Want to see what box specs you guys have had good luck with for two 15" Digital Designs 9515 subs.

 

7 cubes @ 36hz

 

what vehicle ?

 

Its a cadillac escalade.

Also - which way would you recommend that I face the subs / port?

 

if you had 4 15s u could copy steve meades desgin he has all 4 facing up port back that seems to work well for him altho he uses 18s id recomend subs facing up tho

 

That is what I was thinking. (subs up / port facing to the back).

 

ya thats your best bet if u go to utube type in steve meads 30000watt tahoe its insane

 

is 4000 watts the right amount of power for the 9515? or will they run off 2000 watts. That way I could get four subs and keep my current amps (I am currently running four US Amps 2000x)

 

if you were running 2000 to each sub thats a good amount of power for each sub if you make the right enclosure thats gonna make up for the power anyways , so yes 1 amp per sub deffinitly is a good way of doing it if you went with 4 dd 15s facing up port back your gonna get the results you want i suggest running a few xs power d3100s tho and a 200 amp alt to keep the juices flowing

 

what does brad new mean?

I have had the two 9515 running in it but want more. I am either getting new subs or trying to rebuild my current enclosure as Father Yuli has recommended.
