I just bought 2 15" Power Acoustik Farenheit series subs and an 1800 watt amp. i know a lot of you don't like this brand, but i have heard power acoustik before and really liked it. but anyways, i don't know what kind of box would sound better... sealed or ported. i don't know if i will get 2 single enclosures (one on each side of the trunk) or one big box in the middle. i really don't want to take up all the space in the trunk. what do you think? i need answers fast because i plan on getting the box in the next 3-4 days. thanks for any help.
