Stereo problem

[Glide77]

I've been putting my stereo on the back burner, but it's now time to fix the problem. When I first bought my 92 fj80. It had a aftermarket stereo that wasn't working. So I simply changed out the fuse and it started working. Minutes later out on the road it happen again. I pulled out the stereo and noticed the oem wires been chopped and redone horribly. So I ended up buying a wiring harness to clean up the job. Everything was working fine for a while until I drove about 10 miles and the fuse popped again. So I was checking the speakers to see if there's any bare wires and noticed the speaker by the trunk is blown. Can that speaker cause a short?

I doubt the speaker is taking out the main fuse. More likely a wire is shorting to ground. Are all of the speaker wires OE?

Is the amp still plugged in ? If so it can blow the fuse, should be unplugged and be running off head deck

There is an amp on the passenger side to the right of the glove box unplug it see if the short goes away. Water could be dripping on the amp. Or you could do what I did and install a 500w marine amp with blue tooth and forget the whole deck all together.

indeed OEM amp if it still "plugged in" - regardless of the fact a aftermarket h/u is connected via the metra harness
can cause major "shorts"

would also advise - unplugging the rear sub amplifier too...(tis a worthless paper cone - likely disintegrating anyways)

ok, correct me if I am wrong.....but doesn't the 80 have a second set of plugs that bypass the amp? that's what all the stuff I read back in 2003 when I bought my rig indicated, to use the metra harness that didn't connect to the back of the stock rig, but use the "other" two plugs

"metra" plugs are on the left.... the OEM h/u plug is on the right.

trouble is - even though the are 2 distinct radio "plugs" - the OEM amp still gets 12v power - somehow -
and thusly send "signal" to the speakers - which I believe is what causes shorting -
again - best plan of action - simply unplug the OEM amp too...
