I've search the electronical & sound systems forum and have found plenty of information regarding the Nitro amp and installation of after-market speakers, but little information regarding other amps, especially detailed information regarding the harnesses.

Is there a wiring harness adapter that would plug directly into the Jeep's amplifier wiring harness that is equipped with an Infiniti sound system?

I would like to keep the head unit, but upgrade the amp and speakers. I would rather not cut any of the existing wiring and use the wiring and wire harnesses already in the Jeep. I am looking for a basic 5-channel amp (Alpine maybe), 2 component speakers for the front (tweeter & mid-bass), 2 coaxials for the soundbar and a subwoofer. I would like direct replacements with no cosmetic alterations.

I already know that the amplifier can probably be installed in the same location as the stock Infiniti amplifier, with little or no modifications, on the panel below the steering column. I am also aware that some coaxial speakers may require some trimming of the mounting holes/brackets in the soundbar. I'm not quite sure about the tweeters on the dash.... Hopefully I can find direct replacements and not have to cut or drill anything.

Any recommendations on amp, speaker and subwoofer choices are welcome.

Thanks.

 

The reason you don't see a harness for this is because you'll still only being drawing a line level. If you're dead set on keeping the stock HU, you're only real option is to tap into the line level and go from there. That's why most people upgrade the HU, so you don't have to do that.

Also, you should be able to fit quite a few speakers in there without trimming or maybe just a little trimming.

 

I realize that the output from the HU will be line level, but many amplifiers on the market have line level inputs. Otherwise, I've seen line level to RCA converters that are inexpensive and seem to work fairly well.

Is there at least a color-coded diagram of the plug feeding the amplifier identifying the cables? If I'm going to tap the cables, I would need to know which ones to tap.

Thanks.
