is there a better sub then an Alpine SWR-1521D 15" Dual 2-ohm Voice Coil Component Subwoofer for the same price or cheaper? i want to get 4 of them should i get 15 inch or a different size
i powered 2 type r 1241d's and they kinda blew because they kept making a rattling noise after a week. I was powering them wih a RF 700x amp. I guess its to much power for them. but rf is awesome. i guess alpine subs have weak center cone rubber surrounding. Thats what i think made my subs rattle. But Rockford fosgate are # 1 in my list
