At a recent Car Audio show ...I ran my Saleen with a single DD 9510 in the trunk on 1500 watts...I went against a small suv running a JLW6 13 in a portedbox on 1800 watts...my trunk car hit nearly 4 dbs louder...my DD played lower...my DD sounded better...The guys Jaws dropped after sitting in my Saleen and hearing a single 10 PWN his JL almighty...lol
