Smile double the power .5 ohm

Went to a competition today in Escondido qualified in at 144 with my 4 flxx 15s tuned to 35 hz in a 13cubic foot box @2 ohms on crescendo bc 5500 with peak freq of 50 at first then i decided to just drop it down to half ohm 4 d4 subs...

so at first they were seeing around rms counting on crescendos rating of 2800 @ 13.8 @ 2 ohms (flxx 600 rms) haven't clamped but wasn't getting much voltage drop lowest 13.9 anyway

took out the subs started to re wire them to a .5 load turns out my turn comes around too compete in bass race(subs still out of box) got dqed they gave me a chance an skipped me but i still wasn't ready

well anyway dropped down to half got it metered & hit 148 with gain set according to sound no dm1 available they got kinda stinky lol but hey what do i expect for more then double the rms (600) not sure exactly what each are seeing after drop but i know its atleast double, i did see more drop in voltage though i need to upgrade to a better alt i have a shop built one right now & 4 cnd 400

my bad about long ass story just bored.

& title just meant i added 4 db with double power lol
(still lower then expected though) gotta do some work

Try shrinking it. Dont go under 11 cubes though. They dont like it. And like 13-14 sq inches of port per cube.

What metering style.

to be totally honest i had someone build it i didnt know the cube of the box until some of the buddy's helped me take um out an rewire them then they wanted to know so measured it it was 12.97
i dont know the process of shrinking it either

4db is a HUGE gain. I doubled my power and only saw 2.5-3ish. I would be happy as hell with that

Lol. So hard to read, but interesting points.

My guess as to why he saw more than double the power is that he also cut his rise in half or more (theoretically) since he went from 2 ohm to 1 ohm and then 0.5 ohm. I did this with my 1000.1 from 2 to 0.5, went from 150.4 door open to 157.4, lmao. That also might be the subs breaking in, lol. But on my AMD-1 I went from 5400W max to 10400W clamping. Box rise went from 2 rising to 4.4 to 0.5 rising to 1.6/1.7.

Get some better subs that can take the power and run that daily. Any idea on your box rise?
