^ haha

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.

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).

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!

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.

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

What do you do by the way?

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.
