| hmmm as expected "The only way you could get a seperate sub control is to use the rear speaker out of teh HU to drive your rear speakers, then use the rear RCA out of th HU to drive the sub (via an amp) and the front RCA out of the HU to drive the front (via an amp). Does your HU allow it to be programed in this manner?" the sub is being driven by the RCA for rear speakers. I asked blau service personnel about subout option. and they said that a special Y-cable with wiring harness needs to be connected to the rear of the HU. Previous safaris had those Y cables with harness builtin from factory.. but the new dicors dont have this facility and without proper harness in place, the wiring needs to be cut, which can lead to warranty issues as per them. So now i am trying to find out where can i source the wiring harness for my dicor with a option of Y cable to serve the sub at LPF of 80HZ or 100HZ. Finally understood also that the HPF can be set to 200HZ for the 4 speakers to play good midbass from HU  and as a result a achieve a desirable crisp soundstage of music from my investment.If any of the gurus is knowing about this wiring harness and Y-cable stuff do's and dont ...let me know your thoughts ps: the amp is set under the drivers seat, shielded by the underseat carpet with air to move around it..is it a correct placement or it should be moved somewhere else like bolting it in the luggage area or somewhere. |

Blaupunkt - Head-units - MP3 Head-units - London MP37 given the components you have above I'd suggest using the amp to drive the sub and using the HU to driven both front and rear speakers. I assume that the "rear out" of the Hu can be "configured" to drive either a sub or rear speakers. I suggest you configure tis to drive the sub then connect the amp to this output and the sub to the output of the amp. once that is done make the change the setting i have marked in BOLD to 0. Listen. Write down what you feel is missing. change only that and listen again. repeat till you get to where you want to go with your sound. | |

1> the HU can be configured to use SUBout, using a Y cable with a harness which connects to the preamp out of the HU in a special way wherein it can connect to the L/R channel going into AMP. Situation is the HU is driving frnt and rear speakers.... there is a blau RCA cable which has 4 cables and one wiring harness which is connected to the preampout connecters. The cables read front and rear pair. The rear channel is connected to the amp and then to sub. 2. i didnt understand "configure HU" 3. I did what u said to set to 0 in bold. my understanding is that i am missing the things between 100 & 200HZ range eg. this song Youtopia in this song if the bass is set to 100HZ, i miss out the keyboards and the sitar playing and hear drums, and treble. (link is for reference from the orignal song) Another song is Pehla Nasha song from "Jo Jita Wohi Sikandar." i can hear the boom base and highs and less middle unless i set the base to 200HZ. and once i do that I lose on the base. not sure if this helps across  However I will listen to more songs with point no 3 in order to achieve a balance Last edited by Rahulk76 : 2nd July 2007 at 15:46.

Or, set the sub amp gain to zero (on GTA2; I assume that your other speakers are connected to the HU) and bring the HU volume to a level that you are comfortable with - you should be able to hear everything else other than drums etc. Now increase the gain at GTA2 till you hear everything the way you want it. | |

The specs of Blau London MP37 (Blaupunkt - Car Radios - MP3 Tuners - London MP37) say Amplifier Parametric equalizer Number of bands 3 Sound presets (music) X-Bass Preamp-Out 4-channel (2 V) Aux-In 2 Front Aux-In Sub-Out: var. gain/frequency That would mean the Sub signal has its own pins in the rear connector, and a separate cable to connect the sub amp. The manual should show which pins go where. The connector is quite commonplace, so the 'special cable' can be easily fabricated if it was somehow missing in the cable set. The cable is common to a lot of Blau HUs, such as Bahamas MP46, St.Louis MP56, Memphis MP66 etc. | |

| Senior - BHPian  | As DerAlte said, the Blau HUs have a flat-type connector that terminates in RCA female sockets. Quote:
Or maybe the 'Y' cable is being used probably to get both the front & rear pre-outs to feed the sub-amp. Then the sub would play regardless of whether you faded to the front or to the rear. But then even for this you'd need 2 'Y' connectors ??? | |

4+1 Channel Preamp Output Adapter Blaupunkt 5-CH Preamp Adapter in the above pic.. i guess its the yellow cable which will feed the sub throough amp....(looks like this is also one of it Blaupunkt Power and Sub Out Connector) Subwoofer Output: In addition to the 4-channel preamp output harness, a separate mono (single channel) non-fading subwoofer output is provided on the power harness.(which one i need to understand this) You can control the subwoofer output level from 0 to 7, and the frequency of the low-pass filter can be set to 80Hz, 120Hz, 160Hz, or Off (no filtering).

To know exactly which one to get, look at the pin-out section in YOUR Blau manual - go through the WHOLE manual (Jap, chi, russ and all such pages if you don't find it in the English section - mine had it under Japanese! Shows the rear view of the HU with pin legends). You should be able to correlate the connector shape and pin details with the connector of the cable. Non-fading = HU has already extracted the sub signal from the other channels in a way that Fader will not affect the sub volume (dedicated signal for sub amp), instead of the USER having to extract from Front / Rear signal via a Y adapter. There is also a single wire separate signal for remotely controlling the power of the sub-amp, so that the sub-amp does not stay on when you switch the vehicle off. | |

If so, OK, you found the right cable (your first/second link, not the third; another one is this one: http://www.bluespot.co.uk/stock/preamp2.asp). The Sub-out is a bit of trickery in both cables above - the loose white wire with the brown ferrule and pin (not the red one without a pin) connects to the A3 pin (connector A, pin 3, actual Sub-out pin) whereas the rest of the connections (yellow connector) go into connector C1. The cable from your 3rd link will send your installer into orbit! Come to think of it, he could actually fabricate a cable connecting to A3 and A8 and an RCA at the other end, but... forget it, if he got himself into a tangle about Y adapter and all, maybe he is not the type. | |
