Radio doesn't work blew a fuse - 2005 Toyota ECHO

Hi if there is powerr to the radio then it must be the radio thats at fault.

did you check the fuse at the back of the radio when fuse blew ?

It has spark and fuel when the fuse is blown too?

should have gone with a plug and play connector

replace the radio it blew the internal amplifier

there are 3 power sources to radio. if stock, if not stock more.
Radio power.
memory power
and dial lamp power. (dimmer)

why not use a voltmeter to find out why its dead.
even better the FSM shows the wires, the colors and the path.
making guessing go to zero.

when working electrics pull battery minus lug, like the FSM directs you.
and keys in pocket. causing load dumps can cause very expensive
electronics to fail. even the EFI, PCM.

On the back side of the lighter there is a fusable link between the incoming power wire and the metal tab that connects power to the lighter. This is a very small wire, bent 90 degrees, between two tabs that are mounted on the same small screw. It looks like the incoming power tab and the power to the lighter would be connected, but they are insulated from each other on the screw. If the fusable link is blown, you will have power at the power connector on the back of the lighter, but no power to the center terminal inside the lighter.

the fuse for the radio is under the hood next to the battery

a bad fuse ...keep looking .....otherwise the main acc power/ or ground to all those dash areas has been cut or compromised...retrace your steps backwards

replace the blow fuse
above left knee, fuse panel there.
1 is blown.
your amp was shorted, it blew and took out what oem wiring they hacked into .

bad installation.
