Wassup guys I'm doing a port swap in the next few days and trying to get opinions/suggestions. I have a box 39.5h x 41.5w x 13.5" d (outer dimensions) with a port 12h x 10w x 40" l which gives me 6.8 cubes tuned at 31hz with 17.75 port per cube. It's just not giving me as much pressure I want on lows. The new port is 12" o.d. Pvc (11.5" I.d.) x 36" l with 2-4" external. This will give me about 8 cubes tuned at 29 with 14.25 p.p.c. I don't have anything to lose, and I'm not building a new box until I design a 6th. So what are your thoughts on what I have now?
I have for sale two crescendo bc 2000 for sale both are about 1 1/2 years old good deal power by two g31 batt juciebox, and crescendo logic...pushing 2 18" ethos strapped at 2ohm never seen below 12volt...I had to push them....got warm in this hot Kansas City weather...both will come with bass noobs and one with owners books the other might be lost during a move with both boxes from crescendo...I love these things they both went to db-r for repair but nothing major I had a bad ground and thought I blew them both

I'm upgrading to a bigger amp dd-m4a
So I'm been on the web looking at different types of 5k amps that are linkable amps, so I can upgrade my current amp set up...I'm looking for a amp out of these new or used- dd m4a, sundown audio 4500, crescendo bc5500, dc audio 5k, ampere audio 5000.1. It has to be able to do around 3800-4000 wire down to 1.3ohms.
Running 3-18s DSS ethos box is in the works....
Electrical is dual alts stock will run the truck, mid, and highs the singer 270amp will run only for the battery bank. 4 juice box blackcherry battery back, two runs of 1/0 wielding wire.
( would like more batts if space would allow)
( playing music daily and burbs on comps)
I'm not looking for a father and son conversation here just wanting to know which amp would be better suited for my set up that's all thanks for reading.
My current setup consists of:
-Advance auto parts group 34/78 up front
-stinger spp1500d in the back
-mechman 270a alt
-Knu konceptz 1/0 all around including big 3
I was wanting to upgrade to something bigger (maybe a dc level 6 18). I am tore between 2 options...(both options will have c1100.4 and same batteries plus some later down the line)
-2 positive runs of sky high 2/0 from front to back
-3 positive runs to the amp
-Big 3 in sky high 2/0
-Another bc2k strapped to the other one
-1 run of sky high 2/0 from front to back
-2 runs of knu 1/0 or 1 run of sky high 2/0 to each bc
-big 3 in sky high 2/0
I can save money going with another bc, but would the more efficient taramps be a better option? Im just curious of yalls thoughts on the taramps.
