Used to be big into car audio a decade ago, since then new companies have popped up and I'm totally lost again. In an effort to keep this short, got a 2014 mazda 6, don't want to upgrade the alternator(110A?), but big 3 and battery are on the to-do list, so my guess is 12-1500w max for a single ported 12" for daily use without having power issues. Looking for a recommendation for what you think the best SQL sub is in my situation if money weren't an issue. Years ago I would've just gotten an Adire Brahma and called it a day (or a RE XXX, which is still on my possible list), but there's Digital Designs, Ascendant Audio, Incriminator Audio, SSA, Sundown Audio, Treo, RE Audio, etc etc etc holy hell too many to choose from! Just want amazing but loud bass for daily use in the 12-1500w ballpark. GO!
