I am about to set up an audio system in my 99 GT and was wondering which sub to go with. I am set on the Polk Audio SR line, but am torn between the 10" and 12". I listen to hard rock/metal (Disturbed, Metallica, etc.). I know 10s are usually recommended for this style of music for the quick drum kicks, but I see that the SR line is really set up for SQ. I am just worried that the SR10 will not put out enough volume. Would the 12" be able to keep up?
