I have a 2011 Jeep Liberty has the infinity amp in it I put aftermarket radio in it and no sound at all

fuses are blown
if the radio has 12vdc to all power pins, then it has power.
if grounded too.
if dead in all modes!now, the head is dead (AMP dead at least)
im assuming at least 4 speakers and not all 4 can magically die one day. (never seen in 50 years of electronics that case)

get a volt meter, and learn to use it?
the meter is $10 at walfart. 12vdc is good. 0v is bad.

the head and amp has a manual.
most modern head the Red wire is radio power.
so is the radio part dead. dial dead, cant scan FM,or AM.
if totally dead radio side, no sign of ANY life. (not just sound)
that is a bad fuse.
if the radio is scanning, then the amp sides is dead.
check the power to the amp side.
is amp separate> you never said if its a all in one radio or 2 parts.

1999 Toyota Avalon. I've dealt with only one speaker working in the back seat passenger side of door and now it went out and the smell of burnt wires? Permeated through the car. What's an easy, cheap fix...

Hi, as a retired radio installer here is what I reccomend. First, you should the head unit. They are very cheap now. Wallmart can fix you up for under "a c note". Pick up a pair of 5x7 speakers for the rear. Most of your toyota systems are using sep. Amps. All.told, including labor you should be under $200. That should give you many happy miles.

if the fuse has not blown it could be the ignition control module it controls the dash and a few other things.

My radio stopped working

Could be speaker fuse or fuses esp if played loud with bass turned up worst case is power transistors blown then you may as well scrap it considering cost of repair vs second hand radio. Look at wires coming out of back of radio to speakers for inline fuse holders push and twist to open.There could be a fuse in rear panel of radio. Sorry I can't tell you how to remove the radio

Rear speakers stopped working in 2004 chevrolet trailblazer

This could be caused by many things. Generally, if they just stop working altogether (without being abused) it's a failure in the internal amplifier in the radio (head unit) itself. Other possibilities include:

1.) Blown speakers due to abuse
2.) Faulty wiring

You can test for a blown speaker by using a multimeter to measure the resistance in each speaker. Unhook them and put the contacts on the terminals. They should read at or near 4 ohms of resistance. If it is 0 or near 0, they are blown. Ask your kids if they turned daddy's radio up loud when he goes into the store ;)

Radio powers up but no sound

start with main fuse panel, looking for a blown one, unlikely to be blown speakers unless you play real loud!!
