My 2000 maxima SE's bose sub had the common intermittent issue where it cut out randomly. I took out the relay and plugged the amp directly into subwoofer speaker. It worked fine for about a year with the pop sound whenever I turned the key to acc.
Recently it stopped working all together, I went to a scrap yard and got about 3 replacement subs and swapped them out only to find that the none will work.

Is there another fix for this issue that may have emerged in past threads? Maybe a fuse I could check? I hate driving with no bass in my music and I want to keep my sound system stock.

 

I had the same issue with the sub cutting out on my '03. The only real fix is to re-solder the points on the relay of the sub OR just replace the relay with an upgraded part.
It's tricky and requires a lot of patience, especially if you haven't soldered in a while. Some youtubers suggest using a piece of paper to apply pressure to the relay, but that's a bit mickey mouse.

Here's a explaining the process...
This is a very common issue for a lot of Nissan/Bose products

 

Thank for the input! I know it is something other than the sub since Ive tried 3 different ones. I have no relay at the moment I removed it a while back and the sub just stopped working a few days ago. I think the amp died so later today I'm going to the scrap yard to see if I can pull an amp and relay off another 00 max and plug in play. Will update after

 

Plugged in 2 different amps, 3 different subs. And different combos of each, still no bass. I have a 2000 which can bypass the relay but anyways do you know where to order a new relay?

 

search on here, there is a thread to fix bose sub issues and it has the part numbers in there, i did this properly with the new relay and soldered it and have no issues.

happy holidays, i found the thread for you. https://maxima.org/forums/5th-genera...-once-all.html

 

lesson here - do it right the first time.

 

Just an FYI: My Woofer's mini circuit board had optional soldering points so that an upgraded/larger relay could be soldered onto it.
Also, my main amp (next to woofer) needed new thermal paste near the base. The original pink stuff was not even making contact anymore. Takes just a few minutes to apply.

 

I've read most of those threads and I think I have a separate issue all together. The amp is not sending power to the sub, the sub is good the amp is good but they aren't communicating. I suspect a bad/loose wire. I'll update when I fix the issue
