Sealed up sides and carpeted the front. Blacked out the port and glassed areas. All bracing added and tightened except side to side. Rear wall ended up 3"thick. Foamed above between top and roof. Taped off pillar panels and added 2x4 pieces until only a small gap left then foamed in to seal the sides up. Once i trimmed the foam and pulled the.tape everything was flush for the carpet.

Yeah kinda...lol.
Still getting used to what plays best. Can get absolutely nasty on some frequencies! I think I may need to add a few more pieces to the top and bottom of the port to shrink some. Does fine 27 and up but I start to get a little unloading at 26 when I really get into it with the knob.

Both B2s mounted. Amps finally wired up and last pic is finished pic with subs mounted and port trimmed out. I'm pretty happy with how it all turned out. Alot of work for almost 2 months on it. Pretty much modeled it off of most other cpillar like Larry Gentry's build.

Review:
The ethos sound amazing so far. Highly impressed with them and how they are handling what I'm throwing at them. The m1s, what can i say....sweet like danish! Love the amp. Strong even on dropping voltages and haven't skipped a beat yet! Quentin and Jay both put out amazing products. Ive.been a.b2 convert for a while now and now DSS is coming strong with it's products.

No numbers yet, been breaking in and getting used to them some. Hope to have some as soon as this weekend. I have what I feel could be a.modest goal of 154 with this build. Anywhere close to that and I will feel it a success. I am a little battery limited right now and working on getting more 31's. Hopefully I can source a dual bracket somewhere eventually for a 2nd alt. Voltage does get to dropping after a couple hard minutes but I back off in the low 12's and charge back up pretty quick.
