Hoping someone can help with this. I bought a new 2010 Maxima with the nav and Bose premium system about 2 & 1/2 years ago. I was not happy with the way the audio system sounded so I got Crutchfield to do a install about a month or so after buying the car. They left the factory headunit and Bose amp in the car and took the outputs of the Bose amp into a JL Audio Summing Interface and Clean Sweep, then on to an Alpine PDX-5 amp, then on to new speakers throughout the car. I was never exactly happy with the final product, but it was better than the Bose system from the factory.

Everything worked fine until about a month ago when I go in the car one day after lunch and there was no audio coming out (no radio, no iPod, no nav talking...just nothing coming out of the speakers). Everything had worked fine when I go out the car before lunch. I took it to a local audio guy and he did a quick trouble shooting on it to find that the Alpine amp and speakers worked fine, so we assumed that the headunit or Bose amp had gone bad. So then began fights with two dealerships on trying to diagnose the problem. Their tech played with it for 2 days, but eventually said that they couldn't figure out the problem and that Nissan techline had told them I had to return the car to stock condition before they would continue diagnosing.

So I took it to Crutchfield and they pretty quickly figured out that a fuse connector on the Clean Sweep had gone bad (fuse was fine, just the connector had lost connection). So they fixed that and the audio was back.

So here is my problem: The system sounds different than it did before. It seems like there is less stereo separation/width to what is coming out of the system (I am not exactly sure it is mono or a mix or both stereo channels into both sides, but it is messed up). Crutchfield didn't change anything. I am wondering if there is some setting that Nissan changed on the headunit or Bose amp that would do this. Anyone heard or know of this?

There reason I know this is possible is that my last car was an Audi A6 with the Bose premium system. I never mod-ed that system as it sounded awesome from the factory. But the CD player stopped working while it was still under warranty and Audi replaced the headunit. When I came to pick up my car, the sound imaging was all messed up. I went back to the dealership and the tech knew what was wrong. He did some key combinations on the headunit and was able to switch a setting from non-Bose to Bose system and everything sounded right. Apparently Audi used the same headunit for non-Bose and Bose options and you have to set the headunit for what is in the car in its software settings.

Anyone know if this is done in the 2010 Maxima?

Thanks!

 

I know in the 95-2003 maximas there were seperate head units used for bose vs non bose. I doubt that they would use the same unit in the past years the bose and non bose units used different circuit boards. It would make sense b/c It would save costs to use the same unit though. But if your unit is a 6CD unit(if all the new gen maxima bose units are 6CD) than i highly doubt that it would be the same unit used for non bose systems.

 

Are you using the outputs from the Bose amp as inputs for your cleansweep? And are you amplifying your door speakers and /or subs?

 

get rid of that clean sweep its garbage ur factory radio will a cleaner signal than a line level converter thats all that JL Audio is a fancy looking piece. are u getting ur signal through ur bose amp or did u disconnect it?

 

Did you check if they messed with the tuning/audio settings of the alpine amp,radio, or the cleansweep?

 

So he doesnt reply..........

 

well said, so much of the car audio industry is pure marketing BS...like the JL cleansweep.

to the OP, did you check the xovers settings ? I'm assuming the JL cleansweep has the xover settings for each speaker set (front, rear and sub). the cleansweep may have reset itself after the fuse blew. full on frequency range to all speakers will definitely make the sound horrible.

 

Pic of your car looksn great. Quick question...how did you attach a pic to a post in this forum?! I can't seem to figure out how. Thanks.
