Bass Drop Out
I have a 03 with the Bose system. Recently bass began to drop out randomly. It comes and goes. Do any of you folks know if it’s the amp or HU?

I have the same problem, and i had an aftermarket head unit with the bose amp and speakers...anyway i went to an audio store and they said 95% sure its the amp because when the base came in it sounded good...they said they can fix the amp though GL

There was a TSB and I had mine checked within months of buying the car. It was a latter model that did not fall under it.
I am a newb at car audio but if the AMP is the problem than how can replacing the HU fix it?
Thanks for all your help.

Now my left speaker is low and pretty much obsolete when on, as well as my sub, while I'm bumping there is slight "popping" at certain peaks...
So I'm guessing it's either connection problems or the amp... I have an 03 touring and the problem is only occuring now which is pretty good in my opinion, but I think I might do an aftermarket amp that matches or is higher than the OEM specs of the stock amp. And atleast when they are installing the amp they will be checking connections, so it's like a two birds-one stone scenario.
Has anyone tried this solution? Does anyone know the factory specs on the OEM amp?

Okay after reading 9 freaking pages of "bose amp sub" searching... ultimately it comes down to the speaker amp and the sub amp being sub-par.
Some people have suggested of replacing it with another set of bose speaker and sub amps, possibly used ones from members on the forum.
No one has really answered the question if the OEM speakers and OEM sub could be used with aftermarket amps especially the question of if the wiring of the OEM components is even adaptable to aftermarket amps because of Bose's awkward sub-par design of the speakers and sub.
I personally think for common use/DD use it's a decent set, obviously I wouldn't do a sound competition with them, but for DD use, I would really like to keep them myself.
Hopefully someone could answer the question of aftermarket amps being used on OEM speakers and subs, and what specifications are necessary to make the aftermarket work with the OEM.

If you are experiencing a problem with the junk OEM stuff, but are not willing to do a complete replacement ($$ is certainly an obstacle), just find OEM junk to replace the stuff that isn’t working.
It’s foolish to attempt blending good components with OEM junk. Don’t do that.

OEM amp problem found (at least in mine)
After listening(I make my living with my ears) the intermittent pop and subsequent dropping in my amp is because of the relay in side of the amp.If you open the amp you'll see a little white box. It is the relay. I applied a little pressure to the top and the amp started working. This was done after checking every connection in the amp. I released the pressure and the sub quit working again.Not wanting to track down a replacement relay I simply cut a piece of solid plastic the diameter of an pencil and positioned it on the lid of the amp to keep pressure on the relay. This by no means is the best way to deal with what is clearly a bad design on Nissans part but it has worked for me for over a year with no dropping out.If I ever have to open it up again I'll post pics. Pretty easy fix.

If you open up the amp itself, which is enclosed in a metal enclosure, you'll see this gray box on the circuit board. I made my sub go out first on purpose (by increasing bass) and then applied pressure to see if that indeed would correct the problem (while the amp was taken apart but still connected). Lo and behold, it actually solved the issue and I blasted everything to purposely make the sub go out again with pressure applied, but it held up fine. BTW, I have an aftermarket headunit with its own amp, which also allows me to crank up the "bass" more than the stock headunit.
I just folded up some printer paper and taped it down to the gray box, then closed the enclosure back up. One corner of the enclosure was lifted up maybe a little under 2mm, which I felt was enough, when the enclosure was put back together. Then when you put the screw back it, it will hold the pressure onto that gray box.
Anyway, you probably can't imagine this in your head, but once you start taking things apart and see the actual pieces, it will make sense.
Thanks again for posting this little trick.

This problem has been coming up for years and years. In the past I've sent people to check for loose connections in the back on the amplifier and the speaker ... and they stopped complaining. I'm assuming they're finding the problem. The stuck relay might be the problem. I'll keep that in my bag of tricks.
