Just do two obsidian 15s. 600Watts a piece and would do well on 1000Watts.

No turn

[what causes port noise?]

I did some measuring today and the port wall is 13.5" long and the opening at the back is 8.75"

Pro is thicker than regular damplifier. If your only doi.g the doors then 1 or 2 layers of damp should be ok

Im doin this from my phone so heres what I got

[what causes port noise?]

And I cant do a hairtrick.

[what causes port noise?]

Ok this is what I could get

[what causes port noise?]

Yes the piece behind the double is 12in. And I do have a 45 in the port corner

[what causes port noise?]

I used Torres to design the box and it told me physical port length 12in so thats how long the port wall is behind the double baffle. What I put in for port was 20in

[what causes port noise?]

No clipping dd1 tuned. Ive got 4 obsidian 15" dual 2s wired in series parallel at 1ohm on my rd 3250

[what causes port noise?]

The box I built is 49wide x 35tall x 23deep with a port thats 33.5tall x 6.5wide x 20deep it gives me 13.57cubes after displacement of subs and port. I didnt factor in the braces which are 33.5 x 1.25 and 20.75 x 1.25 round wood.

[what causes port noise?]

What exactly causes this? Im mainly asking because I think I have some in my new wall.

[Need opinions]

My 02 silverado has a stock 105a alt and im running 1 hc1400 and 2 hc2400 and not over heating it. Ive got all 1/0 wire and rd 3250 and no problems

[Need opinions]

[Atomic Quantum QT15D 15 Subwoofer info?]

They are great for sound quality. And that box you mentioned should work good mine is over 9 cubes and it seems too big

[Atomic Quantum QT15D 15 Subwoofer info?]

I cant say what they compare to, but you should be impressed with them. And if you ever decide to upgrade to something else I may be a potential buyer of the quantums. : )

[Second skin IS the best.]

Heres the roof. I didnt get pics of the doors.

[Atomic Quantum QT15D 15 Subwoofer info?]

Yes the d is for dual coils

[Second skin IS the best.]

I just recently installed ss on my front and rear doors of my silverado. I used one layer of damplifier on the doors and it helped ALOT. But today I had to have my headliner redone, so I figured id do the roof. I did 2 layers of damp pro on the roof. Before my roof sounded like tapping on a tin can, but now its like banging on an inch thick piece of wood. Everything sounds so much better. Thank you second skin for making great products!!!!

[WTB: 1200-2000W Mono amplifier]

I have an Atomic 1600.1. Rated at 1650 @ 1ohm. But im sure it does more.

[how do i do this?]

Mechman, singer, dc. Just to name a few.

[Time for another box!]

Thinking about just doing an spl build. What should I aim for?
