Silverado budget build, options...

I have a nnbs crew cab with 4 sa8v2's under the rear seat forward facing. It's about 2.6 ft3 before displacements pretty much on the small side but freaking pounds just on 1200 watts(elemental designs nine.1). Your truck has more underseat space then mine does so I think you would have proper airspace for 2 10's ported. I would look into the fi ssd's they can work in an enclosure as small as .90ft3 and get very low and loud and actually have very nice sq.

Newer 06+ crew cabs are larger then 99-05 ext cab.

I thought the nnbs might have been a bit more tight but wasn't sure. IS it the bulk of the brackets or just tight floor to seat? Could you link me to the FI ssd's?

Also, where'd you mount the amp? I'm hesitant to put mine on the back wall for heat reasons. IT wouldn't be touching anything (esp. with the seat moved up) but I just don't see there being too much fresh air down there. I'd eat the entire under seat area with a box for 2 10's.

I LOVE a well built ported box though. Did a box for two of the DC level 5 15" in a buddy's truck, once the kinetics were healthy enough we blew the back window up. You could fit a child in the port lol.

this is the box I had built amp mounts under the box

Hey that's pretty cool! I never thought of extending the hump! Also, being forward facing and on the same side, I could just make the kid sit on the drivers side so the little muddy heels don't find their way into my drivers.

What truck did that go in, and is that a faux wood finish? Looks incredible if so...

Nice speaker, the options make it seem like it's a made-to-order sub. I bet their customer service is excellent if you roast a coil or something. I think it's a bit out of my price range for two at the moment.

I think I've zero'd in on the soundqubed hds310, two of them if I can manage. Reccomended minimum 1.25 cubes in a ported box, I can swing that, it will be a creative port that's for sure.

It says that it'd be a 44" sq port at 21" long. What's that 44" sq mean? Area of the port exit? I'd assume 4"x10" @ 21" length.

I owned a 00 gmc sierra.

Our floor is raised right below the bench seat and the seat bolts on each sode with two bolts each.

NNBS crew cabs have bucket seats that leave the entire floor panel flat allowing more space to be used.

Mounting a piece of wood to the back wall and mounting the amp should be fine.

The heatsink in most amps will help clear the heat.

Especially if you are going to be running anything lower then 2.5k watts.

They are built to order... Gotta be willing to wait for it lol... The hds10s should do you fine... Just know my box required me to lift seat 2" that's how I got it to 2 cu... You could easily go 3" seat lift and have plenty of air space

Look man. If you want something decent save your money.

I'm not sure I want the seat sticking up too far out the back window, there's only a couple of inches of leather before it looks bad through the window / obstructs the view out the back. 2.5" or so would put it right at the level of my toolbox viewing through the rear view... perfect for me. I think I will make it out of 2.5" square tubing.

Do you have the dimensions of yours or would you be willing to share? Anything you could give me would save me tons of time with the pencil!

 

[els1989]

You have to build your seat lift first... You can't really design a box until you can take exact measurements of what your going to be dealing with...

I've got a seat lift thread on here somewhere on how I did mine

I don't think I'm cheaping out, I'm just not going all out. This is twice the system compared to the last one I built for myself, and multitudes better than what's in there now. I'm a full time college student on a budget.

If there are better options at comparable prices I'd love to hear about them!

That's 2 cubes including port and speakers, correct?

Right on, thank you. I'm calculating 2.65 cu. ft.^3 including port, before speaker displacements if I raise the seat 2" and keep the trans hump like you did for amp clearance. Pretty spot on my friend!

 

[chubbza5]

Displacement is .33 cubes per sub, leaving me at 1.99 cu ft total box volume including port and speakers. Incredible how close they are!

 

[els1989]

Now you just gotta make sure they will mount without getting wedged

No way is the displacement that high bud
