My head unit worked fine untill i plugged into the rca jacks for my subwoofers. now all the buttons work and the head unit shows its playing noise but nothing comes out. Even with the rca jacks taken back out there is still no sound. Did i blow a fuse or short something out?

Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.
a. buy or make a audio plug the same as your external speakers one end is a headphone jack the other is rca's then get a head unit like a surround sound system tie into it and your set or you can do it the way i did same cord from head phone to rca but throw in a car battery a charger and an amp.
the circuit board and amplifacation supply inside the sub are blow or shorted out.thus preventing any sound. the head phone jack works only because it is a bypass feature supported by the actual computer not the surround sound unit
I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!
Please check your model number, I can not find it on the JVC service website.
This is a powered sub-woofer I think. You need to have a thick black cord that connects the sub to the head unit. Then the satellite speakers get connected to the speaker jacks on the sub-woofer box. The sub-woofer should also be plugged into an A/C outlet on the wall.
The speaker outputs are labeled right there where you connect the speaker wires. You should see a red and black connector for each speaker and they are labeled "front right" "front left" "center" "rear right" "rear left".
If you do not have the thick black cord you need to connect the head unit with the sub-woofer, you can not use this system.
If you look at the head unit and give me the model number on it, I may be able to find the part you need. But I must have a good model number to work with, preferably from the head unit.
Actually. I don't think you have to wire a remote switch from the radio to the amp on this product. This powered subwoofer supposedly has automatic signal sensing turn-on circuitry. I have the same problem. So I think I'll try to just hook up the power (to the battery), ground and the + / - speaker wires to one of the back speakers in the car and see if that works.
This sounds like a signal problem. Make sure that all of your signal cables are plugged in fully. If all are, you need to check for coninuity between the shield ground of the head unit's RCA jacks and the case of the head unit. With no RCAs plugged into the head unit, you should read ~0 ohms between the shield of the RCA jacks and the case of the head unit.
