Im just thinking of a project in a few months and am hoping anyone could suggest a set up. Rite now i have 2 subwoofers Sundown 12" e-series in my 99 Ford Ranger.Im using 1200 watts for the pair. I'm thinking of getting a 15" SA-15 instead. Will i notice the difference. I wanna keep my setup up around 1000 watts. I don't really know how much the SA is better etc. Thanks for any info.
