[QUOTE="mecaspl151, post: 6080532, member: 609492"] 18's im getting 1 more 3250.1 as soon as steve call's me next week i hope and im running the 1 i have at .5ohms now and tuned to 32hz and my tires flex as much as my windshild lol but i wonted to know about the tuning it to 36hz by cutting my port down for a comp sunday but im going to have to make my port 14" deep aposed to 21.5 and i dont wont port noise or hurt anything by doing it her are the specs on the amp but @ 0.8ohms and i running mine at .5 so i dont know The RD series amplifiers deliver a ton of power with a low distortion rate. We used the best parts we could find to give you a top quality amplifier that anyone would be proud to show off. With their clean looks and sleek finish, they’ll look good in any install. So whether it’s an elegant sound quality setup or a high powered SPL vehicle, the RD series amplifiers have you covered.
