If you put the new sub in where the Bose sub was like I did then there isn't any room to mount an amp under there anywhere. Even if there was there would be no easy way to access it without unbolting the console or cutting part of it open somewhere.

Na my subs will be going under the rear seat, but looks like my DD m2a would fit in the console fine where your new sub box is located. Just wasnt sure if there was a easy way to access it or not. Sounds like there isnt.

Nope. If you look at my first picture that is the console slid back at the bottom of the pic. That's what it looks like with the cup holder/storage are snapped off. There's a small hole there where the wiring comes through for the connectors but not enough for access to an amp.

If you rarely needed access it could work. It's pretty easy to slide the console back. Just pull the front storage area and outer side storage panels off, remove 6 bolts, unplug those connectors and slide it back.

Yea I was afraid of that. Ah well. I just dont like the idea of cutting out insulation to fit an amp. And my amp isnt exactly small lol

I'm still in the planning stage, still need to pull it all apart and run wires and build a custom box. So it will be a little while till I figure it all out.

Thanks alot!

Truthfully I dont need access to it very often, I use a nice remote bass knob so I really shouldn't need to get to it. But the factory radio also leaves alot to be desired when it comes to tuning...

Very true. I'm still working on trying to find the right balance. The bass control knob is a must have. Still need to figure out how I'm going to mount mine.

Anyone in here care to share how you have your LC2i set? I need to spend more time with it, but something just doesn't seem right with the balance on my setup so far. Hard to explain, but it just doesn't sound right.

I mounted my bass knob under the dash to the ac vent directly above the gas pedal. I have to lean forward to make adjustments while driving, but it's hidden and I didn't want to drill holes in my dash.

I was thinking about using some double sided tape to stick it to the side of my console high in the map pocket area. I have it coming out in that area now, but it's just draped into the console.

I have the Bose system without the console, meaning no sub.

Is the amp the same as the Bose trucks with the sub as without?

If so, anyone have the specs on the factory Bose amp, specially the sub output channel,

The Bose system minus the sub is around 200 watts. Not sure what the sub amp is it’s def not powerful most likely to not rattle the center console. I added a second sub from kicker and left the Bose sub hooked up.

No experience with that, but I'd guess it will work fine. Quite a bit more expensive than an LC2i or even an LC7i though.

Yes mine does, all of it. The center console is ON the box snug, If I can I'm going to make it have a few mm between the console and the box. I don't like that it's that snug.

If there is that much interested here is what I'll do.

I'll use the extra material I have to refine my fitment make sure it's reasonable, and post new pics. Basically I want the center console to fit perfectly for you, I had to work at it to get everything back together just right. Then I'll put a few out and see what everyone thinks. If there is more interest I can take more orders.

Just to be upfront with everyone I'm traveling for work on Sunday and will be gone a week, so the earliest I'll be able to get started building these would be 3/10. Maybe sooner but realistically it would be that weekend. I'll get the second version made this week if there is interested which it seems like there is.

Once I've refined the design I'd sell them for $200, seems to be the going rate for an empty custom stealth box these days. I have no idea what shipping would be because I haven't weighed the box yet and I'd need your ZIP to calculate it.

If you are interested in me building you one of these send me a PM with your ZIP.

I'll need 5 people to be serious about it though, which it seems like there is already so just PM me and we'll work the deals. We can do Square Cash, Venmo, or PayPal. 50% down to cover materials and the balance before shipping. I prefer square cash but if you're more comfortable with Paypal that's fine.

The only other stipulations would be speaker type and that I can only guarantee it to fit the 2014 Sierra 1500 Crew Cab with bucket seats and the Bose subwoofer. If you don't have that truck buy at your own risk. I imagine any 2014-2017 with bucket seats and the center console will have the space but I can't make any guarantees around that.

One additional note is that I did have to trim the bottom part of the dash, it looks like there were mounting points for plastic panels in the trucks that didn't have the center console. I couldn't tell from andreej's pictures but it looked like he did the same thing. If you look at my pics you can see the part that I trimmed just above the box. It serves no function in my truck and won't affect the structural integrity of the truck, or your ability to revert to the stock sub.

Only fits:

2014 Sierra 1500 Crew Cab with bucket seats and the Bose subwoofer

JL Audio 8W3v3-4 8" Subwoofer

Includes

Custom Box, glued and screwed.

Gold plated speaker terminal

Black Rubberized coating. (carpet won't fit)

I may update the design with brackets if the fitment requires it after I rebuild it.

P.S.

andreej, if you want first dibs on the sales, just say so, I don't want to step on your toes since you did this first. I just used your idea and guessed at the measurements. I don't know how to mention users without quoting so hopefully you see this.

I'll make a separate post with the people who have asked so far because I think there were already five. First come first serve an all.

Would you still be interested in making one of these boxes and shipping it to Alabama?

I also installed the 8" L7 custom box from Rodney's boxes. It is a step up from the Bose but not going to rock your windows. I had originally had the LC2i wired taped from the factory sub output but wasn't very happy with the factory bass roll-off and DSP mutilation so I swapped out the LC2i for a Nav TV M650-GM canbus converter. It is much more expensive but the sound is way better with a distortion free RCA preamp signal.

Or you could do what I did - Sub floor mounted 2.5 cu ft subwoofer box, Alpine Type-R 15", uses a minimum of under seat storage area.

The box fit right in front of the fuel tank and after covering it with fiberglass and undercoating it looks almost OEM (and you only see it if you crawl under the truck).

Obviously a major fab job including cutting a 12" square hole in the floor but I thought someone might find it interesting.

(hole was framed with 1/4" steel and is much stiffer even with no box mounting than the original 20awg flat steel in this area. Upper and lower box sandwich the frame and clamped with 12 bolts).

Sounds awesome and will massage your brain out if you put on rap music. Funny thing is I'm all about hi fidelity and usually listen to light jazz, but I tend to get carried away with things.
