPF when gains are set......as mentioned, start at 100 and work down as needed. There is also a sticky that explains

 

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.
