Question about JVC SPPWA670 Subwoofer

Open Question

I have a JVC-SP-PWA-570

This sub used to go off and on but now it blew the fuse which is 1 amp, it even blew a 5 amp fuse. I experimented with a 20 amp fuse but as soon as you apply power the speaker makes a humming noise. I read the coils on the speaker itself it reads like 8 ohms. So i am guessing the problem is in the transformer or curcuit board does any one know what to points to read and test? Is this a common problem if this model?

SOURCE: JVC Subwoofer problem.

You may have a break in the wire. You can find out by slowing moving your fingers down the wire until you notice sound coming from the subwoofer. You can fix it yourself by cutting about an inch away from the break both ways. Then cuttings some of the wire off, so the copperwire is exposed. then wrap the two copperwire ends together and seal it with elections tape. or Try replacing the 60 watt subwoofer wire.

SOURCE: my jvc subwoofer inner speaker windings blow up

I would suggest to buy the entire cone speaker because the inner windings is harder to find or not available.
The cone speaker part number is: CR160058-01. Try contacting this website to find the cone speaker or you could find a cheaper speaker cone with the same dimensions and wattage.
I can also send you the service manual for this subwoofer.

Have a JVC sub SP-PWM606 all speakers work except sub. found a blown cap on what I assume is the sub's amp replaced 2 caps- still no sub


Sub woofers are basically mono amps. It's likely that either a fuse has gone, on the sub, due to the blown caps. Or more likely the main power amp device of the device blew the caps. I suspect if you replace the IC or transistor(s) on the heatsink then the device will come back to life.

Why does the fuse blow?


try a different sub first, the fuse difference is not crucial but should try to use the one recomended by manufaturer

Why does the fuse blow Instantly?


Link for the service manual: http://elektrotanya.com/pioneer_vsx-305_405.pdf/download.html On page 50 of the manual (36 of the pdf) it says for the "Sub woofer pre-out jack (Not available on the VSX-305 model) If you want to boost the low frequencies, connect to a subwoofer power amplifier" Your model will not drive a sub-woofer with out another amp. His sub may be a powered sub?

The subwoofer SP-PWM505 won't turn on.


Make sure its not set to Auto. Also check for a fuse in the back. Unplug the amp side and with the sub plugged in touch the RCA. You should hear noise from sub. Try this last. Some may say this is not good for the sub. Im in the business and never have seen it cause a problem

My kenwood KAC-7204--- the wiring is hooked up right, I just got a 2000 watt max sub 1000 watt rms, i was running the amp in bridge mode and it ran for 1 day than it turned off. I checked it and the fuse...


when i was running my sub off bridge mode this kept happening to me. I ended up just running two subs and for some reason the fuse stopped blowing. i think there is something wrong with these amps.

Well it's temping to put in biggfer fuses as the problem gets worse but the size of the fuses are to keep you from burning things up so you've from your probem with a 30 amp smoke test. The raditor fan wire is melted somewhere in the wire harnes to the wire for the trck lock or even key on circirts. the likly place to look is inside the stering collum. It takes the skills of removing the steering whel and the lcok plate and even then thats does'nt have to be where the problem is. You need to look under the dash after you remove the covers and use you nose to smeel for the burnt wiring and open up any thing the smells like it's been hot and anything the appers melted together. once a harness is found melted you need to seragete all the wires in the loom but don't cut the wires justy seaparte them. once you think you've got then all pulled apart so no bear wires touch each other or any meal parts put in the correct size fuses and see if you can connect the battery with out a spark. if you can you may then start checking to see what works and what does'nt.. This all sounds like too much work or too hard to do then you'll need to pay someone theat knows alot about car wiring problems to do it for you. I'll been doing this kind of work for the last 20 years and a'm alawys finding new things that are fried and burnt up. We all charge by the hour to do this work so the most experieced mechanic that works on cars like yours will probly find and fix the problem the fastest. therefore they may charge more per hour but their likly to get it right quicker and it'll stay fixed after they fix it.. This is the most likly kind of work to go sour after it's fixed cause they might miss a circuit that you use and they did'nt try. and as soon as it burns again it's back to the drawing board and if big fuses are use the fire can take the whole car.

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.
