[fusionprelude]

i have a kicker amp and a fusion powerplant sub amp puts out 404rms into 900 watt sub wot db should this give me???

[integraz]

too many variables..

but i think mayb 130db?

how big is box?
ported? if so tuned port to...hz?

[fusionprelude]

i custom done the box but its too small i think.its more of a shallow mount box. its ported now but i just slaped it in i havent tuned it just yet. i made it to 10" specs of the fusion powerplant one

[Slow96GSR]

130-140ish is my guess!

[GRU53M]

120-128 tops

yeah i say around 130-5db, but why can't u just put it on the termlab and see how its goes?

i custom done the box but its too small

if its too small, make a bigger (more optimal) box.

heres a quick sub+bigger box VS small box comparison (strictly talking about loudness/db).
smaller: sub needs MORE amp power to b as 'loud' compared to a 'optimal box'
bigger: doesnt need AS MUCH amp power compared to a smaller box to go loudly, but too big a box may make ur subbass 'sloppy'

got specs of ur sub & box??

looks like ur keen on gettin the most db out of ur system, so ur planning on entering SPL comps??

box size is all about compromises..
