Kicker makes direct replacements for the 8" round shallow door subwoofers for Shelby Performance Parts. I installed them and they give much tighter base then the factory ones that boom. Typical 8" subwoofers will not fit in the shallow enclosures. Kicker Audio 8 Inch Woofers
Will these be a direct replacement for the stockers in a 13GT?
