Has any one used the DSP Line Level Shifter from Cycle Sounds with aftermarket amplifiers? I get the hard work and efforts by Hog Tunes and J&M on creating new amplifiers to level out the crap coming out of the stock head units at speed.
I removed a ton of audio equipment from my 2011 SG. I want to install the amp and speakers in my RG Special and have just heard about the Cycle Sounds (Magic Box) . Looking for some real input here. Did it do the trick or am I not going to be happy with the results. Ed is kinda out there in his engineering, but his stuff works.
When you talk about the "crap" coming out of the stock head unit at speed, it helps to know how it works and what that "crap" is. Then like any other problem, you come up with a plan to solve it.
The stock head unit already has an internal amplifier. Just like any amplifier, it amplifies EVERYTHING that comes through it and sends it to the speakers. So if you have a crappy source, or are planning crappy quality music to start with, it's gonna sound like amplified crap coming out. Also, if you take that crappy signal and send it in to an aftermarket amp that's pumping 100w/ch, you're reamplifying a signal with all of the crap still attached to it. This is the problem that having RCA (pre out) jacks on your head unit solves. The signal is sent out BEFORE the head unit amplifies it. HD will not put preouts on their head units.
Think about how an old vinyl record sounded with the static and such. Then consider amplifying that signal. That's what's happening when you use high level(speaker line) outputs from your head unit to your aftermarket amp.
A line level converter or "magic box" takes the amplified signal and strips the distortion and amplification from it. Kind of an aftermarket preamp kit. This gives your aftermarket amp a clean signal to amplify, resulting in a much more clear sounding stereo assuming your speakers are quality.
Find a seat you're gonna do the majority of your riding with.
Find a properly fitted windshield. The top of the windshield should be somewhere between the tip of your nose and the top of your nose, depending on the characteristics of the windshield, while sitting upright in riding position. The stock RGS windshield looks cool, but sucks for riding and music.
Once you've attacked these two areas successfully, then do some research on this forum and decide how much you want to spend for your stereo system. I promise you, there will be more boom for your buck this way!
