D-train-13k Posted September 23, 2011 Report Share Posted September 23, 2011 Hey Notoriousj76, before we go any farther, are you sure your enclosure is 15 cubes ??? ...even after sub and port displacement ? This is REALLY huge, for an enclosure, "other than" a walled vehicle. So I guess you have this in a large SUV or a van ? ~~~~~~~~ Anyway, I typically decide on what subs, and how many, "then" build the box to optimum specs for those subs. But if you really do have 15 cubes (net) to play with, yes, actually it probably would work well for four 15"s. You'd still need to model them, to figure out your exact porting. But probably doable. Peace, Fish Ok thanks. Before I had this setup I had an orion hcca 15 in 8 ft3 total. Sounded almost as good but I traded it for these subs, and they are only single coils. I got lied too and didn't notice how "not loud" they were untill later when I put a multimeter on them and got no reading out of the other coil's terminal on each. If I put 4 15's in there do you think it would be sutible? Or should I just build another box and up my wattage? I'm trying to save money and be as loud as possible. Also, I prefer low tuning. 33 hz probly on my next enclosure. OP says it was in a 91 astro van. but yeah i would design up a box and post it on here so you can have some of the more experienced guys help you.

Notoriousj76 Posted September 24, 2011 Author Report Share Posted September 24, 2011 So my options (without building another box) are get 2 more 15's . or swap mine for some 18's that love lots of volume? Either way I'm running only one sae1200 once it gets repaired. Not a lotta power for something so large but I like to go balls deep when I can and I could with my box, although it backfired lol.
