Default Logicrap subwoofer problem

Hi i also have been following this thread for a while i have a problem with my z5400 sub the amp i think has blown all the speakers have sound coming out but nada from the sub

there is not even a faint sound so i think the amp for the sub is blown and the amp for the speakers is still working.

at the moment i have the sub set as passive cut the cables to the driver and using the FL and FR to power it but it sounds awfull very low no bass

so i have bought a Mordaunt short ms409w bash amp that i will hook up to the driver problem is .

the amp only has low level line in so i cant connect it to the LF and RF speakers outputs in the z4500 i need to find a sub preout

can i get this from the dSub cable or does anyone know were i can pull a sub pre out connection from

i have included an image of the amp

Its ok i managed to fix the issue turns out my amp in the 5400 was not blown a grey wire on the control pod became loose when i resolderd the wire back the amp was working ...

for anyone who wants to add a new amp the ground wire for the sub is a thin blue wire in the control pod

hello there everyone.

just came across this thread and still trying to clear up for myself all the good info everyone is supplying.

i would like to ask you a question before i start doing anything, as i dont have no speakers no ampl or anything but might consider getting some cheap podless z5500 that is available to me atm.

so my question is if it will be possible with these modifications you speak of to get the podless z5500 to work with a PC audio card , some 5 chann Creative for instance.

thanks

Hello,

Finally i have a podless z5500.
I just want to share my knowledge.
What i did is hooked up my z5500 speakers to me receiver. The receiver i use is a onkyo HT-R518 and it has a 5 channel output (5x 130 watt 8 ohm).
Also there's a sub pre out.
I bought a db15 cable and connected a rca cable to it.

I did this the following way:

- the + pin of the rca cable connected to pin 2 of de db15
- the - of the rca cable to pin 6, 7 and 13.

What i also did is i used a resistor, one i can set manually between 0 and 10Kohm.

This way i can tune everything on a verry nice way.
The receiver isn't THX certified but the sound is WAY and WAY better without the pod and instead of using the pod using the receiver.

Take a look at the pictures if you want.
Also modded my 5 z5500 satellite speakers

Default Z-5500 Bass

Does anyone know how can I increase power to the subwoofer internally without the control pod?

Question Z-5500 Subwoofer

This is the second z5500 sub woofer I have modded to work without the control pod. The first one worked perfectly, but with the second I'm getting a lot of mid range frequencies from the sub woofer. Does anyone know how to solve this or have any recommendations? I thought about putting a treble blocker/low pass filter directly on to the sub line. What is the crossover frequency of the sub woofer?
