    Same problem. I noticed I could get it to work if my switch line was BELOW 11.75 volts. With the car running, lights on, AC on, fan on high, I could switch on my rear window defogger and it would come on. As soon as I turned the fan down or the AC off, sound was gone again. With the car off I could turn on my lights or turn the fan spped up or even the 4 way flashers and it would come on. I could understand if it worked with a higher voltage and not with it low. I will keep working on it and let you know if I find anything out.

    My 03 corolla is having the same exact issue. My friend has a 06 xb and he had the same problem. What he did was tie in a 12v zenor diode to the power out on the clarion eq. this fixed his issue but not mine. My friend also has a late 90s 4 runner and he doesn't have this issue

    Had the same problem here. A quick fix I found was to disconnect the EQ from the +12v line coming from the battery and supply power by connecting the Remote lead to both REM and +12v ports on the EQ (a simple wire bridging the two did the trick). EQS746 works great now.

I had the same problem with mine I had an old Kenwood EQ hooked up an it worked fine. Then I hooked up the clarion EQ the same way and I had power but no sound. I took it out and exchange it for another one and the same thing, no sound. I don't know why my Kenwood would work in my car but the Clarion wouldn't. I could use some help too.

Head unit connect

You will only be able to use this EQ on the front or the rear speakers. You will have to get another EQ if you think you need one. Usually, the front speakers of a car's audio system are the smallest and the rears are larger. You really do not want an EQ on the subs. If it was mine, I would hook the EQ between the head unit and the rear speakers. If you feel this does not sound right, you may need, but I doubt it very much, to get another EQ for the front speakers. Good Luck

If your system is equipped with a tape monitor loop, you can switch the EQ out of the circuit by disengaging the tape monitor switch. If the EQ is connected to the pre-out / main-in jumper, you would have to defeat the EQ before you hook up a conventional speaker. I don't believe the EQ has a defeat switch - you'd have to rig a bypass.

Once defeated, if you have a system equipped with a Speaker A / Speaker B selector, the smaller speakers could hook up to the second system. If that's not possible, speaker switches are available for reasonable money. It is very important, though, that the 901 EQ i defeated when using conventional loudspeakers.

I want to hook my bose 901 VI along with EQ to my Luxman R117 Receiver and also run other speakers from the same receiver. Is this possible?

If you are using the Bose Equalizer to optimize the sound of the 901s by going through either a tape loop or a pre-out/main-in loop, then the only way to do this without also equalizing the sound sent to the second set of speakers is to manufacture a "zone-2" output from the Luxman.
You'd probably need to split the send from the Luxman's pre-out before the EQ and send it to a second power amplifier for the second pair of speakers (if you want the Luxman's volume knob to control both speaker sets) or from a tape level output (if you wanted independent volume controls for the two speaker sets.
The whole EQ thing made 901s difficult to use on vintage equipment with only one "zone" audio outputs. Unless you want to use the Bose EQ on the second set, too, you can't do it satisfactorily without adding another stereo amplifier. But, go ahead and try it, you might find that you actually like the odd EQ that the 901s EQ gives to the second pair!
If it were my decision, I probably would not do it without a second amp, but it's all about what you like, my opinions really don't matter in your house, do they?
Have fun

start with the tuner, hook up the equalizer to the tuner, then on the rear of the equilizer hook up all the peripherals except the amps which will go to the tuner outputs and all will feed thru the tuner to the amps and out to the speakers
