OK i currently have a fosgate hx2 12'' sub, just for some bass for now.
Im looking to get a pure sq sub(s), i dont really know a size yet i just kno it i want it to be for sq. I was thinkin ether a focal 13'' 33a or a focal 16'' 40a.

If anyone has any seggestions or kno of any really good sq subs out there id really like to kno, cause im really just out to get the best possible sound i can get.
