my friend wants to know what will be the best option to go with he said he wants it to be loud and low i told him go sealed but i dont know what else to tell him we have the same car 89 caprice its down to three sealed or two ported 15's and i also know that a lot of people not a big fan of sealed boxes so can i have a options and opinions please
Being loud and low takes a lot of power and money. What I would recommend would be two fifteen inch subs in a ported enclosure that's tuned to 32hz but I would only go this route if I were running 1500 watts per sub.
