1993 Maxima Radio Replacement

#11

In the 1994 Maxima, I brought the Alpine head unit ground wire to one of
the screws that holds the original radio bracket in place, thus
grounding it.

My Bose radio died a few years ago and I'm just getting around to
replacing it with a radio / cd player / mp3 player that I bought at
Wal-Mart this morning, Virtual Reality Sound VR3 CD Player.

I bought the wiring adaptor and the converter for speaker level to line
level and hooked everything up. But the radio won't come on. I know
there's switched power since I can turn on the amps and I can play
music via my mp3 player directly.

I'm thinking that the problem might be with the ground. My questions
are:

1 - Will the lack of ground prevent the radio from powering up?
2 - If I need to find a ground where's the best place? I tried
connecting to the screw that held the old radio in place and the
outside of the cigarette lighter.

Any help would be GREATLY appreciated.

Thanks,
Joe

I tried JimV's suggestion and connected the radio directly to the
battery and it came on.

I knew there was power on the switched wire but I never checked for
power on the constant 12v. I connected the switched power wire to both
switched and constant leads on the radio and again it came one.

So it looks like the constant power wire is dead. Does anyone know
where I can tap into constant power on any of the other wires in the
radio area?

THANKS again for everybody's help.

Cigarette lighter would work.

Maybe your original radio did not die. Have you checked the fuses to
see why the constant power wire is dead?

My original Bose radio was corroded and not fixable.

I checked the fuses yesterday but not today.

If I use the cigarette lighter does anyone know which wire would have
the power?

Thanks again,

FINAL QUESTION

I found the power wire in the cigarette lighter. Not too hard since
there are only 2 wires.
:-)

Can I just cut and splice in a new wire to go to the radio? Do I have
to disconnect the negative connector on the battery or just cut the
wire.

Thanks,
Joe

It would be safer to remove the negative cable first. You had the Bose
system? Did you get an adapter that was made for that? Are you planning
to use the factory speakers? It might not work.

Yes I got the converter from speaker level to line level at Wal-Mart
and got the wiring adaptor from Crutchfield. I tested it out using the
output of an MP3 player after connecting the amp wire to the switched
wire. Sound came out great!

Looks like I spoke too soon.

Looks like the cigarette power is switched.

Can anyone please point in the right direction to find constant power?

Thanks again,
Joe

Thanks. I have a good ground now. But I need to find a wire somewhere
under the dash that has constant 12v+ so I don't have to run a wire off
the battery.

If I use the switched 12v+ I lose all my settings on the radio.

Note that some stupid CD players consume up to 0.14A in sleep mode. That means dead batt if parked for weeks... (Two pwr supply wires, one for mem settings, one run-pwr via ign key ...is one indication. Manuals were ashamed of warning about pwr consumption.)

Ol radio was connected directly, no need for key to get player on. My new USB player one cannot be, or batt will die: to listen, always ign key has to be turned.

Good ground is also found on the surroundin dash metal structure.
