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?

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.

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

I have a 2004 Chevy Cavalier. A couple of months ago, just after starting the car one day, the 'check engine' and 'trac off' lights both came on. I immediately shut off the car, waited approximately 5...


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.

My JVC 100 watt amp blew a fuse 125v - 6.3a. is there and alternate replacement fuse?


You can buy replacement 6.3 amp fuses at Radio Shack, but in a pinch you can substitute a 6.5 amp fuse. It's only slightly higher in value, so it will still blow soon enough if there's a problem.

However, this doesn't answer the question of why the original fuse blew. Fuses very seldom "just go bad", so before you start replacing a blown one you should find out what went wrong. Check the power supply rectifier diodes and filter capacitors for shorts. They sometimes break down with age or because of power line surges. Also look for shorted output IC's or transistors. If you can't do this yourself, see if any of your friends have experience servicing or let a professional fix it.

Please, don't just stick in larger fuses (or worse, wrap foil around them) when they blow. Many times I've seen what would have been a simple repair turned into scrap that way. Hope this has helped, and thanks for using Fixya!
