verify your amps input. hook up a portable cd player with a headphone to rca "y" adapter to the amp and try that, to make sure it isnt an issue with the reciever/cd deck oir the input circuit. if the amp works correctly with the protable cd player/ walkman.mp3 player whatever, instead of the car deck, then something is wrong with your decks audio output. if it does not work with a secondary input device then perhaps you have the power hooked wrong. there should be both a red and yellow power lead from the amp, the red should be connected directly to the battery, and the yellow to the "acc on" (any circuit that turns on only when the car or stereo is turned on, sometimes connected directly to the stereo). both can be connected directly to the battery, but the yellow would need a switch, in that case, to turn the amp off when not in use.
Yes, if your car speakers are ran through that amplifier that red wire (power wire) needs to be connected to the battery. I would make sure that there is a brand new, or clean terminal to connect to the battery. I usually use a ring terminal on the end of the power wire to connect to the positive battery post bolt. If you do not have a ring terminal on the end, you do not need one, but I do it for the fact that it is a cleaner installation and a certanty that it will not fall off the positive post. If you have any questions feel free to email me at [email protected] put subject vet amp no sound.
well u run a power wire atleast 4 guage from the positive terminal on the battery, then 4 guage to a chasis ground source, then a remote wire to the rear of your cd player that will kick the amp on when the cd player turns on... then for subwoofer wiring go to www.the12volt.com for sub wiring options... you need either single voice coil 4 ohm subs or 2 ohm dual voice coil subs to get the 2 ohm load to the amp so u can get the rated power out of it...
The only wires that should be going to the subs are the Speaker wire, The power, goes to the amp, Blue the remote wire should only go to the remote spot on the amp wich is usually labeled rem. and the ground all goes to the amp.
You will need the amp wires. Red Positive to battery, Black negative from amp ground to unpainted car body surface, and the blue remote wire that goes from amp to remote wire on back of cd deck. Then you will need the rca cables from rear output of cd player to the amp. Then just the positive and negative wire from speaker to amp. Use Speaker Positive wire to Amp Right Channel Positive And speaker negative wire to amp Left Channel Legative wire. That is it.
If your radio is still working, then your power is OK. The Sony CD changer gets its power from the Sony Unilink cable. It is possible that it passed a power spike down to your CD player while hooking up your battery cables.
I just had a CDX-757MX just die a few days ago myself. My radio, amps, and other changers are still working. Could be an unfortunate coincidence.
Check the head unit settings.
They have probably been reset.
If it has a subwoofer setting make sure it is on.
Failing that, disconnect the subs completely from the amp and put a "test" speaker on the terminals to see if the amp has output.
