Well I may have a bad factory amp.. ?

nujeepguy

could be, now youre on track!
some spk work?

JPXJMOAB

The front speakers work, if that's what you're asking?

nujeepguy

yeah. do we all have amps? im new at jeeps, been working with elex for 60 yrs!!
usually if some spk work the amp is ok

check the rear spk themselves with ohmmeter. should hear scratching as you touch connectors and read appx 4-8 ohms

wher is amp??

JPXJMOAB

Not all have amps, however they're under the rear seat. I'll check the speakers themselves tomorrow .. I don't see them being an issue being they worked the other day..

nujeepguy

ok, later, good luck

JPXJMOAB

Well the speakers work, tested them in another vehicle.

JPXJMOAB

Using my meter, the drivers side rear speaker has 12.6V going between the 2 wires.. the passenger side showed 5.9V going between the two wires.. seem normal? I'm not sure, not much of an audio guy. I'm leaning towards a possible amp failure for the rear speaker output?

nujeepguy

12v dc? with spk? if so spk is burned out. should not have dc volts across spk.

did you or others ever ground the speakers? they need to be floating no ground as in the svc man

JPXJMOAB

I took the speakers out and used a multimeter between the two wires wit the radio on, speakers ohmed out good..

JPXJMOAB

Guess I don't understand why one speaker wiring would have 12V and the pass side only has 6V? Audio wiring doesn't make sense to me LOL

nujeepguy

12v, 6v, could be from bad transistors in amp

if speakers AND wireing are good you can try a new amp.
be sure no spk wires are grounded.

JPXJMOAB

Ok, I'll have to check wiring.. but if they're getting power isn't that a self test that wiring is ok?

nujeepguy

? if speakers and wires ore ok it sounds like the amp. be sure no wires are grounded or you could blow a new amp.
unhook wires from amp. see that the're not grounded and have no voltage on them.
thats all i have.

Thanks, will do. I found a used factory amp on eBay for $28
