!!!BLINKY!!! Posted March 7, 2010 Report Posted March 7, 2010 Ok first off what im working with.. 1 DD9515 Hybrid. A Mmats M3000.05.. and got the Batt power to back it.. Ok now what i already have. A 4.3cuft box tuned to 38hz for daily use and doing a 141.0 @ 1 ohm clamped about 1200w and 145.5 @ .25 clamped about 2400w.. So im going to build a box for spl and i wanna know a good frequency to start at i was thinking about 50hz and go from there.. I have a second DD to use as well but i dont know if i have the room in my tracker, not a lot of room back there with batts and amp.. And the other think is how much will my score go up on an average? Thanks for the help guys... Quote HU...Pioneer 5900IB Wireing...Stinger Amps...(1) Modded Stetsom 2K6..

basshead4life Posted March 12, 2010 Report Posted March 12, 2010 use both subs at 0.5..... or 0.125 poof Quote Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol
!!!BLINKY!!! Posted March 19, 2010 Author Report Posted March 19, 2010 I did some testing yesterday and did a 148 at 40Hz under 2500w.. Im tuned way to low and my math on my box puts me at 47Hz but somehow im down at 40hz.. I wanna be up around 55Hz.. I should be up around a 150-151...
