Question about JVC MX-G50 CD Shelf System

1 Answer

Subwoofers unresponsive I was listening to some heavy-bass music the other day when my subs stopped working all of a sudden. Since then, there has been no improvement. The speakers still produce sound and the speakers and woofers work with other receivers. Is it possible that the part of this receiver that send the bass signal to the woofers has burnt out? If so, how can I fix it? Thanks! Steve

Check the physical condition of subwoofer to make sure that the surround has not rotted out or been blown away. If ok, then using an ohm meter check for the nominal speaker voice coil resistance to make sure it is within spec. If both of these areas are good then you have destroyed the output stages of the amp(s) driving them. Every 3 db of bass boost doubles the output power. So if you are blasting along at 100 watts and you jack up bass by just 3 db the amp now has to put out 200 at those lower frequencies; go up by just 6 db and you are now talking 400 watts! And what does that do to an amp when you over drive it? You guessed it!

SOURCE: WOOFER NOT WORKING JVC th-m606

I'm having the same problem. It seems that the mosfet's shorted blew up a capacitor and took some surface mount parts with it. It will be the middle board with the metal shroud (shield). The mosfets are almost impossible to find, I have replaced them (as well as other parts) but still have yet to find the problem. I'm now trying to find the subwoofer amp board (part#LVA10505).

SOURCE: Connecting Powered Subwoofer to a Receiver

you will need a line-level converter to use this subwoofer- it is a rectangular-shaped box with wires coming out on one end and red-and-white RCA plugs one the other. The end with the wires coming out will hook to the receiver, and the other end will need to plug into the sub.

SOURCE: I have a TH-C5 JVC receiver that is dead.

Its all going to be proprietary to the jvc system. Unfortunatly you will only be able to use the speakers with another reciever.

WHAT SIZE AND TYPE BOX DO I USE FOR ONE PIONEER TS-W304C SUBWOOFER


You have a lot of choices for this. First, unless you are tuning the sub to a specific frequency you have options. You didn't specify the size of sub so it's difficult to say specifically, but if it's a 12 inch sub, you need about 1.5 to 2 cubic feet. Of course the performance of the sub depends on the music you listen to. If you listen to rock, pop, classical, or country, I recommend a sealed box. A sealed box gives you better control over your sub. The air acts as a cusion and decreases the return time of the cone to rest position. This gives you tighter bass. If you listen to rap or hip hop, I recommend a ported enclosure. This type of enclosure allows for more cone excursion, thus allowing the sub to recreate lower frequencies. Hope this helps.

My brand new Kappa One amp is powering 2 brand new Kappa 100.9w subs at a 2 ohm load. The Ground an Power are both 4 gauge wire. The problem is my amp is just getting so hot that I can only touch it for a...


Sometimes these amps have been known to get hot very easily. That said, I would first confirm the resistance on your speakers at rest is 4 ohms each, so that your amp is seeing a 2 ohm load. Be sure that the smart switch on each sub is flipped to the 4 ohm mode, and measure each separately.
Be sure that you've properly set the filters, gain, and bass boost so that your amp is not being over driven. Your HP filter should be set no lower than 20Hz--most music is never going to go that low so there is no point. A narrower frequency band is always going to be healthier for your subwoofer. The LP filter should be set no higher than 90 to 100 Hz at the most, depending on how much midbass your speakers can handle, so that you don't have too much of a sonic gap between the subs and mids. As for the gain, a good place to start is with your radio set at it's highest comfortable, distortion free setting, minus 25%, then start with the amp's bass boost all the way down, and the gain set to the minimum level at which you can just begin to hear music. Choose a bass heavy track if you ever listen to bass heavy music, so we can prepare for the most stress that the amp will experience. Slowly turn up the gain until you start to hear distortion during heavy bass hits, and back off 20% - 25%. This should be the highest volume you ever push your amp to, and from here, you can ever so slightly turn up the bass boost if you absolutely must, but not to the point of any distortion, if you hear any, back it off a bit.

My jamo sub 200 & pioneer vsx517 receiver is not working properly


What do you mean that it sometimes doesn't work? It doesn't power on automatically?
Check settings of your receiver - if it has subwoofer output enables and if low frequencies from all channels are directed also to the SUB. By default only the LFE channel (.1) of 5.1 signal input is fed to the subwoofer. So Sub will work in this case only when you listen to 5.1 signal (DVD movie for example), but for radio or stereo music, only front speakers are used. By configuring this bass redirect, you can use subwoofer for all signal types.

Music is coming through my sub as well as bass


your amp might have a low pass filter and a high pass filter make sure it is switched to low pass and that should prevent music from coming out of the subs and just alow the bass too

Sub keeps loosin bass


Its probably not your subwoofer- its likely that your amp is showing its age after 2 years of bumping -But it could be that you have partially roasted the coil on the sub which is tripping your amp into protect mode-thus shutting down throw a different sub in there for a week and listen to it and if it stops acting up then its probably the sub if it still shuts down then it may be time for a new amp

Subwoofers and amps


If you replace the head unit, that will make a big difference. If not, then it really depends on the type of music you primarily listen to. From a single sub setup, an 8 or 10 in a sealed box is best for punchy base, i.e. alternative, hard rock... A 12, 15, or 18 is designed to reach those lower bass frequencies and are suited better for ported enclosures. I.e. Rap, bass heavy Regge, etc...However, that's not to say that you can't go back and forth between them. The main difference is that a 10 and below tends to be more accurate, and can follow the kick drums, for example, a lot faster than larger woofers. Determine what your primary listening music is, what you want out of your system, and a maximum price for everything first. Then, I can suggest woofers, amps, etc.

Subwoofer works at high volume, doesnt work at low volume


You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.
