Hiya, start by checking the power cable, then check the fuse in the unit on the pcb. If blown, replace and if it blows again then problem could be either Power supply or the amp outputs. If it doesnt blow, stays on but no sound, problem also likely to be output stage. You will need someone with experience to check outputs, etc and a meter though. Hope that helps a bit.
Best of luck

Very minimal sub-woofer power


The speaker is most likely blown out, and if it is there is no way to fix it, you will just have to replace it

Subwoofer is crackling - maybe blown? Was


Crackling is usually a sign of a blown speaker or a misaligned coil.

Both can be very difficult to fix themselves.

However you may be able to buy a new speaker .

You would have to dismantle the sub and remove the broken one first.

A goo hi-fi shop or even musical instrument shop may be able to help you with that.

You would need to know the impedance of the blown unit along with its frequency range. That information would usually be in your user manual.

Its not a difficult job but if it is a powered sub then be aware of electrical hazards and ensure it is disconnected from all sources before attempting any work.

Man


it is impossible to make a dual 2 ohm sub only be seen as a 2 ohm load with out damaging the speaker. there is a way but if i tell you how to do it, then "WHEN" not if but definately when you blow up the sub you will be ticked at me and expect me to pay for it so i am bound by law not to disclose it. being mecp certified and an authorized distributor makes me liable for any
mis-information. and the only way to do it is the worst way to do it that may possibly even cause the amp to blow or even worse the sub can and most times does actually catch fire inside the voice coil.

you have to have a dual 4 ohm.sub to get a 2 ohm load at the amp

When the lamp does not light: Check for disconnection of the heater lamp and thermostat. Check the interlock switch. Check the power PWB and the MCU PWB lamp control circuit.
Clear the display of self-diagnostics with SIM 14.

Hello Ronaldlora

Hi, this is a particular problem for this speakers, and subwofer, it is a resistor inside the sub, you have to fix it in a repair shop, or ...sadly, change for another model of Creative Speakers, for example one good one is the 7800 Spk. good ones.
but like I say is a problem that creative labs is aware too.

Amp shuts off


is this a new problem or has it always done it?? it mos tlikely needs repairs, but try this first. Hook up ther + of one sub to the speaker + on the amp. Hook the - of that samne sub to the + of the other sub. Then connect the - of the other sub to the speaker - on the amp. This will run the speakers in series and will put alot less strain on your amplifgier. It will not "hit" as hard but it sbetter then having it shut of fall the time. I would also make damn sure that:
Your ground wire is large enough and properly grounded. It should be BOLTED to a solid poiece of metal on your car. Use a screwdriver, whatever so scrape off any rust as the connection should be a clean, BARE METAL connection. Next make sure your power wire and fuse are ok. If you are using round glkass fuses, replace it even if it looks good. I have seen those fuse smelt the solder in the ends. They can look great but really be bad.

SO go through all the basics and if it still gives you problems then it needs repaired. Please dont rate me un-helpful.

Pioneer amp and sub problems


That's a 4-channel amp, not a 2-channel, which makes me wonder exactly how you have it hooked up to your sub. Is the LED light on the amp coming on? How many subs do you have hooked up to it, and how is it wired?
