hook power wire to positive side of baterry then to amp power fuse needs to be no more than 18 inches from battery fuse size differs due to wire size ground wire needs to be same size as power wire p.s. hook up ground & power wire before installing fuse hope i was helpful

That subwoofer is included in the MHC-GX450 system. I have the amp/CD/radio unit. but not the subwoofer. The control cable connects the LED on the Sub to the main unit. When the main unit detects this connection to the LED it switches on its internal subwoofer amp to drive the subwoofer.

Does the JVC receiver use a "control" circuit through its external subwoofer unit to signal that it is connected to the subwoofer? If not, you do not need to use the control jack on the SS-WG450 to connect to the JVC receiver. Connecting the Sony subwoofer to a subwoofer output on the JVC unit may be enough. Do check the impedance required by your JVC receiver. Sony lists the SS-WG450 as having a Nominal impedance of 6 Ohms. Is this high enough for the JVC unit?

That would require you to disassemble the subwoofer cabinet and disconnect the the supplied amplifier.
Connecting this unit to a different amplifier would provide no benefit to you unless the on-board amplifier became damaged.

There are usually fuses in appliances like that but I don"t know if they are even change able so I would say it would be a better idea to get a new one, just save a little time and hassle.

take a digital volt meter and check the power cable and ground on the amp to see if you are getting any power . should read 12.5 or more if no power then check fuses and the ground connection

if you have power then replace the equipment that not working

Radio Shack?

Hello pmdharan, It sounds like the subwoofer is not turned ON. Go to MENU ITEM > SPEAKER SIZE >SW (subwoofer) and select ON. Hope this helps.

you need to find out what size speakers you have now and upgrade them with that size the amp you get will be based on the rms rating of the speaker. Example if the speakers rms rating is 100 watts the get a amp that puts out between 100 and 120 watts rms also to add bass you could go with a subwoofer that will add all your low freq. If you want something that doesn't take up alot of room try a bass tube you can get one amplifed or not.

Good Luck

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.
