Jonathan91v8 Posted August 2, 2020 Author Report Posted August 2, 2020 I have a blow through on my truck. They will be wired at .66. i have two yellow top optimas with a 220 alt with all 1/0 wire. As for the box itll be 3 cuft sealed and 7.5 after displacement tuned to 45hz. I have sound deadening here and there.
1point21gigawatts Posted August 3, 2020 Report Posted August 3, 2020 If you want good numbers you are gonna have to take off that port and cut a bigger one with about 120-150 square inches of port area per cubic foot. A 4th order enclosure that doesn’t have enough port area doesn’t get loud and a regular pre fab ported enclosure would get louder. I know this for a fact. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.”
Jonathan91v8 Posted August 6, 2020 Author Report Posted August 6, 2020 Ok cool. I've got my other sa12 yesterday so i'll be making the box this weekend. So for a recap, i can make the box to be 8.5cuft ported side and around 3cuft sealed after displacement and make the port 8x21 to have 168 of port area and 10.5 deep to be tuned to 50hz. Would that work?
