By main unit i assume you mean the head unit or the CD control unit.

the answer is YES,

bose sell a part that will conect your ipod to you r bass box direcly ( or at least they used to) it was not passily powerd by the ipod however as the i pod can't maintain the current necessary to sustain the power up of the amp's control circuit. so it was powered externaly.

the answer is. you need 5 v dc at 500ma capacity on the centre pin to power up the bass module and thus bring the bassbox to life, the remainig pins carry L/R and a control voltage to adjust the volume, i will need a bit of time to find out which pins exaclty do what, as i cant remeber off the top of my head, but i'll bet you'll find the answer on a diagram if you do a search on the web. please also note that the 5vdc can also be varied between 1.5vdc and 8.5 vdc to adjust the volume of the bass box and the system overall, and so that is the major problem for you to solve if you want to build your own amp. ( maybe get your hands on a second head unit ( CD 20 ) cheap on ebay or something or spalsh out and buy a remanufactuerd one from bose. but maybe thats not what you had in mind .
:-) have fun.

Benwin 5.1 surround sound system Humming loudly without anything pluged into it!!!

It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably

be on the power supply.

If it is only on the main SUB unit, then it could be the amp itself.

But check for power supply capacitors that supplies voltages to the

amps.Check for amp output DC voltages too.

The protection message appears only when a short is detected. Since you get this message only with the sub connected it means that the sub is shorted and you will have to repair or replace it.
If you decide to repair you should open it and test the electronics - amplifier and power source - of the sub.

Can I plug just one subwoofer into my Yamaha EMX88S? What kind of sub do I need to get for it? Do I need to have 2 subs plugged in for it to sound right? Do I daisy chain the subs with the A15 speakers I...

it is not reccomended to daisy chain passive subs with main speakers, because there is no crossover unit involved. you want a sub to have a crossover frequency around 100hz, so that only frequencies lower than this go through the subs, and not in the main speakers.

you could get away with 1 sub plugged into the mono output on the front, subs dont have to be stereo. you would need a self popwered sub, or an additional amplifier+crossover for passive subs. your best bet would to be to get a powered sub and hook it up to the front panel mono out. powered subs usually already have the crossover built--in.

The light on the refrigerator side of my Sub Zero does not work

The light switch at the top of the door frame is bad. it controls all the lighting including the display for the board. you will have to remove the grille up top, remove the cover over the 2 switches, and replace the switch that is all white. the one with a black back is for the fan and rarely goes bad. Just unplug the unit or at least turn it off before changing this switch, as it is live any time the unit is turned on.

How to clean drain tube at the bottom of the refrigerator?

Sub zero drains dont usually cause a cooling problem. You could be having that drip because its not cooling enough. Check to make sure both doors close completely, check light switches-do the lights turn off? You will have two or three fans on this unit, one by the compressor, one in the freezer, and possibly one in the fresh food section.

If you have further questions, visit my website and send me a question.

Jbl sub 135 motorboating b4 warm up JBL sub135 I never heard it called motorboating, but that is a good description of the sound, It's like the sub is trying to output sounds which are not in its range...

Turning the unit on without any input signal, the speaker did the pop and scratching sound. I found on the limiter board ( small pc board on the main input pc board) that there is a wire jumper on the back side of that had a cold solder joint. You will have to clean up the glue that was used to hold the wire on the back side of the board. I just replaced the wire with new one.

Look at the +15vdc off of Q117, I moved it to the left side of the pc board and added a heat sink to the unit. The 1 watt resistor created some cold solder joints that you will have to check.

hope this helps
