Hello. I am to the most maximum point of being frustrated with this. I have looked all over the web and found no solution that worked.

I have a '97 Dodge Ram 1500 Laramie with the Infinity speaker system. I bought a wire harness from Wal-mart and went to work. I matched all the wires together fine, but I did notice one thing. I had an extra plain blue wire that didn't match that said "power antenna" which I don't have, so I taped it off. I also have another wire that didn't match the aftermarket stereo's harness, it was a plain orange one labeled "dash illumination". Either way, the new stereo powered up fine. ONE problem: one speaker works and the rest are all scratchy.

Now, I had this same exact head unit in the truck before, and it worked perfect. I swapped it out with my girlfriend's car and went back to stock for awhile. Now, she has a new head unit and I went to put this one back in, and I run into this problem.

Also, I tried taking that plain blue wire and splicing it to the blue/white wire on the aftermarket's harness, still nothing. I know that the Infinity system has an internal amp for each speaker, so I know this is the issue.

No, the speakers aren't blown, I thought I messed them up at first, but the stock stereo runs them perfectly fine.

HELLLLP!

 

Sorry for the double post, but I just remembered something. I bought the right wire harness (it said 94-01 Dodge Ram), but it said nothing about Infinity. I think the one I bought before said Infinity on the back.

Could the wrong harness be the issue? I'm at a dead end here.

 

The infinity system has external amps on each speaker. Its throwing me off that one works and the others are scratchy.

 

Yeah, that's why I'm so frustrated. I posted in two different areas on this board and no one has replied.

I'm thinking I may have the wrong harness, because it didn't say anything about the Infinity system on back, just had the right make/model.

Still searching Google for it.

 

to narrow ur frustrations, when i was doin my radio, i was told if i did have the infinity system, that i could just cut the wires for the amps and the speakers would work just fine. i dont have the infinity system but its worth a shot just to see if thats the problem. if its not, just reconnect the wires and ur back at square one

 

you need to connect that blue wire you taped off to the amp wire on the stereo. all will be well afterwards.

 

Trying to run an amplified signal and then amplifying it again can't sound good lol.

 

the amp signal wire has to be hooked up to the harness for everything to work. been there, done that. took me 2 weeks to figure that out when i first got my truck.

 

redneck_ram is correct. The amp wire he refers to is just a trigger to turn on the infinity door amps, and just needs to be connected to a switched 12v source. Your new head unit's power antenna wire will provide the switched 12v.

 

DO NOt use the power antenna wire there should be a blue/white wire for the amp that is constant power when the radio is on

the power antenna wire will only power the amps when on am/fm because it is ment to raise or lower the antenna only on am/fm when on cd,usb,aux it will turn the amps off due to the antenna is soposed to be in the down position
