DSP Removal

I've installed the magic box, but I still feel like the DSP is affecting the sound quality. I've spoken to my local dealer several times and have even sent them the RF bulletin describing the flash settings for removing/adjusting the DSP for aftermarket amp installation, but they insist that they've never heard of this issue and that any flash done to the HU for this purpose will reset it to the original software version, thus bringing those problems back. Is there any way to do the flash yourself? Are they accurate with the excuse they gave me, or just trying to avoid doing the flash?

jpalm ,,,,,,,,

go to whichever dealer you need to and have the radio flashed back to stock, which is "2-speakers NO-Amp" on a streetglide and "4-speakers, no-amp" on an Ultra or Ultra limited ,,,,,,,,,,

very simple for the dealer to do ,,,, and the fairing does NOT have to come off ,,,,,,,

yes ,,, that is a good way to paraphrase it ,,,,,,,,

then when you add ANY aftermarket amp, you just need to dial some of the boomy base out of the amp, using the amplifier crossover frequency adjustments, to tune the speaker a little for the acoustical fairing speaker enclosures that come from Harley stock ,,,,,,

when using a J&M ROKKER XTP amp like this one, http://www.jmcorp.com/ProductDetail....=JAMP-250HC14P ,, I have optimized the DSP software controls inside the amp, for the stock Harley speaker enclosures when using these J&M ROKKER XX speakers http://www.jmcorp.com/ProductDetail....CRK-6652TW-RXX ,,,,,,

The reason I ask is I'm getting ready to upgrade my amp and speakers and I just want to make sure if I haven't done any flashing yet my 14 SGS should be in the stock configuration John is referring to correct? All I would need to do is install amp, speakers and magic box and I would be good to go.

I don't know how the stereo would sound without the Magic Box because I've never tried without it, but it definitely does sound like there is still some - albeit minor - effect on the speakers from the DSP, even with the Magic Box. Of course it could be that the pods don't allow for proper bass response, or some combination thereof.

One other thing. JMJohn has been a tremendous help to me, even though I'm not using his products. He may have some insight on your specific situation, and I think he may even have a solution through his amps, I'm just not in a position to buy one right now.

The CW amp I'm running is pretty similar to the RF, from what I've been told. Have the gain set about 40% and hertz around 150-175.

did not need to flash and for the money spent i couldnt be happier.

For me it's been very finicky. Most songs are loud and clear as a bell, but sometimes I still get some low end distortion, but it could be the pods as well. I think the best way to truly know is to find some way to run them without the pods, but only BT has the brackets and they only sell them as a package with the 7.1 upgrade.

also keep in mind the scource of where your music is coming from. (pandora, xm app, or if you download music) some sources seem to sound better than others. just my opinion

Definitely noticed this. Songs that I've downloaded from iTunes are much clearer than those that I transferred over from elsewhere.
