Question Seek advice for ss pn4.1000d

Today I installed the ss pn4.1000d amp to my 2013 street glide, it is all good until I started tuning it. To clarify I'm running the harley HU and a pair of JBL GTO 638 (swapping over to hertz soon), had the amp connected with the hi input side.

Here's the problem, when ever I crank the volume up higher to hear for distortion the sound stopped coming out for a sec and continue back on for a sec or two and no sound for a sec, in the same time when there is no sound I notice the protection on the amp lights up and disappear. Is there any thing I did wrong? Please advice. Hehe still a newbie here.

Check the polarity of your speakers. In other words make sure they are connected +/+ from the amp to the speaker and -/- from the amp to the speaker.

In the tuning by ear process you should start with the gains at the lowest setting then set the volume at 3/4ish. At this point u are not going to hear any music, maybe just a tad.
Now with the volume at 3/4 u introduce the gain slowly listening carefully for distortion. Once your hear the distortion u will now back off the gains just a tad. U want good clean music at 3/4 volume.
Hope this helps!!!!!

What I found with that amp and similar speakers was to set the amp on HP setting and the freq set around the half mark and the gains between 9 and 10 o clock.Your gains may be lower using the high level inputs

Edit
By the way I just noticed you are using a stock hu. I had done some testing on 13 and down HK head units using a DD1 and a 1k 0db test tone. My findings on those head units is that they show distortion at half volume and up.
So it may be hard to get a clean undistorted sound at 3/4 volume. Try setting at half volume on the head unit BUT REMEMBER NOT TO GO OVER THAT HEAD UNIT SETTING ON VOLUME after your happy with your settings or you will have a short life on your speakers.
Good luck and hopefully the info you get from the members will help.
Let us know how your tuning turned out

Thank you brothers for the advices, yes the polarities are at the correct placement. I did a triple check on the wirings before turning on, worried i might fried something if the wires are at the wrong placement.

I was trying to reach 3/4 of volume when it happened, the spot where I hit this problem is at the wording in between "M" & "E" (VOLUME) at the stock HU where i presume the 3/4 volume is at. So i backed the volume down a tad, and forward to another song and up a tad and it seems fine then but still can't maintain at that 3/4 volume for long.

So far during tuning i still have not yet heard any distortion yet. Might be the songs are at a high bit rate, but i did back down a little bit of volume to continue testing and listening. Now i'm using high inputs, so does that mean its advisable to use the RCA instead? I do have a pair of RCA purchased earlier for this project, just that I find it easier to test it out with the high input. Hahaha I am worried that I'll somewhat burn the voice coil on the speakers, since the output of that amp is high and the JBL speaker are rated at 60RMS if not mistaken.
I will try out the advices soon later and update here again soon.

I did encounter problem button up the fairing once i was done with it, I've gone thru certain thread where my placement was actual too front flush with the HU. Will try pushing the amp all the way back nearer to the speedo. After months of research and reading finally paid off, many thanks for those who had contributed and spend time researching on this amp and others. Even hitting a small snag I'm very very satisfied with this amp. Thank you for the advices

Oh yea btw, I forgot to mentioned that the amp is on FLAT, and the stock HU is also on FLAT setting too. Just wondering should i turn on the VAC or not after I'm done with tuning.

Another thing to take into consideration Ben is the RMS rating of your speakers. They are only rated at 60 RMS and unlike the 2 ohm Infinity speakers that will take much more power. The JBL's will not. What you are essentially doing is pumping 250 watts into a cheap speaker rated at 60 watts RMS. The SS 1000D is a very powerful amp at 2 ohms. Those gains need to be very very low. The crossover needs to be on HP crossed at 100-125 Hz with those speakers. Now you won't have that issue when you purchase the Hertz speakers.

Hahahaha Gannicus hats off, I too realize it after mentioned the JBL. Getting the Mille pro soon, as it in planed prior to this installation. The gain now is sitting around 10 o'clock, I'm not in for any ride soon but I would like to know is there anyway to get the fairing in more easily. I readjusted few cables to fit the amp all the way in but still during reinstalling the screw are bit hard to get in place.

Yooperhog, thank you AVC is now turned off.

Even tho not having a good pair of speaker now, just now testing out the sound and it was loud, very loud till my neighbor complaint hahahaha

Re-installing the batwing fairing is a one man job if all your wires are organized in the fairing. If they are not. It quickly becomes a two man job. Make sure the fairing has minimal pressure pushing it outward. The closer the three screws at the top are to the inner fairing the more success you will have getting it buttoned up.
