[QUOTE="blazian87, post: 8249075, member: 574798"] I have a 12" Fi Q in a ported enclosure with 2 12" passive radiators. It's about 2.5 cu ft net volume tuned to around 30 hz for SQL purpose. I'm very pleased with how it sounds right now but want to go louder. I'm currently running the AQ2200 amp at 1 ohms to get full potential. Most of the time I have my gains pretty low and it's quite loud already. I think it sounds just fine with about 1500W without distorting. I have 2 extra Fi Q's laying around and I can't make up my mind. Everyone keeps saying 1 ported will be louder or that 2 12's will be about similar output. There's many variables to this because if I go with 2 sealed, then I will be running it at .5 ohms. I will be putting them in around 1.6 cu ft each, which is on the bigger side already. It's the most I can fit in my trunk. I have a singer h/o alternator installed already and XS 5100R battery under the hood. If I decide on the 2 12's at .5 ohms, I will add a XS D2400 battery that I have laying around to my trunk. The whole reason I'm doing this is to maximize my power and space that I have. I cannot fit a 15" in my trunk so it's either stay 1 12" ported or go 2 12's sealed. Ultimately, it has to sound good or else getting louder doesn't mean anything to me. What changes do you think I'll be hearing switching to this setup? Will I lose those deep lows but gain more up top? Will I be louder overall?? Will I have better SQ? Any input is appreciated..
