He said that the leveler would lower the voltage which their system didn't need. That basically their system worked best this way. He also said I wouldn't blow the amp, that it had a protective feature to keep that from happening. He did say it was possible to blow the speakers using a bad source.
Just passing along what I was told, because I don't know, just trying to learn. And that's why I ask so many questions.

U do know that the dude at ARC is selling product correct? The fact that u have to have the bass at minus 5 might be telling u something about a Jerry rigged work around. And I like ARC stuff.

IMHO, AVC does not have anything to do with the curve. It's is recommended to have it off so that ur not inadvertently pushing ur equipment into the land of magic smoke. If u have a conservative tune and account for the volume gain then by all means use at your own risk.

I do understand what you are saying. And they're all trying to sell product, but funny thing is he says I don't need to buy anything. I guess it will be one of those things that if it works and doesn't give problems, then good. If it gives problems, I have paid for more education lol. I do know some of the bike stuff is advertised to seem easy to install, then when you get it you find out what they didn't tell you.

FYI Wam I had that same setup in my 15 RGS last summer, I put just over 10,000 miles on it in all kinds of weather. Right or wrong I didn't have any problems and it sounded good to me, loud and clear at 70-80 mph.

Ill throw my 2c into the mix. I have done a couple different setups on my 14 Limited. I originally went to a mobile audio store when i wanted to upgrade, they recommended the arc kit which consisted of a 600.4 amp and 602 speakers. After researching here, I learned other options and about the Bt355 line leveler.

I asked the sales guy about the line leveler and he knew nothing about it and never used one. Long story short, I went with the advice here and did the BT355, a JL 280/4 amp bridged and a set of Hertz HCX 165s. The sales guy wanted to hear it. He then began using a line leveler on their installs. He said he was impressed by the difference in sound quality between using one and not.

I have since changed amps to an Arc 600 and did rear speakers also. I also upgraded the line Leveler to an Arc PSM. He hadn't used one of those in a bike either until He heard mine. He is now recommending those on his installs. You guys, through me, must have educated this guy. They have a great rep in the car audio biz, but they sure must have been lacking in the bike side of things.

Great feedback brother!!!! BT put some thought into that BT355 and yes it does make a noticeable difference.
Other options available but just depends on trusted resources for the flash strategy or a bit of sweat equity or a buddy in the know for the DSP.

Thanks T..

I really like the DSP. HHHHUUUUUGGGGGGEEEEEEE learning curve, but I think it's worth the effort. That's really easy for me to say though. I had help at the fall Midwest Meet & Greet. Thanks Matt!!!!!

Edit. And thanks to all of the usual suspects for all that you do!!!

The avc has absolutely NOTHING to do with the built in DSP curve. It’s just an attenuator. the use of avc with ANY aftermarket system WILL damage the speakers.
You will either need a aftermarket flash to flatten the integral DSP , a BT line leveler, a JL fix, or external DSP with manufacturer provided counter calibrated software (like the arc psm) to get the internal radio DSP flattened.
It’s really just this simple.

ok so maybe this is a dumb question, if I have the BT355's, which I do, can i safely now use the avc?

It's actually a brilliant question. I have yet to see tangible technical data surrounding the HD AVC but have seen magic smoke.
Is it because of AVC technology or is it because of SVC technology?

The absolute best strategy is to not use it, but it would be interesting to see defined operating parameters for the folks that may want to play in that sandbox.
Most guys run their shix pretty hard thus an involuntary bump in volume can fry stuff pretty quick, but what specifically is happening behind the curtain?

I finally got my bike out this weekend after waiting as it seemed for ever after the new audio set up was finished. I rode for a good hour playing with the volume, treble and bass on a lot of different tracks before I realized I had the avc on 3 bars. I turned it off and I did notice a difference in the way it sounded being a lot clearer. I set the gain up originally without the avc as we all do to peak out the amp so I think it pushing the speakers over the top. I suggest that if anyone is going to try to use the avc then they need to set up the amp as such dropping the gain a bunch and just add gain after riding with the avc on until it peaks using the avc. A lot of trial and error to get it right at that point. Just food for thought.
