The LC2i should handle the Logic7 outputs without any sweat. So let's go back to the particular problem at hand of 2 different EPS systems causing the exact same LC2i malfunctions all of a sudden. |

i have it set that way because that's what sounds best if i raise the 100hz (which is the lowest) the mids start to distort if i raise the volume same if i raise the bass this way i have the sub handle the bass and the mids sound good when i raise the volume

Bummer... I was hoping that might have been a fix for us.

If the bass adjustment in the iDrive is set to relatively high levels then the LC2i levels need to be set to complement those levels -high in the iDrive, low in the LC2i.
If both levels are high then clipping will be induced. The LC2i is also a line driver capable of up to 13V output. The AccuBass feature does not help to set the LC2i accordingly with the EPS system. However as long as it is disabled then it should not interfere with the LC2i Bass adjustment. The LC2i Bass adjustment should simply increase the level of voltage coming from the OEM woofer outputs in a linear fashion depending on how much you turn the Bass knob/gain. AccuBass increases the bass output dynamically (supposedly filling out the bass "holes" in the music), which it is not good if you also are increasing the bass adjustments at the iDrive. |

You can always try one channel, but in my opinion this will be masking the real problem.
I will be getting a pair of custom Navone 30V passive LOC for you and Tech each to try sometime late this week. I want to know what happens when the active LOC is replaced with a passive (no line driver, no Accubass) in your particular amps. |

Sorry i used L7 because i dont know what else to call the subs underneath the seats, I have the individual like most M3 owners, Well idk why i had the issue but it lasted for 2 years and i had changed several amps and subs and LOCs, nothing would work until i tried using the signal from only one sub and it never had any issue after that, my system hit harder than ever and never have any amp overheating, or subs blowing or LOC going out. Guys give it a shot, im no genius at this and Technic knows alot more than i do, but this worked for me!
PS: I had two subs running in parallel i believe. Also with the adjustment i provided, the LC6i i used would be able to go at least half way or more without distortion. |

I have never been a fan of head unit bass boost, as it is an easy way of introducing distortion into the signal path. If you want to "boost" bass, always do it at the amp, because it has the most available "headroom". As far as the EQ goes, not adding any boost in the bass range is actually not counterproductive. Especially in your case, where the LC2i seems to be close to maxed out, adding additional voltage into the LOC through boost or EQ is to be avoided. You can still EQ, but you do it by cutting, and not boosting. For example, if you want to boost the 80Hz range, you can cut the surrounding frequencies and then increase the gain on the amp accordingly.

I have a spare lc6i I was using then realized it had too many channels for my needs, and replaced it with the lc2i
Want to try it?

i would use some sort of slope for refined bass and lose the infrasonic unless your aiming for mids, just my 2 cents

I have a brand new, third LC2i sitting that I can use. I was just wondering if the LC6i was of any higher quality and/or could handle more input voltage over the LC2i.
