NO, NOT to set them to 40Hz! I was just putting in brackets the lowest range on the LPF. Just for FYI purposes...
I would say to set them to 200Hz LPF to "meet" the doors (as Kai mentioned) or if you drop them to say 150Hz LFP then your introducing a "Gap" of 50Hz etc... |

Pavlo, thanks for detailed analysis of my setup. You are right its sounding worse with H660. It was better without H660. I went as per the document which it does support 4 channel auto ranging input. When I connected all 4 channels and kept fader and balance to center as instructed in the manual it went from bad to worse (after re-eq) however sliding fader away from center (either direction) improves sound a lot but rear is better then the front. Using remote if I drag stage to rear I hear more tones and dragging in front gets rid of those tones. CIC is still in HiFi mode.
I am going to put better 2-way mids on my doors soon. Not sure it will be economical to have another amp in the boot, also there isn't any space left in the boot. E60 is pretty tight. Does it make sense to add good two way front in the doors and use MS-8 with PDX-5 as H660 isn't looking promising until I move to 3 way setup. I am not willing to do complete rewiring of my car and full replacement of all the components, its quite pricey move. At the moment all I can afford is another "good" two way front door mids and perhaps MS-8 at max. Surprising H660's claim was to improve stock audio setup with minimum change not full upgrade of the car audio system. |

Also please suggest if something can be done in my setup without changing too many things. I am scared of wiring something from back of my car to the front, specially to the doors. It requires to remove the backseat and taking off too many panels.
In future I will perhaps put Morels/Focal K100 in the front doors. Can you suggest a better driver which isn't going to break the bank (like Morel/K100 will). Plan is to setup a true 7.1 system without going down BMW standard L7 route. This is what I have my mind: Front doors: Morel 4" two way or suggest a good choice Centre: Not sure pls suggest Rear doors: Not sure pls suggest Rear deck: Not sure pls suggest Underseats: SWS-8 MS-8 with PDX-5 Would that do? All I need to do is to stretch a wire for center speaker from the boot of the car and while doing it I can do cabling for the rear doors too. This would be a major project. |

Time for upgrade...
Now your system was coded (CIC) if I remember correctly. Your signal is flat so you don’t have that nasty EQ curve. So when introduce a system like H660 it took your flat signal (which it would normalize itself, usually). And then tries to create a bespoke one from its 512 band EQ, unique to your components. So by it introducing a new sound stage or re-EQing your sound made it sound worse, then something is not set up right. As a professional EQ curve (If done properly!) can never sound worse than a dull flat one, IMO.
So what could be wrong?

Either way – MS-8 or not, you really need to upgrade to HQ 2-ways fronts first. Quote:

ONLY if your car has a poor OEM EQ curve or is flat. MS-8 makes that claim too, but only because it has L7, very detailed 31-band graphic EQ with detailed crossover options and built in amp. H660 doesn’t have any of those. But, it doesn’t have a 4 x more price tag either… Last edited by Pavlo; 01-24-2012 at 07:43 PM.. |

Ok, got it. To start first I need new front driver first. I have come up with 3 choices.
1) Morel Ovation 4" - £240+ 2) Focal K2 4" or - £200+ 3) Vibe LiteAir 4" - £70ish Given the price range Vibe is making more sense to me. Its a good compromise. Does someone have any experience of using vibe speakers? I think 1 and 2 are quite pricey not sure if they THAT good. |

Having run H660 for a while now it isn't bad for the price it comes for. However I couldn't set it up for 4 channel use. There is no way I can put rear channels in use at all. Has anyone setup all 4 channels to work with H660 coming from CIC coded to the HiFi.
When I connect just the front one then the car lacks rear PDC audio and when I connect both rear and front then for some reason after calibration there is very little sound sound and no bass whatsoever when the fader is kept in middle (as it was while calibration) but if fader is moved towards front or rear then bass returns back but I believe brakes calibration and sound stage is dragged back. Just to let you know when all 4 channels are connected to H660 I didn't connect H660's bass line anywhere. Has any one tried H660 in 4 channel setup?
