Actually to make it loud what u need a powerfull amp and some eq setup for that purpose.

you dont need to be powerful to be loud. you want loud with lower power rating, change your box to a ported tuned low around 30hz. go for the biggest box your boot can afford.

why not consider 2 subs than 1? 2 subs is better than 1.

yes i am using 2 CVR ported in a box tuned 33hz at 4.5 cu. ft.

I've a boot constraint which allows me to use only 1.05 cu. ft sealed enclosure. Since I've space constraint, to make it loud I've to rely on the power of the amplifier. But if space is not a constraint, then big box is recomended. So far I feed my sub with 380 watts RMS at 4 ohm (some people said that this amp is overated) and still manage to get 135.9dB for my IASCA JB Heat w/out full blast (as requirement only 135dB for full points).

appleyard,

wow.. you got a really big boot with space to spare.. must be driving a 4x4 eh? I wont mind doing that if I have a dedicated show car whereby bootspace is nto so important.

yong,

to tune the box, you will need to get the Thiele-Small (TS) specs of ur sub. plonk it into WinISD and then use it to calculate the size and port length for ou.
