Open the unit and look forr the fuse to the unit. If power comes to the sub woofer drive board , check for the rail voltage to the IC.
Check the resistance of the subwoofer, make sure it i working.
If supply is coming to board, check for any signs of crack on the PCB. If not check for any loose connection on the IC.
If posible use a good soldering iron to solder suspected points in the board and the IC pins.
Since your set was working we must use the logic to look for a fault that occured during the transit.
if all the tests prove corrrect, then we can suspect the IC.
Make sure that there is input audio signals to the IC before you can confirm.

How it can be connected to a stereo amp


hi,
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.

if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.

if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)

your sub woofer is designed to work , both at low level and high level input.
ok

In DEC 1998 I bought a Gateway PC with a Digital Media Theater, P/N 7000787. In the meantime the speaker in the sub-woofer got damaged (because of age). Is it possible to disassemble the sub-woofer and replace the speaker?
Where can I buy the same or a very similar speaker for this sub-woofer? Thanks, Andy Szekely

My car's sub is ''sub-par'' my expectations


Hello css42103,

You did not specify the impedance or the model of your Audiopipe replacement woofer but if it is the TS-V6 DVC 6.5", then the impedance of each voice coil is 4ohms. If you wired the coils in parallel, you now have a 2ohm load to the amp. At 2 ohms, the amp tries to produce more power, and even at moderate volume, can be driven into clipping causing distortion. Not good for the amp. Definitely not good for the woofer.

I'd try wiring the woofer coils in series and see if it stops cutting out.

Hope this helps.

Speaker errror message


The usual fix for "Speaker err" message is to simply unplug the sub-woofer power cord to reset the speaker diagram, plug it back in and remember to "match the negatives to negative, positives to positives" and never try to replace the original speakers with anything but equivilent speakers, adding on more speakers can cause the "Speaker err" message and an inoperative system.
