Re: car radio
Need more info such as car year and model, what brand of aftermarket stereo
etc. How did you hook it up? Did you use the factory wiring harness in the
dash by purchasing an OEM harness that wires up to your new stereo, or did
you snip off the harness and try to wire everything individually? The OEM
harness is the way to go because they all include instructions on how to
wire it up to the stereo, and then it is just a matter of plugging it into
the existing harness. It also lets you remove the aftermarket stereo and
reinstall the factory if you decide to sell the car.
You said you checked the fuse, I'm assuming you meant the one for the car in
the fuse box. Look around on the back of the aftermarket stereo for another
fuse. Most have a mini or spade fuse near where the wiring harness goes
into the radio itself, or some have two round type fuse holders in the
battery and ignition hook up wires. Be aware, that if you are blowing a
fuse, there is a reason, so you should double-check your wiring.
If your radio suddenly died after a song with high bass played, you either
had it turned up way too loud and blew all of the factory speakers (highly
unlikely, but it has happened), or the speaker output (watts in RMS) is too
much for the factory speakers. The other possibility, depending on the car,
is that there is a factory amplifier that is not compatible with your
stereo. Most new head units come pre-amplified by at least 40w x 4
channels, some as high as 60w x 4, these units have plenty of power on their
own. If the signal coming from the speaker out on the stereo is being
re-amplified again, this may be too much power for the factory speakers.
Sometimes turning off the Loudness control can remedy this, because you
would definitely notice the sound would not be very clear if you were trying
to power 15-30watt factory speakers with 60watts (more if there is a factory
amplifier) from the source unit.
First give us some more information and we may be able to help further.
