Im trying to decide if I should do a 6 or an 8...
The box is 23x36x12 going in a 97 grand prix with only 1500 rms. Being as I don't know what frequency I like most since I have such a diverse taste in music, my plan is to build the biggest box I can and then experiment with different length aeros. I'll probably be making my own from pvc.Originally my plan was to make two 6" ports that adjust 2" (coupler), one 12-10 (32-34hz), and the other 8-6 (36-39hz).
The 6" gives me 6" per foot, will this be enough? 8 gives me 11.5"-12" per foot. Only issue with the 8" is it has to be twice the length and requires a 90 and a lot of volume and wouldn't be as easily adjustable. The 8" would have to be 28-23 (32-34hz) and 19-15 (36-39hz), in terms of adjustability that range won't be possible w/o making 3-4 ports. I realize I can just keep cutting it shorter, but Id like to be able to go back and forth to see the difference. The second concern is volume, the 6" nets me 4.5-4.7 (12"-6") but the 8 nets me 3.9-4.3.
My goal for this box is to increase my efficiency w/ added output. Currently running 3^3 @ 42hz w/ 11.5 per foot. Its way too boomy and horribly inefficient, I get some pretty bad voltage drop with my diehard platinum agm bat and 0awg and factory 105amp alt. I planed to upgrade to an ho alt, but Im hoping a new box will reach the mechanical limits b4 current limits.
How much difference will 1/2 cube and 6" of port area make? What's better for my intentions, big box small area or slightly smaller box with twice the area, and why?
Thanks
Sorry for such a long post btw....
