Check the yellow wire connection on your wiring harness... This is the wire that provides continuous power even when the ignition is off. This is how the radio remembers presets/time and such. Every time you turn off the car, the radio "resets" because you dont have the yellow wire connected to an ALWAYS HOT wire.

If you cannot find a hot wire, then you can run a wire from the yellow on the back of your radio directly to the positive terminal on your battery. Dont worry, it doesnt draw enough power to run your battery down.

Most cars have a cigarette lighter or power port somewhere that is always hot. You could always run the yellow wire off of one of these.

Just find a way to get the yellow wire on a hot wire and your stereo will remember the presets.

I ended up with one piece of a Teac model CD-X8 MIcro Hi Fi System. you can see what the whole system looks like at http://www.amazon.com/Remanufactured-CD-X8-Wall-Mountable-System-Subwoofer/dp/B000B65GV6...


Yes - you have the sub-woofer. It is a powered sub-woofer with a built in amplifier for both itself and a pair of small satellite speakers. Frankly, given the low cost of the whole system it may not be worth selling on ebay due to the high shipping costs of such an item, but I imagine you could get $30 for it or so on local craigslist or something, assuming you have no use for a sub-woofer...

The sub-woofer amplifier is probably blown. This is a separate circuit from the other channels. It will need to be repaired. It is likely a bad transistor or open resistor that over heated.

Blown Amp AC?


Unfortunately, these older systems lose value rapidly and the cost of repairing problems like this can end up being as much as buying another system! Actually, you might be surprised to learn that JVC Service still sells many accessories and components from older systems. You can buy this sub woofer for less than $100, which should easily beat any repair cost you'll face. It may even come with the satellite speakers. The part number is VSDT2000R-SPBOX .

NOTE: JVC Service has a free shipping coupon going on right now, so you'd want to use that: DZYZXFX49GYZZ81

Also remember that there's a standard connection between the head unit and OEM sub woofer, so you're free to use a non-JVC unit. I would try to find one with a comparable power rating. Of course, the only drawback is that it won't blend in with the unit... but then, the sub woofer is usually tucked away out of sight.

Problem w/shelf system stereo system!!!!!!!!1


You say that the fault lies in the sub-woofer speaker....

You will need to remove the back panel of the speaker box and make a visual examinatiojh of the contents there just may be an overload fuse there that you can replace your self...there may be a broken wire if the Sub-Woofer has been dropped...

There may be a capacitor or choke that has come loose from its mounting and in falling broken a wire,,,but please have a good look to see whats gone wrong inside the sub-woofer cabinet.

If you like you could take the backs of both the right and left
sub-woofer speaker boxes then visually compare the good one with the faulty one so you can see if there is any physical difference on the faulty one...if they both look the same then you willl need to do some testing with a multimeter set to Ohms to see where the break in continuity lies...just compare readings between the good one and the faulty one to find the fault..
