Check the wiring at the speakers themselves. It's possible that while you were moving the box one of the speaker wires came loose and shorted against the other terminal. A shorted speaker wire or damaged speaker will cause the amplifier to go into protect mode. If you have a digital multimeter with a resistance feature, you can test the resistance between the positive and negative terminals for each speaker.

Any of the line output converters on this link should do the trick.

You can not connect the speaker lines directly to the RCA inputs of your amplifier. But you can connect them to your amplifier if your amp has a high level input. Most of the time it looks just like the speaker jacks of the amp, but smaller. It will be labeled high level input or speaker input. Sometimes an amplifier will have a jack for a wiring harness just for this purpose. Some amplifiers have them and some don't.

If your amplifier does not have them, you can purchase a line level adapter at most anyplace that installs car stereos. it converts the speaker level to the proper level of the RCA input.
Just follow the instructions on how to connect it.

If you try to connect the speaker outputs directly to the RCA input of the amplifier you will blow up the pre-amp in your amplifier.

I hope this was helpful to you, if so a good rating is always appreciated.

Thanks and let me know if you need more help.

SOURCE: distortion

One word, No.

Distortion comes from the audio signal being clipped by one of your elements in the system.

What I would do first is measure the output of the radio with an oscilloscope to see if the signal is good. If it is then I would determine if the source of the distortion is the amplifiers or the speakers.

If it is the radio have that fixed or changed, If it it not, it might be a case of the radio overdriving the Amps causing them to clip the signal peaks. check for the max signal input of the amps and make sure the system is adjusted for that.

Let me know how this turns out.

Thank you,

SOURCE: my radio stopped working after hooking up the amplifier

Did you double check your work? Did you check the resistance of the fuses? Just because the fuse appears to be good, it can still be blown. Do you have access to a multimeter? You need to check and see if the head unit is receiving 12 Volts continuous which you put the multimeter probes to the black wire and the yellow wire. Then connect the probes to the black wire and the red wire. This wire should only have power when the car is cut on. If you are not getting 12 volts to these points, the problem is your wiring system somewhere...probably a fuse. If you are getting 12 volts, your head unit is garbage. I want to say it is the fuse.

Installed a Sony Xplode into a 99 Blazer and everything on the radio works but will not play through the speakers


The Bose system is complex - it has an amplifier separate from the Bose compatible radio. This amplifier takes low level audio signals from the radio, not full driver outputs from a replacement radio, and by trying to use the replacement radio you may have blown the amplifier. If that is the case, you may not be able to go back to the original radio.
The only option you may have with the replacement will be to find the Bose amplifier and bypass the connections to feed the replacement radio outputs directly to the speakers. This may not be as simple as it sounds, as distribution to the various speakers comes from the amplifier, not the radio, and the wiring from the amplifier to the radio may not have all the wires you need. Before going on, you had better get a wiring diagram for the Bose system (service manual or Alldatadiy.com).

You must have gotten the power lines mixed up. You need to connect the power to the amp and radio the the switched side of the power supply. Or, you connected the amp power and the amp switch wire, usually the blue wire in reverse.

Sounds like an amplifier issue. Check the fuses that run the factory amplifier, if not a fuse, then most likely a bad amp.

Amp playing speakers very quietly


it sounds like you have the polarity of the speakers hooked up wrong on one of them, try unhooking the new speakers you added and hook them back up one by one, when the music gets fuzzy then reverse the wires for that speaker, this should cure your problem.

Radio comes on but i cant hear any music


You may be connecting this stereo into an amplified system. If the original factory stereo worked with the factory amplifier, your stereo is not turning the amplifier on. If you purchased the aftermarket wire harness that mates to the factory stereo connector, hook up the "Amplifier Trigger" wire, this wire is usually blue.

No sound


It's very likely that you have a factory amplifier in the vehicle that needs to be either turned on or (preferably) bypassed to get sound to the speakers. If your vehicle is a Mustang, it's almost certain that you have a factory amp. If the factory plug includes a long, 8-pin gray plug and a small, square 8-pin plug connected to a round cable, then the amp turn-on wire is at the opposite end of the gray plug from the constant power wire. This needs to be connected to the blue/white wire on the Sony head unit for the factory amp to turn on. Otherwise, if you dig into the radio cavity a little bit, you'll find a black 8-pin connector that looks very similar to the gray connector at the back of the radio. The black connector pins are connected directly to the speakers, bypassing the factory amp.

Pavit won't play


You have to reset it back to factory settings because you deleted with the original demo music some files needed to start the built-in player. So do the factory reset after you restart your Pavit MP3 Player. Then copy you music and play them.
