Eh all,

2007 Accord here , replaced radio head unit as well as all speakers with aftermarket ones.

Everything worked fine for a few hours , then next morning no sound coming out of all the spaekers.

Checked all the fuses in behind driver kick panel and under the hood. All checked fine.

Also checked all the wiring to the speakers to make sure no wired were cut or damaged, but again nothing.

Aftermarket head unit works fine.

Any ideas as to why this is happening.

Thanks

 

When ALL speakers suddenly no longer work, it seems to point to the head unit as the likely problem (plug connector fell out or head unit amplifier failure). What do you mean when you say, "head unit works fine"? New electronics will either fail shortly after being put in service (infant mortality), or they will operate fine for a long time.

 

Aftermarket head unit display works just fine, except no sound.
I tried putting back OE head unit with just one OE speaker but can’t get any sound as well.

Does the OE head unit ( which btw is a basic one) have some sort of amp hidden under the console ?
Or is it built in the head unit ?

I find that weird that 2 head units stopped working after just replacing the speakers ?
