I recently purchased an aftermarket radio to put in the car.
Bought a kenwood kdc-mp345u, an amplifier and a 1200 wat 12 inch sub

my friend helped me install it, as i dont know as much about sound systems as he does.
after removing the old radio, and connecting the wires for the new one, my friend found out that Hyundai has their own color codes for the wires, and we had to redo them.

during install, there was a spark from the wiring for the radio, as we were testing out what wire configuration works out. im guessing a speaker wire made contact with a speaker wire. we blew a fuse, but i replaced that fuse, and the problems that im about to list, are still existent.

after the job was done, the car sounds AMAZING, but there are some faults to the installation.
my keyfob doesnt do anything anymore,
interior lights dont turn on. (bulbs were replaced, so thats not the problem)
dashboard clock doesnt work
gauges are weird, (when engine is started, the speedometer jumps to 70 mph, then back to 0. tachometer jumps to about 4500 rpm, and then back down to 1000 rpm.

we are going to re-look at the wiring and see if that is the problem.
has anyone installed an aftermarket stereo for their car? results?

thank you very much!
Matt

speaker wires dont spark... wire with source voltage to ground sparks and pops fuse..

Use DVOM and inspect all the fuses for power on each leg of fuse..

There is 1 fuse not called out that you will find source volt on 1 leg, and "0" on other leg..

i just decided to redo the wiring myself, and i was very successful.
also had found the fuse port was messed up, and the fuse was not making connection where it needed to.

now the car is bumping!

Hi doggxyo,

I had the same problem last night installing an aftermarket radio. One of the cables made contact with the back of the radio and I saw a spark.

The interior lights are out and the radio does not power on. I see also the same behavior you described with the gauges.

What fuse did you replaced? Was it in the fuse box under the hood or somewhere else? I was looking for a blown fuse but didn't see any.

Is there a fuse for the radio as well?

Any help it's appreciated.

Just use a DVOM on all the fuses... the fuse that has power on 1 leg and "0" on other leg is open circuit, replace it. Keep going till you have verified all fuse are good.
