Re: Changed battery cable now radio will not even come...
When you said inline fuse I get the idea that this is not the original radio. Do you have power on the inline fuse? The 50 amp fuse you checked is a bit much for a radio. There may be a smaller fuse in another fuse area of what car type you have. If you do not have power at the inline fuse find some where you do have power (12vdc) and connect to it. If you have power at the in line fuse check the ground wire. If you have a test light or someway of checking for power test all fuses everywhere. If you have a fuse location guide for this vehicle look for the fuse for radio. If it was a add on or after market radio they probably caught power from the original source That is fused under the dash.

there should be an inline fuse that is on the back of the radio. i know I would hate to do this too but I would take the radio out check the fuse on the back of the radio along with the inline fuse in the cables. Also you need to check your connections mainly your power cables. Make sure that they are not touching ground and make sure that all of your wires are reinforced with electrical tape.

If your radio is the pioneer model stated, it definately has a fuse!
The little black box on the yellow wire contains a fuse.
If there is no black box on the conctant power, you may have damaged the radio with a voltage spike(s) when connecting the battery posts.
I am sure that the radio fuse was checked to see if power is actually going to the radio? The next thing to check is the multipin plug on the back of the radio. If it was removed sometimes the pins get bent when plugged back in. Make sure all pins are clean and straight. Try to disconnect wires that were changed to install the amp and put everything back to original and see if the radio works. The amp should have a direct connection to the battery with its on fuse correct? Depending on the amp if new or used may have internal problems and will have to be sent back to the manufacturer for repair. Hopefully when the wiring is put back to normal in the vehicle the radio should work, unless the amp load has damaged the output transistors to the original radio. Good luck.
The unit will have 2 fuses, or at least a second power supply that is generally connected to continuous power, best bet is straight from the +ve batt terminal. If this power supply has been disconnected or has a blown fuse, then you will also loose memory functions from you radio.
Check first under the bonnet for a memory backup fuse holder that has generally less than 1 amp fuse,
no luck, then about the rear of your fuse box for a fuse holder,
or worst, behind the unit up under the dash. The wire from the back of the stereo on Sonys is generally the RED one for memory backup
restoring this power supply to your stereo will then allow for all your presets to be retained in memory
Good luck, happy to talk to you more about the problem, a "FixYa" rating will help my profile
YOU CHECK THE CAR FUSE...BUT THE STEREO HAVE ANOTHER FUSE. CHECK IT IF PROBLEM PERSIST.... I´M SORRY BUT I THINK YOU BLOWIT ,YOU MUST GO TO REPAIRED
SOME TIMES BLOW A THIN LINES INSIDE THE STEREO AND REPAIRED THOSE WORK AGAIN AND POWER AMP IN THE STEREO BLOW TOO.
you are taked the wrong cable to turn on your amp......alpines have a two blue cables one of theme start the power amplifier and the other one start the electric antenna when you turn the radio,if youre earing the cd or tape and change to the radio this cable have 12 volts to startup the antenna.....solution .....just try change the other blue cable.
