Well I'm never really active here any more buy I need some ones help with 4th orders. Now this setup will be super daily I am not in search of numbers at allllll. Right now I just received one sa 12 and I am trying to sell because I think two sa 10s would be best, how ever I'm wondering if I could just grab another sa 12 make it easier on me not having to make a sale and ship a woofer out. So my question is would 2 sa 12s perform well in a smaller sized 4th order? Or should I really just do sa 10s and maximize the potential of the 10s? We don't have a ton of room to work with and honestly I would like to only take up half the trunk .
