The problem is everytime i turn my head lights on the pyle swiches to a blue screen, the radio goes off and it has the words "car" in the top left corner of the blue screen. i own a 2004 ford explorer..

You have the unit wired wrong. When you shut your key off the radio loses ALL power and it needs ACC power to maintain the memory. If not, the unit will reset itself. The screen you see is the touchscreen calibration screen. Just follow the " X " around the screen to 5. Then the unit will boot up again. You will have to reset radio stations and EQ and speaker settings. If you don't fix the ACC wire, you will have to do this A LOT!

Sounds like he did not wire a remote line from your radio to the amplifier, if he put a 12v from the battery to the amp and the remote spot on the amp then it will not turn off, you will need to either wore a toggle switch to the remote so you can turn it off manually or check the back of your radio for a remote line or splice a remote line from the accessory power supply on your radio so the amp will turn on when the radio is on

Please send me more details

Fault is in your sony. The fuse blows because of high power consumption. I think the final audio amplifier are burned( maybe only one channel)

Yes, you wire the head unit wrong, there is ground, batt12v constant(usually yellow) Constant because you radio memory, Accessory wire when the key is on(that way your radio turns on and off with the keys, and last but not least you ILLUMINATION WIRE witch when you turn your headlights gives you curren 12v...
ground
Batt 12v
Accessory (on with the key on number 2 position)12v
ILLUMINATION. 12v when lights are turn on

u probably connected ur power or constant to ur lights. if ur lights turn on ur accesry switch and than ur ight if ur stereo turns off thanu have tosee witch wire is connected wrong

It may be a voltage problem. check to see if you are getting the proper voltage. if not try using a toggle swich on the e-brake wire.

get another one

bad head unit or look at your ground wire good luck

CHECK TO MAKE SURE THE INLINE FUSES ON RADIO ARENT BLOWN .

YOU CAN CONNECT POWER TO THE POWER OUT LEAD AND MAKE IT COME ON
