^ haha :bowrofl: :icon30:

That bose amp looks to be smaller than a 2.5 hdd. I can't even believe they get off selling the Bose systems as an "upgrade". Yeah the base equipment sucks even more, but at least its easier and cheaper to swap out IMO.

Interesting "fix" though.

I am afraid to ask what the sub amp looks like.

I'm going to have to do this to my amp to. I'm having the same exact problem.

That is the subwoofer amplifier. The four-channel amp is a bit bigger so I opened it up to see what was inside and found that there were no power amplifier transistors only integrated circuits. And small ones at that. A big IC amp can put out 20-40 watts. These were tiny little ones and might be good for 4 to 10 watts (may be).

^ Thanks for the follow-up.

Where is the subwoofer amp located and how do you get to it?

I've been looking for a "how to" to do this, but I am having no luck searching for it. Can someone point me to it or explain how to do this? Thanks.

It's located next to the subwoofer on the transmission hump side. To get there you've got to do a bunch of work to strip off that whole plastic covering - basically start at the door sill covers and work backwards!

Damn, I thought that plastic cover was just a pop out... :icon27:

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.

Lol can you post those pics soon? I want to fix the relay lol =)

It's really not that hard. Once you get to the tiny amp and open it up, you'll see right away. It's enclosed in another plastic "box" that's gray, I believe. Just apply pressure on that and you're set.


Or, if you're gonna be a girl about it, I can always take mine apart and show it to you. :icon17:

Dude, you are a savior... you figured out what two different dealerships couldn't... you are the man! :thumbup:

What do you do by the way? :icon38:

marques1 07-16-2009 10:44 AM

your are the mother fing man it worked. Thanks so much!!

marques1 07-16-2009 11:38 AM

why is this not a sticky...this works for sure!!!

jubes 07-16-2009 12:23 PM

Yeah this should be a sticky...


anyone have a solution for the left front speaker dropping, possibly because of the speaker amp as well?

3hree5ive0ero 07-16-2009 03:53 PM

Stickied and first post edited. :)

marques1 07-16-2009 05:11 PM

Thanks for making it a sticky it deserves it. I've been without my sub for a couple of months now and this solved the problem. It only takes about 15 to 20 minutes to cure the problem.

3hree5ive0ero 07-19-2009 07:59 AM

^ I had to fix the spelling error while stickying it. :)

jubes 08-04-2009 05:55 AM
