Replacing stock subwoofer.......

[David Paul]

in another thread, the question was asked if just replacing the door speakers was worth while. The consensus was that it is. I did it and was happy with the results. I have upgraded the HU to an Alpine unit and would like to replace the stock subwoofer. Has anyone done this? If so what speaker did you use? I have an 04 Tahoe with Bose so the subwoofer is in the center console. Thanks for your thoughts...

I've got an 04 too, I've been thinking about it as well.
I was curious if something like this Kicker might fit, but I don't know what kind of room we're working with.
Judging by the top-mount depth alone, this could fit in our doors if you so wanted

I found out that there is a top Mount depth of 3.75", but what I don't know is how the bose speakers are wired, if they are svc 2ohm or a form of dvc (doubtful). If you end up finding out any more information or decide to guinea pig it, let me know the set up you go with.

Thanks John. I'll probably get into it next week. I'm kind of surprised no one has chimed in that has done this already. I'm not looking to blow out the windows but if I get as much of an improvement as I did with replacing the other speakers I'd be happy. Then I'd have enough $$ left over to get a BB tune......

No problem man. Usually takes a few days to get the answers you're looking for, I replaced all my doors, and I have a 10" sub in a Q-Logic Factory fit box under my 2nd row, I just figured by the condition of my other speakers considering they are 12yrs old, I'd want to replace the sub too. I just want to be able to squeeze a bit more upfront low end outta the console, even if it's not much, it would be a cleaner and/or crisper bass tone

The subs are 2 ohm DVC units if i recall correctly. There's a few decent AM options out there that will fit the height space although i don't know about circumference as I've yet to dig into my console. I would think any mods under the console won't matter anyway. I'm thinking though that unless your existing sub is DOA though, I'd just as soon leave it in for some (very) mid lows and instead add an actual box in the back or under a seat with a separate amp. You'll have better sound and better overall control of it. Not to mention that smile you had after the speaker swap... From what I've noticed with mine is that the quality may be OK but I have to push the limits of the remainder of the speakers to almost distortion just to get enough audible bass signal to the sub to be worthy anyway.

Hum, from what you guys have said, it sounds a little more involved then I thought. Ohms I understand, but what is this svc v. dvc comparison?
Update: I looked it up like I should have before posting the question and found the answer. Single v dual voice cones. That I understand as well as the wiring options......

If it works why not add a sub to the rear factory spot the 00-02 used? Can get MTX thunderstorms or a junk yard box out of a wrecked 2000-02

 

[David Paul]

MTX = $$$$. If I could find a box from a 00-02 I would try that, but some reviews aren't so good on that mod.

 

[treehan77]

MTX is $ true. The 00-02 mod would surely allow for a better/bigger sub than the console. And you'd have two then assuming you're factory is working

Wish I had an extra grand. If buy mtx and jl audio boxes

So I changed my mind after reading all the comments and suggestions. Since a had replaced the HU with an Alpine unit that had line outputs, I went with a Alpine compact powered sub. Installed under the rear seat. Kept the working stock sub. All in for $310, and about 10 hours work. Taking my time, I need to remove the rear seats to modify the bracket so the sub fit where I wanted it and custom made mounting brackets. Front seat lossened to run line cable away from power wire. All in all I could not be happier. Fills in the sound I was looking for, didn't take up cargo room, and not too much $$$ for what I got.

seems to fit very nicely

Only issue I have with it, is the seats done 60 side of the 60/40 seats dont fold down more than about halfway. Not a big deal for me, I don't haul stuff too often that requires me to do that.
