I'm not sure how you can do this other than flash it back to stock (0 amp 4 speaker)

I suspect the flashes decrease the bass boost as you add Boom amps and flash ie stock with 0 amps is about a 26db bass boost, the Fosgate flash for 1 amp is significantly less as the 1 Boom amp is filling the gap, and the Soundzcustomz flash of 2 amps get it as flat as possible.

Like I said, I tested yesterday and now my HU distorts at a higher volume with the 40Hz tone that it does with a 1kHz tone. I'd say that pretty much tells the story of the Boom amps and flashes.

In theory yes but if you have a flat signal going into the BT355,the capacitor in the BT355 is knocking it down the bass boost by about 26db.

Something else I just thought of, do you have the ability to use the bass and treble ie it goes up and down (NOT the sound but the actual slider). It might actually be working but you can't hear it because you're running the signal through the BT355's.

I'd try going back to a stock flash and see is the only thing I can think of.

 

Yes they slide the full range.
You can hear the change now in the treble and slightly in the bass. Before in the stock Ultra, no change could be detected at all.


Ok the experiment was a bust as I'd only get a flat curve at best anyway. Doesn't solve the tone control issue but does mean I go back to stock Ultra in any case.
Maybe flashing back will return the tone control.

 

Let us know, I suspect with the BT355's in the loop that it will indeed return the control

 

I had the BT 4180 and 4 speakers, (bags and dash) from the get go. I ran a flash that I thought sounded outstanding, I had no bass/treble, or fader, but it was not that big of deal to me. I was told the LL make better sound, I don't think they do. I would say it's equal in quality I had, and maybe a small amount less volume in DB. I do like my system now, don't get me wrong.....

 

So here's the latest....
I haven't flashed back to 0 amp 4 speakers yet but did have a long chat with Mike at BT. He had me to some swapping on channels to see if I had a bad harness. I don't think it's bad but I may have a bad ll. Doing the swap I had a noticeable drop in sound on it which he thought I would if my harness was bad. I double checked my other ll which seems fine and checked on both front and rear. I also had a molex connecter that I hooked up to a rca to 4 cable speaker cable and plugged it in on the rear channels. Wow what an improvement! But.....
On startup I have a tone coming through and a bit of a thump. When I move up in volume I lose a set of speakers . If the molex is on the front I lose them about half way and the rear just as I approach 3/4. The ll connection stays on throughout. Any ideas?

 

Considering you are using the RF flash why not replace the LL's with Line Out Converters. If you have the molex plugs that connect to the BO harness that would make it ease.

Another thing to check is with music playing wiggle the LL input wires where they go into the LL and listen for changes.

 

The plan is to re flash back to the 0 amp 4 speakers. I'm sure after I talk to Mike again we'LL have more to go one but I think I have ruled out the harness as was his concern and do have a bad LL as the white channel is nearly gone. These radios are so different from bike to bike that Mike is probably more frustrated then we are. He has more in the works as well which is going to be very interesting

 

That's the second line leveler with a bad white channel in the last two days here, I wonder what the underlying issue is ?.

 

Ok, let us know how replacement LL works out. It will interesting what Mike comes up with.

My thought exactly.

 

So my buddy has a 14 Ultra and replaced his boom system with a ss pn1000d with 2 LLs and fronts and rears. He went and had system reflashed back to stock (so they said it is) he had no bass and treble and fader but they all showed up on HU but didn't work when adjusted on the screen. After stock flash and a system wake up he regained some bass and treble but lost the fader completely (its not even on the screen anymore)
anyone have any ideas why??? I would image they flashed him to stock 0 amp 2 speakers but not sure.. The other thing was he didn't have the rears installed at time of flash because lids still in paint but we tried hooking them up like a bench test and got no sound at all.
So should he wait to have everything installed to reflash again?
or remover everything and put it back to stock and then have them reflash?
kind of at a loss here.
