im putting a sound system together to replace the stock one on my 04 ultra. i like my tunes LOUD...REAL LOUD. so far ive bought the j&m's front and rear and am looking to add a subwoofer for the nice punchy base. has anyone had any luck with a good product? if so, which one, where did you mount it, and what would you do diferent if you did it again?...thanks in advance.
